Best AI Cricket Apps (2026): Scoring, Bowling Speed or Bat Sensors

Search for an AI cricket app and much of what comes back is not a training tool at all. Prediction apps, fantasy team pickers and cricket games all use “AI” in their names, and directories list them next to coaching apps. We leave betting, fantasy and prediction apps out of this guide entirely, along with games. What is left still covers three different jobs, and the store pages rarely make the difference clear.

One kind of app scores your match ball by ball and puts AI on top of the scorecard: highlights and insights. A second kind watches video from a phone on a tripod and measures each delivery: speed, where it pitched, the line, and sometimes the batter’s shot. A third kind is a sensor you stick on your bat, with an app that reads your swing. Each needs different kit, charges in a different way and sends your video, or your child’s, to different places. This guide compares six AI apps across those jobs, plus two non-AI tools as benchmarks, for club and school cricketers, coaches and parents in India, the UK, Australia and anywhere else the game is played.

How we reviewed these. We have not used these tools ourselves. Every price, rating, date and feature below comes from the app’s US or India App Store listing, its Google Play listing in India, or the vendor’s own website, pricing page, FAQ or privacy policy, read on 8 November 2026, and each source is linked. US App Store prices are in US dollars. India App Store prices are rupees, as the store showed them in India; we do not convert them, and they may differ where you live. Speed and accuracy figures are the vendors’ own.

Three jobs called “AI cricket app”

Work out which job you want done before you compare prices. It decides what you need to buy, where the phone goes and what you get back.

AI on top of a scoring app: CricHeroes

A scorer taps every ball into the app during the match, and the app builds the scorecard, the wagon wheel and the player stats. The AI part comes after: automatic highlight clips, and analysis of a player’s form across the matches that were scored. Nothing here watches technique. The data is only as good as the scoring, and the highlights depend on someone streaming or filming the game.

Camera analysis of each delivery: Fulltrack AI, Ludimos, Matcha, Clean Bowled

You put a phone on a tripod behind the stumps or at the side of the net and bowl or bat as normal. The app finds each delivery, cuts it into a short clip and estimates what happened: release speed, where the ball pitched, its line, and with some apps swing, spin or the batter’s shot. This is what many net bowlers mean by an AI cricket app, because it answers the question every bowler asks: how fast was that? The camera position matters a great deal, and every vendor here tells you exactly where to put it.

A sensor on the bat: str8bat

A small sensor clips onto the top of the handle and talks to your phone over Bluetooth. It measures the bat, not the ball: bat speed, the angle of the backlift, impact and timing, with a 3D replay of the swing. The AI part is the coaching layer that turns those numbers into tips. You need to buy the hardware, and the app may need a subscription on top.

AI cricket apps compared

Read on 8 November 2026. Ratings are rounded to one decimal, with the number of ratings in brackets. Play figures are from the India storefront. Look at those counts before trusting a star rating. CricHeroes has hundreds of thousands of ratings, Fulltrack has thousands on Android, and the rest have a few hundred at most. Three of the six had no App Store ratings or a single one, so a five-star score from one person tells you very little.

How we chose and ordered these

Every app in the numbered list had to describe AI analysis of cricket in its own words, have an update in the last 12 months, and publish a privacy policy or privacy statement we could open, because these apps handle video of children. We ordered them by job: the scoring app first, then the three camera apps that measure batting and bowling, then the speed-only app, then the bat sensor. The order is not a score. Two tools that make no AI claim sit in their own section near the end as benchmarks, and apps we left out are listed with the reason.

The six AI apps

1. CricHeroes: free scoring with AI highlights and PRO insights

CricHeroes, from CricHeroes Pvt Ltd in India, is a scoring app first. Its App Store listing says you can score ball by ball and get an international-grade scorecard “completely FREE”, with charts such as the wagon wheel, Manhattan and worm, live streaming from a phone or broadcast software, and free tournament pages. The AI claims are two. The listing says you “Get automatic AI-generated highlights of your matches after every game.” It also says “Use CricInsights to analyse performances, track your form, understand your strengths, and improve your game.” The vendor’s own figures are “40M+ users, 10M+ matches scored”.

