Boostcamp vs Hevy vs Liftosaur (2026): Programs, Pricing, Verdict

Boostcamp, Hevy and Liftosaur all log your sets. That is where the overlap ends.

Each one answers a different question. Boostcamp asks which program do you want to run? and hands you a free library of them. Hevy asks what did you lift today? and makes logging it fast and cheap. Liftosaur asks how exactly should your weights progress? and lets you write the rule yourself, in a small scripting language.

So the right pick depends less on features and more on who writes your program: a coach, you, or you with code. Every price, limit and rating below was checked against the App Store, Google Play or the company’s own pages in September 2026.

The short answer

Pick Boostcamp if you want to follow a proven program (nSuns, GZCLP, 5/3/1, PHUL) with auto-progression, free. Pick Hevy if you write your own routines and want the cheapest capable logger: Pro is $23.99/year or $74.99 lifetime. Pick Liftosaur if you want to define exactly how every lift progresses, in code. Its premium is $39.99/year.¹²³

Boostcamp vs Hevy vs Liftosaur: what’s the real difference?

The difference is who writes the program. Boostcamp gives you someone else’s: 11,000+ programs, including named coach programs, with the weights calculated for you. Hevy assumes you write your own and makes logging fast. Liftosaur lets you write the program and its progression logic as text, so the app knows exactly what to load next.¹²³

Think of it as three layers of the same job:

Choosing the program. Boostcamp’s whole value is here. Its listing names nSuns, GZCLP, 5/3/1 BBB, PHUL, PHAT, Reddit PPL and programs from coaches including Eric Helms, Greg Nuckols, Alex Bromley and Jonnie Candito.¹
Progressing the program. Liftosaur’s whole value is here. You write a line like Squat / 2x5, 1x5+ / 45lb / progress: lp(5lb) and the app runs that rule for you, session after session.²
Logging what happened. Hevy’s whole value is here: a fast logger, a social feed, a low price and the biggest install base of the three.³¹¹

All three log sets, reps and weight, and all three can record effort (RPE). The question is which layer you want the app to own.

Hevy vs Boostcamp: which is better?

Boostcamp is better if you want to follow an established program, because the library and auto-progression are free. Hevy is better if you already have your own routine and want a quicker, cheaper, more social logger with a real Apple Watch app. For beginners who don’t have a program yet, Boostcamp gets you training on a proven plan faster.¹⁴³

The free tiers point in opposite directions. Boostcamp’s free plan includes the program library, the full tracker and a custom program builder with no cap.⁴ Hevy’s free plan logs unlimited workouts but caps you at four saved routines and seven custom exercises, with three months of graph history.⁵⁶

So a free Boostcamp user can run a four-day nSuns block without paying. A free Hevy user can log that block too, but must set it up by hand, and Hevy won’t calculate the next session’s weights unless they pay for Pro and use Hevy Trainer.⁸

Where Hevy wins:

Price. $23.99/year against Boostcamp’s $59.99/year, and Hevy is the only one of the two with a lifetime option ($74.99).⁴³
Watch and Android wearables. Hevy has an Apple Watch app and a Wear OS app.³¹¹ Boostcamp’s App Store listing shows no Watch app.¹
Scale. 95K App Store ratings and 5M+ Google Play installs, against Boostcamp’s 10K ratings and 500K+ installs.¹⁰³¹¹

Where Boostcamp wins:

Programs. A searchable library of named programs you start with one tap, versus building routines yourself.
Progression on the free tier. “Auto-progression sets your next weights,” per its listing, without a subscription.¹
Analytics that fit programs. Pro adds a Strength Score (0–100 across the big lifts) and a per-muscle volume heatmap.⁴

Our Hevy vs Strong comparison covers the other big “just log it” choice if you have ruled Boostcamp out.

Hevy vs Liftosaur: which is better?

