It is week six of a meet prep. Your top single felt like a grinder, you slept five hours, and your two-year-old spreadsheet just adds 5kg because that is what the next cell says. A good powerlifting app should do better: read how the session went, then change tomorrow before tomorrow breaks you.
This guide looks at the apps lifters keep recommending for the squat, bench and deadlift, and asks whether the smart part is real autoregulation or just a progression formula with a marketing badge.

What “AI” really means in a powerlifting app
Most powerlifting “AI” is not a large language model. It is autoregulation: a rules engine that takes your readiness and the RPE or RIR you log, then adjusts load and volume. That is genuinely useful, and it is closer to what a thoughtful coach does than a fixed percentage chart.
Hold two ideas apart. Progression adds weight on a schedule, and almost every tracker does it. Autoregulation changes the prescription based on what your body reported today. An app can also have full RPE fields and zero autoregulation, so the real question is whether tomorrow’s session changes because you logged an RPE 9.5 on a planned RPE 8.
JuggernautAI: the closest thing to a coach in your pocket
Price: $34.99/mo or $349.99/yr, with 2 weeks free | Platforms: iOS, Android
Best for: Competitive powerlifters who log honestly.
JuggernautAI, from Chad Wesley Smith and Juggernaut Training Systems, is the app serious powerlifters tend to name first. You set up your competition lifts, your weak points and your training age, then log weights, reps, RPE and RIR while the app adjusts load and volume. Across a block, it builds toward a peak, which is the part generic apps fumble.
Each session starts with how ready you feel, and if you overshoot your target RPE early it can cut a set so you do not bury yourself. Sessions often run 45 to 90 minutes, which is the point for a competitive lifter and a deterrent for a casual one. A newer lifter can use it too, but should expect the first block to feel slightly off while their sense of RPE and the app learn each other.
What it does well:
- True RPE and readiness autoregulation
- Blocks built toward a meet
- A fraction of the cost of a remote coach
Where it falls short: it is only as good as your honesty. Sandbag your RPE and the algorithm chases bad data. Sessions can also run long, so it suits lifters with time to train.

RP Hypertrophy: powerbuilding volume
Price: $34.99/mo, or $24.99/mo billed at $299.99 a year, with a 30-day money-back guarantee
Best for: Lifters building strength on a base of muscle.
The RP Hypertrophy app, built on Dr. Mike Israetel’s principles, is the strongest pick if your strength goals ride on more muscle. You log pump, soreness and performance, and the app decides whether to add sets, hold or back off across a training block.
If your goal is to be bigger and stronger across the year with the occasional meet, it is one of the better options, because its programming traces back to published volume and recovery research rather than gym lore. It is good at deciding whether your back can take another set of rows. It is less interested in walking your squat single up to a meet attempt.
What it does well:
- Week-by-week volume decisions
- A large template library, or build your own
- Programming rooted in published volume and recovery research
Where it falls short: it is built for hypertrophy first, so it is not a dedicated meet peaking engine. If a meet total is your only goal, look at JuggernautAI.
Boostcamp: the best free library for lifters who can program
Price: Free for programs and tracking, with an optional Pro tier | Platforms: iOS, Android
Best for: Self-directed lifters who want proven templates.
Boostcamp says there is “no paywall on programs”, and its library includes well-known strength programs and coach-designed routines. It tracks sets, reps, weight and RPE, and fills in your next weights so you are not doing math between sets.
For the price, it is hard to argue with. Running a proven program honestly will out-progress most lifters who keep hopping between apps looking for the perfect algorithm, and a clean tracker around a good template is all many lifters actually need.
What it does well:
- A deep library of programs for free
- Automatic progression within a program
- A custom builder for your own plan
Where it falls short: it progresses templates rather than rewriting your week, so it trusts you to pick a program and adjust when life gets in the way.
Liftosaur: total control for lifters who script their own logic
Price: Free to start, with a paid upgrade. Confirm on its site | Platforms: iOS, Android
Best for: Lifters who want explicit control over every rule.
Liftosaur is the opposite of a black box. It is built around Liftoscript, a plain-text language where you write your own program and progression rules, using percentages or RPE. If you have ever added formulas to a training spreadsheet for fun, this is for you.
There is a real audience for this, often engineers and longtime lifters who treat their programming like code they want to refine. Nothing else on this list gives you this much say over how a program behaves when you hit or miss your numbers.
What it does well:
- Any progression logic you can express
- Myo-reps, drop sets and custom timers
- Programs you can refine like code
Where it falls short: the learning curve is steep. If you do not want to write logic, it will feel like homework.
Hevy: the best plain logger when you bring your own program
Price: Free, Pro from $2.99/mo or $23.99/yr in the US | Platforms: iOS, Android, web
Best for: Lifters who already have a plan and want fast logging.
Sometimes the simplest move is the smartest. Hevy is a clean, fast logger for sets, weight, reps and RPE, with PRs, estimated one-rep max and progress graphs. It pairs well with a coach or a spreadsheet.
Many strong lifters need exactly this. If a coach writes your program, you do not want an app second-guessing them, you want somewhere fast to record the work. Hevy also says more than 17 million athletes use it, so it is easy to find training partners there.
What it does well:
- Fast logging with almost no friction
- Good free tier with unlimited workouts
- Clear PR and progress tracking
Where it falls short: it does not program for you or autoregulate. It is a very good notebook rather than a coach.