CricInsights is the paid part. The CricHeroes PRO page lists batting and bowling insights, a head-to-head “face off” against another player, team and tournament insights, and insights before, during and after a match. It does not describe these as AI, and it does not show prices in the page text.

What you pay. Scoring and tournaments are free. On the US App Store the purchases are Pro Yearly at $24.99, Pro Monthly at $9.99, Pro Quarterly also at $9.99, Pro (90 Days) at $1.99, Pro (One Year) at $12.49 and Pro Infinity at $69.99, plus a Player Highlight at $3.00 and live stream passes from $2.49. On the India App Store, prices are in rupees: Pro Yearly ₹399, Pro (90 Days) and Pro Quarterly ₹199 each, a 1 Year Offer at ₹200, Player Highlight ₹29 and Match Highlight ₹49. The India store also lists Pro Monthly at ₹999, more than the yearly price. With several plans of similar names at different prices, check exactly which one the app offers you, and whether it renews, before you tap buy.

Data and age. The privacy policy says “Users must be 18 or older. If under 18, usage must be supervised by a guardian.” The App Store page rates the app 13+. That matters because many players scored on CricHeroes are juniors, and their names and stats appear on shared scorecards and on city, state and national leaderboards. The policy names Google Analytics, Firebase, Twilio and AWS among its tools, says cookies help “Deliver relevant advertising”, says it does “not sell personal data”, and shares limited information with cricket associations, tournament organisers and the ICC. The policy says it uses YouTube APIs for live streaming. The App Store label lists usage data as used to track you across other companies’ apps and websites.

The iPhone app had 4.6 from 728 US ratings and 4.7 from 29,549 India ratings, updated on 6 November 2026. The Android app had 4.8 from 382,262 ratings and 10M+ installs in India.

Choose it if your club or school wants free scoring and a season of stats, with highlights as a bonus. Skip it if you want feedback on technique, which a scorecard cannot give you.

2. Fulltrack AI: ball tracking and DRS from one phone

Fulltrack AI, from Maiden AI Inc, puts a phone on a tripod and tracks every ball. Its App Store listing says it uses “machine learning and artificial intelligence technology to analyze your cricket performance”, with 3D ball trajectory, pitch maps and ball-by-ball video, and that recorded video and data “is then stored in the cloud”. The website lists auto-clipped videos, speed, swing, spin, DRS and pitch maps, and auto batting highlights sorted by line and length. Its pricing page says “Ball tracking costs $100k+. We’re different.”

The setup is strict. The FAQ asks for 6 stumps, 3 at each end, and a tripod ideally at 1.3 metres, placed about 4 metres behind the non-striker stumps. When the data looks wrong, the FAQ’s first answer is that “Inaccurate data is often due to setup issues”, and it lists a taller tripod, the wrong distance and a bowler blocking the camera in the follow-through. It needs an internet connection to process, though you can film offline and sync later.

What you pay. There is a free tier, and the website’s prices load by script, so we read the plans from the US App Store instead. It lists Individual at $19.99, $71.99 and $119.99, Individual + Monthly at $50.00, Individual + Yearly at $300.00, Coach+ at $149.00 and Coach at $479.99. The store does not show the billing period for every plain “Individual” item, so check the period in the app. The India App Store lists the same plans in rupees, from ₹999 for an Individual plan up to ₹29,999 for Coach. The pricing page says schools and premier clubs need a Coach Plus licence and professional teams an Enterprise licence. Real-time DRS is sold only to ground owners, leagues and organisers, with “a minimum 50 game commitment and per match pricing”.

Two limits to read first. On the free and Individual tiers you “may only film 1 distinct batter and bowler”, and the FAQ warns that an account may be restricted if you film more. And any paid licence is “linked to a single device”, with a move to a new device allowed once in 14 days. A coach filming a whole squad on one personal plan is outside the terms.