Hevy is better for almost everyone who just wants to log workouts: it’s cheaper, simpler and has roughly 240 times more App Store ratings. Liftosaur is better if you want total control over progression, deloads and AMRAP logic, and don’t mind learning a small scripting language. Its own developer says some Liftoscript is “required to use Liftosaur effectively.”²⁹³

Liftosaur calls itself “the only scriptable workout app.”² Its homepage pitch is “It’s like having Google Sheets and Strong in the same app!”⁷ That is accurate. You describe a program in Liftoscript, and the app applies the progression each time you finish a session. That includes linear and double progression, myo-reps and RPE-based sets.¹³

Anton Astashov, Liftosaur’s developer, stopped hiding that complexity in August 2026. He wrote in the changelog: “I just need to be honest and upfront that knowing at least some Liftoscript basics is required to use Liftosaur effectively.”⁹ That candor is the most useful sentence in this comparison. If the idea of editing a line of code between sets sounds tedious, Liftosaur isn’t for you.

What else sets it apart:

Open source. The code is public on GitHub under the AGPL-3.0 license.⁷
Free core. Premium adds only graphs, week insights, a plate calculator and push notifications; “the rest is free.”⁷
AI access, for Premium users. Since March 2026 Liftosaur has an MCP server and REST API. You can connect Claude, ChatGPT or Gemini to create programs, tweak progressions and log workouts. Both need Premium.⁹
Apple Watch, for Premium users. The Watch app arrived in 2026 and needs a Premium subscription. It can complete sets and run rest timers, but not edit the workout.⁹

Hevy’s answer to “tell me what to lift next” is Hevy Trainer, a Pro feature that “automatically adjusts your working weights.”⁸ It’s a fixed rule you configure, not a rule you write. For most lifters that is enough.

How much do Boostcamp Pro, Hevy Pro and Liftosaur Premium cost in 2026?

Hevy is cheapest: Hevy Pro (sometimes called Hevy Premium) costs $2.99/month, $23.99/year or $74.99 lifetime. Liftosaur Premium is $4.99/month, $39.99/year or $99.99 lifetime. Boostcamp Pro is $59.99/year with a 7-day trial, or $14.99/month with no trial. Boostcamp’s annual plan saves about 67% over monthly. Only Hevy and Liftosaur sell a lifetime option.⁴²³

Plan	Boostcamp Pro	Hevy Pro	Liftosaur Premium
Monthly	$14.99⁴	$2.99 ($3.99 SKU also listed³)	$4.99²
Yearly	$59.99 (7-day free trial⁴)	$23.99³	$39.99²
Lifetime	Not offered	$74.99³	$99.99²

Boostcamp says its pricing “is the same across iOS and Android.”⁴ Its App Store listing also shows other Pro SKUs ($11.99 to $79.99) and a limited-time $48.99 offer.¹

What does each cost over three years?

Over 3 years	Boostcamp	Hevy	Liftosaur
Free tier only	$0	$0	$0
Paying yearly	$179.97	$71.97	$119.97
Lifetime	—	$74.99	$99.99
Paying monthly	$539.64	$107.64	$179.64

The key fact for Boostcamp is that most people never need to pay. The library, tracker and auto-progression are free. Pro is for the Strength Score, the volume heatmap, 20+ exclusive coach programs and personalized programs.⁴

Which app is best for powerlifting, powerbuilding and bodybuilding?

For powerlifting and powerbuilding, Boostcamp has the deepest bench of ready-made programs (5/3/1, nSuns, Candito, GZCLP) and Liftosaur gives the most control over peaking and training-max waves. For bodybuilding, any of the three works; what matters is tracking weekly sets per muscle, which Hevy shows free, Liftosaur shows per program and Boostcamp shows on Pro.⁴²⁷⁶¹⁴

The research is useful here because the goals really do diverge. A 2026 meta-regression by Pelland and colleagues analysed 67 studies and 2,058 participants. More weekly volume increased both muscle size and strength, with diminishing returns that were sharper for strength. Training frequency helped strength but had a negligible effect on hypertrophy.¹⁴

In practice:

Hypertrophy / bodybuilding. Count hard sets per muscle per week. Schoenfeld’s 2017 meta-analysis found each additional weekly set was associated with roughly 0.37% more muscle growth.¹⁵ Hevy shows set count per muscle group on its free plan, Liftosaur shows weekly volume per muscle group for your program against what you actually did, and Boostcamp Pro adds a per-muscle volume heatmap.⁴⁷⁶
Strength / powerlifting. Structure matters more. Williams and colleagues’ 2017 meta-analysis found periodized programs produced larger one-rep-max gains than non-periodized ones (effect size 0.43).¹⁶ A 2022 update by Moesgaard’s group at the University of Copenhagen confirmed the strength advantage (effect size 0.31) and found no difference for hypertrophy.¹⁷
Powerbuilding. You want both, which is why ready-made hybrid programs like PHUL and PHAT are popular. Boostcamp hosts both; on Hevy or Liftosaur you build them yourself.¹ Ladder takes a third route: a human coach writes each week’s plan for a team, so you pick a team rather than a split (see our Ladder app review).

So “which app for powerlifting” really means “which app makes periodization easiest to follow.” Boostcamp wins if you want someone else’s periodization. Liftosaur wins if you want to write your own.

Which tracks progressive overload and RPE best?

All three log RPE. Boostcamp logs RPE, RIR and estimated 1RM on the free tier and auto-progresses its programs. Liftosaur can change weight, reps or sets based on your logged RPE, because progression is scripted. Hevy logs RPE once you switch it on, but automatic weight changes come only through Hevy Trainer on Pro.¹²⁸¹⁸

That matters because RPE-based loading is a real method, not a gimmick. In a 2018 study led by Eric Helms, trained lifters used either RPE-based or percentage-based loading for eight weeks. The authors concluded: “Both loading-types are effective. However, RPE-based loading may provide a small 1RM strength advantage in a majority of individuals.”¹⁹ A 2022 meta-analysis by Hickmott and colleagues was more cautious. It found that autoregulated and standardized loading “produced similar improvements in strength.”²⁰

The honest reading: autoregulation helps some lifters a little, and it never hurts. The bigger win is having a progression rule and sticking to it.

Dr. Eric Helms explains that “autoregulation is simply a systematic approach to implementing something every trainer worth their salt knows is of supreme importance: the principle of individuality.” He is a research fellow at Auckland University of Technology and lead author of a 2016 paper on applying the RIR-based RPE scale.²¹²² Disclosure: Helms is listed as an advisor to Boostcamp, and his programs appear in its library.¹²³

Dr. Michael Zourdos, of Florida Atlantic University and co-developer of the RIR scale, makes the same point from the other side. “Various progressive overload strategies can maximize short-term gains in novice trainees,” he writes, and his practical advice is to “pick a strategy, believe in it, and stick with it for at least a little bit.”²⁴

That is the case for Boostcamp for beginners and for Liftosaur for tinkerers: both force you to commit to a rule. Our guide to AI-automated progressive overload goes deeper on how apps decide your next weight.

Boostcamp vs Hevy vs Liftosaur: data tracking differences

Tracking feature	Boostcamp	Hevy	Liftosaur
RPE logging	Free, plus RIR¹⁴	Yes, switched on in settings¹⁸	Yes, and it can drive progression²
Estimated 1RM	Free¹	Projected 1RM per exercise⁶	1RM-percentage loading⁷
Graph history	—	3 months free; all-time on Pro⁶	Graphs are Premium⁷
Sets per muscle group	Volume heatmap on Pro⁴	Set count per muscle, free⁶	Weekly volume per muscle, free; graphs on Premium⁷
Apple Health	Syncs bodyweight and workouts¹	Exports workouts³	—
API / AI assistant access	—	Free ChatGPT app²⁵; public API on Pro²⁶	MCP server + REST API, Premium only⁹

A dash means the app’s own listing and pages don’t state it either way.

Which is best for beginners?