RIRLift: free reps-in-reserve load calls
Price: Free, Pro $9.99/mo or $79.99/yr (US) | Platforms: iPhone, Apple Watch
Best for: iPhone lifters who bring their own plan and want the next load set for them.
RIRLift is built around the same signal powerlifters use to judge effort: how many reps you had left. Log weight, reps and reps in reserve, and its Coach sets the next load and explains the number. There is no account to create.
That makes it an easy way to add some autoregulation to a program you already follow, without paying or signing up. The free plan covers unlimited workouts, 4 active routines and Coach loads, and Pro adds more Coach conversations, unlimited routines and all-time analytics.
What it does well:
- Autoregulated next loads on the free plan
- A full session on Apple Watch
- Imports your history from Hevy, Strong or FitNotes
Where it falls short: it is a general lifting tracker rather than a powerlifting specialist, so it will not plan a meet peak, and Android is still on a waitlist.
What a year costs
| App | Free version | Paid, per year | Pay for it if |
|---|---|---|---|
| JuggernautAI | 2-week trial | $349.99 | You have a meet coming and will log honestly |
| RP Hypertrophy | 30-day money-back | $299.99 | Size is the base of your strength plan |
| Boostcamp | Programs and tracking | Optional Pro | You want extra analytics |
| Liftosaur | Yes | Optional upgrade | You use it enough to want the extras |
| Hevy | Unlimited workouts, 4 routines | Pro from $23.99 | You want unlimited routines and full stats |
| RIRLift | Unlimited workouts, 4 routines | Pro $79.99 (US) | You lean on Coach and want full analytics |
The price gap between the free and paid ends of this table is large, and so is the difference in what you get. A paid autoregulating app makes sense when your training is serious enough that a bad block costs you something. Otherwise, a free program run honestly is hard to beat.
How to rate RPE honestly
Every autoregulating app here depends on the number you give it, and most lifters are off for the first year or two. A few habits close the gap:
- Think in reps left. RPE 8 means you had about two more good reps, and RPE 9 means one. That is easier to judge than a feeling.
- Check yourself occasionally. Film a set you rated, or take a safe set closer to failure now and then, to see whether your estimate holds up.
- Rate the set you did, not the one you planned. A planned RPE 8 that flew up is not an RPE 8.
- Do not sandbag. Rating sets easier or harder to get a nicer session only feeds the app bad data.
If you are new to RPE, spend a block logging it before you trust an app to act on it.
Questions to ask before you pay
- Does tomorrow change because of what I logged today? If not, it is progression rather than autoregulation.
- Does it know my meet date? Only some apps can build a peak.
- Can I bring my own program? Some apps insist on writing it for you.
- What happens to my data if I leave? Check for exports before you build a year of history.
- Is there a real trial? A block is the fair test, so see how far the trial gets you.
A lean way to start
- Download Boostcamp and Hevy first. Both are free, and they show you whether you want template-and-log or full programming.
- Run a known free program for two weeks while logging honest RPE on every working set.
- If a fixed plan feels too rigid, start a JuggernautAI trial and let it autoregulate a block, or add RIRLift for free load calls.
- If you want to tweak every rule, move to Liftosaur and script your own.
- Pay only for the one that matches how you train, and cancel the rest before the next billing cycle.
What these apps still cannot do
An app is not a coach. Even the best autoregulation is a rules engine, not a person who can watch your bar path. None of these tools can diagnose a tweaked back or fix a technique fault from a number, and RPE-based adjustment assumes you can rate effort accurately, which takes most lifters a year or two.
These apps do not give medical advice. If you have pain that is sharp, persistent or radiating, see a qualified physician or physical therapist.
Verdict
For meet prep and true autoregulation, JuggernautAI is the pick. For free programs, start with Boostcamp, and add RIRLift on iPhone if you want free load calls. RP Hypertrophy suits powerbuilders, Liftosaur suits lifters who enjoy building the system, and Hevy is the right call when you already have a plan.