Data and age. The privacy policy was last updated on 12 May 2023 and says the app “is not intended for children under 13 years of age”. It lists video and audio, contacts and location among the data it may collect. The FAQ says Coach+ and Enterprise data is never used for marketing, and that subscribers can hide sessions from the Global Feed. Ask Fulltrack whether free sessions appear in that feed before a junior films there.

Fulltrack quotes two user numbers: “Join 2 million+ cricketers” on the pricing page, and “200,000 others” in the FAQ. The iPhone app had 4.3 from 40 US ratings and 4.4 from 186 India ratings, updated on 29 October 2026. The Android app had 3.7 from 6,223 ratings and 1M+ installs in India.

Choose it if you want ball tracking with DRS and can set up stumps and a tripod properly. Skip it if you want to film several players on one cheap plan, or the player is under 13.

3. Ludimos: AI clipping, skills and a free tier of 300 clips

Ludimos, from Ludimos BV in the Netherlands, aims at both players and clubs. Its App Store listing says “AI Action Clipping turns 60 minutes of match or net footage into 5 minutes of pure action”, with automatic batting, bowling and biomechanics analysis. The homepage says the phone goes at the side of the net and that Ludimos “measures every ball to the centimetre”, a vendor claim with no method published. It also offers Skills modelled on famous deliveries, where you must land six balls in a target zone to pass, and leaderboards with friends. Version 6.0, released on 6 November 2026, lets up to three extra phones join a session by QR code to film more angles.

What you pay. The homepage lists prices in US dollars, with rupee pricing through Razorpay. Free gives 300 local clips with no cloud sync. Core is $4.99 a month for 500 clips kept 90 days, Plus $7.99 for 1,500 clips kept 180 days, Pro $11.99 for 3,000 clips kept 365 days, and Max $20 a month with unlimited clips and AI analytics. On the other tiers, AI analysis comes from credit packs: 30 for $4.99, 60 for $8.99 or 120 for $17.99. Club packages run from Starter at $149 a year for 15 members to Elite at $749 a year, with AI batting or bowling analytics as $49 add-ons per period, and a 14-day money-back guarantee. The US App Store lists Core at $4.99, Plus $7.99, Pro $11.99 and Max $19.99.

Rough edges. On 8 November the homepage still carried unfinished copy. Its testimonials were followed by a line calling them placeholder quotes to be swapped for real player testimonials before launch, and a second pricing block showed Pro at “£X / month CONFIRM PRICE”. Treat the player quotes on that page as samples, not reviews.

Data and age. The privacy link in the App Store listing went to a “Page Not Found” error. The privacy policy linked from Ludimos’ own site says children under 16 cannot register “without parental consent”, which it says it will verify, that it processes data in the European Union, and that it will “never sell your personal information”. Players can create a public profile, and the homepage says you control who sees your Showcase. The App Store label lists contact info as used for the developer’s own marketing.

The iPhone app had no ratings in the US or India stores. The Android app had 3.6 from 140 ratings and 10K+ installs in India, updated on 6 November 2026.

Choose it if you want a generous free tier and a club package with clear published prices. Skip it if you want a long public track record, or a site that has finished its own pricing page.

4. Matcha: ball tracking plus batting and arm-angle numbers

Matcha tracks “the ball, the batter and the bowler” from a phone, according to its App Store listing. It measures ball speed on every delivery, plots line and length on a pitch map and replays the ball’s path in a 3D view. For batters it tracks a beehive, shot type and swing, and the website adds arm angle, foot distance and run-up speed for bowlers. Deliveries are cut into short clips as you go. You set the phone on a tripod behind the stumps. For clubs it adds ball-by-ball scoring, a live stream with the score drawn on the picture, and a match centre with AI win probability and “AI-generated match previews”.

What you pay. The pricing section on Matcha’s homepage lists Free with 50 deliveries a month on one device and one net, with 30 days of storage; Lite at $4.99 a month for 120 deliveries; and Plus at $9.99 a month or $89.99 a year for 300 deliveries. A top-up adds 100 deliveries for $4.99, and the site says top-ups never expire. The US App Store also lists an Individual Monthly plan at $6.99 and a Coach Monthly plan at $59.99, which are not on the homepage. The India App Store shows rupee prices, such as Lite at ₹499 and Plus at ₹999 a month. Count your deliveries: two nets a week of 30 balls each is about 240 deliveries in a four-week month, well beyond Lite.