Boostcamp is the best of the three for most beginners. It is free, and starting a proven beginner program such as GZCLP or Greg Nuckols’ beginner program takes one tap. Hevy suits beginners who already have a routine from a coach or friend. Liftosaur is the worst fit for beginners, because it needs some scripting.¹⁹

A beginner’s biggest risk isn’t picking the “wrong” app. It’s picking no program at all and wandering between machines. Boostcamp removes that risk for free. Hevy’s free tier works too, but you have to bring the plan, and four saved routines is tight if you run an upper/lower plus accessories split.⁵

Beginners do not need Liftosaur’s power. Its own developer is clear that learning Liftoscript is part of the deal.⁹

Gravl vs Hevy, and where do Strong and Fitbod fit?

Gravl and Fitbod generate workouts for you algorithmically, and each costs about $60–$96 a year. Strong is a pure logger closest to Hevy. SensAI is a conversational AI coach that writes and adjusts your program. None of these runs a named community program the way Boostcamp does.²⁷²⁸²⁹³⁰

App	Best for	Paid price (US)	Free option	App Store rating
Boostcamp	Following proven programs	$59.99/yr, $14.99/mo⁴	Library + tracker free	4.8 (10K¹)
Hevy	Cheap, social logging	$23.99/yr, $74.99 lifetime³	Yes, 4 routines	4.9 (95K³)
Liftosaur	Scripted progressions	$39.99/yr, $99.99 lifetime²	Yes, core free	4.9 (395²)
Gravl	AI-prescribed sessions	$14.99/mo; yearly $59.99–$89.99²⁷	Free to start	4.9 (5.5K²⁷)
Strong	Fast, watch-first logging	$4.99/mo, $29.99/yr, $99.99 forever²⁸	Yes, 3 routines	4.9 (109K²⁸)
Fitbod	Algorithmic workouts	$15.99/mo, $95.99/yr²⁹	Trial	4.8 (286K²⁹)
SensAI	Conversational AI coach	$6.99/mo, $69.99/yr³⁰	7-day free trial³⁰	4.6 (34³⁰)

Gravl vs Hevy: Gravl “estimates your one-rep max from your logged history and prescribes the next session from it.” You rate a set Easy or Hard, and the next prescription adjusts.²⁷ Hevy leaves the programming to you unless you pay for Trainer. Pick Gravl if you want to be told what to lift; pick Hevy if you want to log what you chose.

Boostcamp vs Hevy vs Strong: Strong is a logger, closest to Hevy. Its free version is limited to three custom routines, and Strong PRO costs $29.99/year or $99.99 forever, against Hevy’s $23.99/year or $74.99 lifetime.³²⁸ Like Hevy, it has an Apple Watch app and no program library. If you want programs written for you, Boostcamp is still the one of the three that does it.

Boostcamp vs Fitbod: Fitbod builds each workout for you from its exercise library.²⁹ Boostcamp gives you a fixed, named program. Pick Fitbod for variety decided for you, Boostcamp for a structured block. Our Fitbod review covers what its subscription buys.

SensAI, disclosed because it’s ours, sits between a program library and a human coach. You tell the SensAI coach your goals, equipment and schedule. It writes the program and rewrites it when you say “my shoulder is sore, change this week.” It also factors in the Apple Health data you choose to share: workouts from your watch app, sleep and resting heart rate, and HRV from Apple Watch.³¹

Garmin, Oura, WHOOP, COROS and Polar workouts reach SensAI through Apple Health. Their HRV and proprietary scores (Body Battery, Readiness, Recovery) do not.³¹ Setup lives in our Help Center: how to connect your wearable to SensAI through Apple Health.

The trade-offs are real. SensAI is iOS-only (iPhone and Apple Watch, no Android), has no permanent free tier, and its rating rests on only 34 reviews. It won’t run nSuns for you the way Boostcamp does. Our SensAI review covers where it falls short.

Who should pick Boostcamp, Hevy or Liftosaur?