Data and age. Matcha’s privacy policy (effective 23 August 2026) says “Every player has a public profile page”. For juniors it says that page “never shows date of birth, age, contact details or location, and it is not indexed by search engines”, and it does not let under 13s create an account without a parent or guardian involved. Parents can ask to take a profile off the public web or delete the account. The App Store privacy label, though, says “Data Not Collected”, which does not match a policy that collects a date of birth at sign-up. Read the policy, not the label.

The homepage advertises “4.8 App Rating” and “500+ Active Players”. On 8 November the app had no ratings in the US or India App Stores, and the Android listing showed no rating, with 1K+ installs. The iPhone app was last updated on 8 October 2026.

Choose it if you want batting and bowling numbers in one cheap plan, and you can live with a young product. Skip it if you want a public rating history before you trust the numbers.

5. Clean Bowled: free bowling speed that never leaves the phone

Clean Bowled, from the Australian developer whit., does one job: bowling speed. Its App Store listing says “Clean Bowled actually tracks the ball”, giving the speed of every delivery, the bounce point on a pitch map and a short clip with the ball’s path drawn over the video, “all analyzed on your phone, free, with no subscription”. You put the phone on a tripod behind the bowler’s stumps, with both sets of stumps in frame and the camera at least four metres back, though hand-held filming works too. The listing says that when a capture was hand-held or a bounce point was estimated, the app says so.

The accuracy check. This is the only vendor here that publishes its own comparison with a radar gun. Its site’s field log for 8 September 2026, at outdoor nets with app version 8.1 and the camera 4 metres back, compared the app with a Pocket Radar Ball Coach. 17 of 21 deliveries came within 4 km/h of the radar. On average the app read 2.1 km/h below the radar, with an average error of 2.5 km/h. An earlier session in July, on version 5.0, had an average error of 5.2 km/h over 13 balls. The page is candid about limits: it calls the log “self-reported and not independently verified”, notes that the app reports release speed while a radar catches the ball a moment later, and says the speeds covered were 64 to 85 km/h, so it claims nothing yet about genuine fast bowling. The session header says 27 deliveries while the stats cover 21, which the page does not explain.

What you pay. Nothing. The App Store lists no in-app purchases.

Data and age. The privacy policy (last updated 1 June 2026) says the app has no account system, collects no data and never uploads video, and the App Store label says “Data Not Collected”. Of everything here, this is the simplest choice for a parent filming a junior bowler.

The app needs iOS 18.5 or later, and we found no Android version. It had 5.0 from a single US rating and was updated on 6 November 2026, about five months after release.

Choose it if you want a free, private speed reading at the nets on an iPhone. Skip it if you use Android, or you need batting analysis.

6. str8bat: a bat sensor with an AI coach

str8bat, which gives a Bengaluru office address on its site, sells a sensor that sticks on the bat. Its App Store listing lists 3D shot analysis, bat speed and impact (“swing speed, angle, power, and timing”), sweet spot mapping and an “AI Cricket Coach” that gives “instant feedback and personalized improvement tips”. It works with the str8bat Pro, Classic and Smart Willow sensors. The website gives the vendor’s own figures of “30,000+ players” and “6 million+ shots analysed”. A sensor reads the bat’s movement, not the ball, so it will not tell you where a shot went, only how you swung.

What you pay. You need the sensor first. The website’s store prices load by script and the product pages did not load for us, so we could not read a sensor price; check the str8bat store or an authorised dealer. The app’s subscription prices on the US App Store are Monthly $9.99, Quarterly $38.99 and Yearly $48.00, with limited-time offers at $4.99 a month, $19.00 a quarter and $29.99 a year. Quarterly at $38.99 is close to the yearly price of $48.00, so the yearly plan is the better deal if you intend to keep going. The India App Store lists Monthly ₹199, Quarterly ₹489 and Yearly ₹1,189. We could not find a page that says which app features need the subscription, so ask before buying the hardware.

Data and age. The privacy policy says the website uses Meta Pixel and Google tools to deliver personalised ads and build custom and lookalike audiences, and that str8bat does “not sell your personal data”. The App Store label lists contact details and identifiers as linked to you, and nothing as used for tracking.

The iPhone app had 4.2 from 12 US ratings and 4.8 from 69 India ratings, updated on 17 October 2026. The Android app had 4.8 from 335 ratings and 10K+ installs in India.

Choose it if you are a batter who wants swing numbers in the nets and an app that suggests what to work on. Skip it if you do not want to pay for hardware and a subscription, or you want ball tracking.

Bowling speed claims: what to trust

Speed is the number every bowler wants, and it is the easiest to get wrong. A phone does not measure speed the way a radar does. It estimates where the ball is in each video frame and works out distance over time, so the frame rate, the camera position and the distance it assumes all change the answer.

• Published check: only Clean Bowled publishes app readings next to a radar, ball by ball, and it says the sample is small and self-reported.
• Setup rules: Fulltrack and Clean Bowled both put the camera about 4 metres behind the stumps, and Fulltrack asks for a tripod no taller than 1.3 metres. Move the phone and the numbers move.
• Vendor claims without a method: Ludimos says it measures to the centimetre, and Matcha calls its data pro-level. Neither page we read explains how that was checked.
• Release speed versus later: a radar gun may catch the ball after release, when it has slowed. Clean Bowled says it reports release speed, so its number and a radar’s will not match exactly.

Use one app and one setup every time, and compare yourself with yourself. A 3 km/h gain on the same app and tripod position means more than a big number from a phone held in the stands.

Who sees your player’s video

For a parent this matters more than the stats. Here is what each policy or vendor page says:

• Kept on the phone: Clean Bowled says nothing leaves the device and there is no account.
• Stored in the vendor’s cloud: Fulltrack says video and data are stored in the cloud and shared to other phones. Ludimos and Matcha offer cloud sync and sharing on their plans.
• Public profiles: Matcha gives every player a public profile page, with juniors’ ages and contact details hidden and the page kept out of search engines. Ludimos lets players create a public profile and a Showcase they control. CricHeroes shows players on public scorecards and leaderboards.
• Ages: CricHeroes says users must be 18, or supervised by a guardian. Fulltrack is not intended for under 13s. Ludimos needs verified parental consent under 16. Matcha needs a parent or guardian involved for under 13s.
• Advertising: str8bat’s website uses Meta Pixel and Google ad tools, and CricHeroes says its cookies help deliver advertising. CricHeroes’ App Store label lists usage data as used for tracking.
• Labels that do not match the policy: Matcha’s App Store label says no data is collected, while its policy collects a date of birth.
• Coaches filming a squad: get written permission from parents before filming other people’s children, and check that your plan allows several players. Fulltrack’s Individual plan does not.

What a season costs

Using prices listed on 8 November 2026, here is one year of each camera or sensor option for a single player, ignoring sales and assuming prices hold:

• Clean Bowled: $0, for speed and bounce point only, on an iPhone.
• Ludimos: $0 on the free 300 clips a month, or $59.88 a year on Core at $4.99 a month, plus credit packs if you want AI analysis.
• Matcha: $0 for 50 deliveries a month, $59.88 a year on Lite, or $89.99 a year on Plus.
• Fulltrack AI: the US App Store lists Individual + Yearly at $300.00; check the period on the cheaper Individual items in the app.
• str8bat: the sensor, plus $48.00 a year for the app subscription on the US App Store.
• CricHeroes PRO: $24.99 a year on the US App Store, or ₹399 on the India App Store, with scoring free either way.

A cricket season runs only part of the year in many countries, which is where monthly billing helps. Matcha’s Plus at $9.99 for five summer months is $49.95, less than its $89.99 yearly price.

The non-AI benchmarks

Before paying for any of the six AI apps, compare them with two simpler tools. Neither makes an AI claim, and neither is part of the numbered list above.