Pick Boostcamp to follow a proven program for free. Pick Hevy for the cheapest, most social logger with a real Apple Watch app. Pick Liftosaur if you want to program your own progression and enjoy tinkering. If you want the program written and adjusted around your recovery, none of the three does that on its own.¹²³

Choose Boostcamp if you:

Want to run nSuns, GZCLP, 5/3/1, PHUL, PHAT or a named coach’s program
Want the next session’s weights calculated without paying
Train mostly from your phone and don’t need a Watch app

Choose Hevy if you:

Already know your routine and just need to log it fast
Want an Apple Watch or Wear OS app
Want the cheapest paid tier, or a $74.99 lifetime option
Like a social feed of friends’ workouts

Choose Liftosaur if you:

Want to define exactly how each lift progresses, deloads and resets
Are comfortable reading and editing a line of code
Value open source and API/MCP access to your own data

Consider none of them if what you want is a program that adapts to your feedback and recovery without writing it yourself. That is where an AI coach fits. Our roundup of the best AI personal trainer apps compares the options, SensAI included. If you’re weighing another coach-plus-app model, see Hevy vs Caliber and our Ladder app review.

Frequently asked questions

Is Boostcamp better than Hevy?

Boostcamp is better for following established programs, because its program library and auto-progression are free. Hevy is better as a logger: it’s cheaper ($23.99/year vs $59.99/year), has a lifetime option and offers Apple Watch and Wear OS apps. Boostcamp’s App Store listing shows no Watch app.¹⁴³

Is Boostcamp free?

Yes, for most people. The free plan includes 11,000+ programs, the full tracker with RPE and RIR logging, a plate calculator, PRs, estimated 1RM and a custom program builder with no cap. Boostcamp Pro ($59.99/year or $14.99/month) adds a Strength Score, a volume heatmap, 20+ exclusive coach programs and personalized programs.⁴

Is Liftosaur free?

Mostly. Liftosaur’s own documentation lists graphs, week insights, the plate calculator and push notifications as premium features, and says “the rest is free.” Premium is $4.99/month, $39.99/year or $99.99 lifetime. The Apple Watch app and the MCP server/API also need Premium.²⁷⁹

Is Boostcamp Pro or Hevy Pro (Premium) worth it?

Hevy Pro is worth it if you need more than four routines or all-time graphs, or want Hevy Trainer to set your weights. At $23.99/year it’s the cheapest upgrade here. Boostcamp Pro is only worth it if you want its Strength Score, per-muscle heatmap or exclusive programs. The core program library is already free.⁴³⁵

Does Boostcamp work with Apple Watch?

Boostcamp’s App Store listing lists iPhone, iPad and Apple Vision, with no Apple Watch app, as of September 2026. It does sync bodyweight and workouts with Apple Health. Hevy and Liftosaur (Premium) both have Apple Watch apps.¹⁹³

Does Boostcamp have an AI coach?

Yes. Boostcamp’s listing describes an “AI Coach” that asks a short questionnaire and builds “a customized multi-week program.” A March 2026 update added creating programs with AI. Hevy has a Hevy app for ChatGPT that is free for all Hevy users, and Liftosaur Premium connects to AI assistants through an MCP server.¹⁹²⁵

Is Liftosaur open source?

Yes. Liftosaur’s code is on GitHub under the AGPL-3.0 license, maintained by developer Anton Astashov. The project describes itself as a “weightlifting tracker app for coders.”⁷

Who makes Boostcamp?

Boostcamp is made by BPM Health Co. Co-founders Patricia Wong and Michael Liu describe themselves as “college friends and Canadians now living in Brooklyn, NY.” Dr. Eric Helms is listed as an advisor.¹²³

The bottom line

Boostcamp, Hevy and Liftosaur aren’t really rivals. They own different parts of the same job.

Boostcamp picks the program for you, free. Hevy logs whatever program you already have, cheaply and socially. Liftosaur runs whatever progression you can describe, if you’ll learn a little code to describe it.

The research says the app matters less than the commitment. Periodized, structured training beats winging it for strength, and more weekly sets build more muscle.¹⁶¹⁴ So pick the app that makes it easiest for you to follow one plan for twelve weeks. If you’d rather have that plan written and adjusted for you, that’s the job SensAI was built to do.