StanceBeam Striker: a bat sensor with no subscription (no AI)

StanceBeam Striker, from Quick Logi Technologies in India, is a sensor for the top of the bat grip that measures bat speed, backlift angle, impact and consistency, and its app records about 4 seconds of video per swing with the numbers laid over it. The Striker page lists it at ₹5,299 including taxes as an India-only offer, with “No Subscription”, a 1 year warranty and a 7-day return in India. It claims “>98%” data accuracy validated by IISc Bangalore, which is the vendor’s claim. StanceBeam’s homepage now leads with DRS and cricket simulators, and the iPhone app was last updated on 27 September 2022, with no US ratings. The Android app was updated on 5 February 2026 and had 4.5 from 143 ratings in India.

Choose it if you are in India, use Android and want swing numbers without a monthly fee. Skip it if you use an iPhone, given how long the iOS app has gone without an update.

Bowling speed Meter: mark two frames yourself (no AI)

Bowling speed Meter, from developer Try the Colors, does the sum by hand. You record a delivery, mark the frame where the ball leaves the hand and the frame where it reaches the batter or stumps, enter the distance, and it works out the speed. The listing’s default distance is 20.12 metres, which is 22 yards; set the real distance between the two points you mark, or the answer will be off. The App Store lists Premium purchases at $4.99, $9.99 and $29.99. It had 4.4 from 19 US ratings and 4.3 from 111 India ratings, and was updated on 19 October 2026.

Choose it if you want to check an AI app’s number against your own frame count. Skip it if you want a speed for every ball without any tapping.

What we left out, and why

PitchVision, a net-analysis system that still appears in some cricket tech roundups, could not be checked: on 8 November its address forwarded to a misspelled domain that did not load, and we found no current app. CricVision and Advanced Impactor both market AI shot analysis but had one US rating or none. wellBowled is a manual frame-marking speed app like Bowling speed Meter, with no ratings yet. Speed Gun For Cricket was last updated in February 2023, and SmartCricket BatSense in August 2023. CricClubs and the ECB’s Play-Cricket apps are scoring and league tools with no AI claim. Several new apps with “AI” in the name had no ratings at all. Prediction, fantasy and betting apps, and cricket games, are excluded by design.

How to choose an AI cricket app

Start with the job

A season of scorecards and highlights points to CricHeroes. A bowling speed points to Clean Bowled on an iPhone, or a camera app on Android. Speed plus line, length and batting numbers points to Fulltrack AI, Ludimos or Matcha. Swing numbers for a batter point to a bat sensor such as str8bat, or StanceBeam if you are in India and on Android.

Check your phone and your kit

Clean Bowled needs iOS 18.5 or later. Fulltrack wants 6 stumps and a tripod at 1.3 metres. Most camera apps work best with the phone fixed behind the stumps, so a cheap tripod is part of the cost. A bat sensor needs the sensor, and with str8bat probably a subscription too.

Then the player’s age

For a junior, read the age line first. The rules run from 13 to 18 across these apps. Use a parent’s account where the vendor allows it, keep profiles private or limited to the club, and choose an app that keeps video on the phone if you only need a speed.

Use the free tier before you pay

Clean Bowled is free. Ludimos clips 300 balls a month free, Matcha analyses 50 deliveries a month free, and Fulltrack has a free tier for one batter and one bowler. CricHeroes scoring is free. Run the same net session through two apps and see whether their speeds agree with each other before you trust either.

Do not quote an app speed as fact

If a number is going to a selector, a coach or a social post, say which app and setup it came from. A speed from one app is that app’s estimate. Most of these vendors publish no accuracy method at all.

Verdict

For most club and school cricketers, start with the free tiers: Clean Bowled for a private bowling speed on an iPhone, and Ludimos or Matcha for speed, line and length on either platform. Fulltrack AI adds DRS and has far more Android ratings than the other camera apps, but its single-player and single-device rules matter for coaches. CricHeroes is a free scoring app with 10M+ Android installs in India, and its AI highlights are a bonus rather than a coaching tool. str8bat is the choice for swing numbers if you are happy to buy hardware. None of them replaces a coach watching the player live.
