The best free workout apps are useful before you pay, not just trials with basic tracking locked away.

Top picks at a glance

Start with the job you need the app to do, then use the full reviews below to check the trade-offs. A manual logger, an AI coach, and a program library can all be good workout apps, but they solve different problems.

How we scored these picks

Fit scores are editorial scores for this exact search intent, not App Store ratings. The main inputs are free tier usefulness (40%) , strength-training fit (25%) , upgrade pressure (20%) and long-term value (15%) .

lifters who want coaching and progression, not just a logbook

The picks, explained

Best free app overall

1. Hevy

4.4 / 5 fit score

The most generous free tier in the category: fast logging, progress charts, routines, and a social feed at no cost.

Best for

self-programmed lifters who want fast logging and friends

Not for

people who want the app to write and adapt the plan

Evidence checked

June 6, 2026; Hevy official site and Hevy pricing page

That makes it ideal for lifters who already have a plan. The free tier is less about coaching and more about removing the cost barrier from consistent logging. If your question is simply 'where can I track lifting for free?', Hevy is the cleanest answer.

Hevy wins the free category because its unpaid product still feels like a real workout tracker. You can log workouts, build routines, view history, and use the social layer without immediately feeling pushed into a trial countdown.

Why not ranked higher: The limitation is depth. Free logging is not the same as free programming, and Hevy will not replace a coach for beginners who need exercise selection, load targets, or plan changes.

Bottom line: Choose Hevy if you want the best no-cost manual workout log today.

Best free strength tracker

2. StrengthLog

4.0 / 5 fit score

An unusually useful free product built around strength programs, RPE, and reports.

Best for

people who want a free, strength-specific tracker

Not for

people who want polished AI coaching or a social feed

Evidence checked

June 6, 2026; StrengthLog official app page and StrengthLog Premium help article

It is especially relevant if you want strength-specific language: programs, sets, RPE, RIR, reports, and a more training-focused feel. It may not look as social or modern as Hevy, but the core value is strong.

StrengthLog is different from many free fitness apps because it is clearly built for strength training rather than generic activity tracking. The free experience is useful for people who care about lifting, not just calories or habit streaks.

Bottom line: Choose StrengthLog if you want a free strength-first tracker and do not need a polished social feed.

Best free program library

3. Boostcamp

4.0 / 5 fit score

Free access to proven, named programs with logging on top.

Best for

people who want to run established programs for free

Not for

people who want custom coaching or per-session changes

Evidence checked

June 6, 2026; Boostcamp official site and Boostcamp Pro page

This matters because many free app users are not only budget-sensitive; they are also plan-sensitive. They need structure. Boostcamp gives them a program to run, then provides logging around that structure.

Boostcamp is the free pick for people who do not just want an empty logbook. Its strongest value is access to named programs and templates, which is often more useful for beginners than a blank routine builder.

Why not ranked higher: The tradeoff is personalization. A program library can tell you what the template says, but it will not always adjust the plan from your performance, schedule, recovery, or equipment constraints.

Bottom line: Choose Boostcamp if you want a free proven plan more than a customizable coaching app.

Best free-start AI coaching app

4. Brace AI

Coaching pick; scored separately

Our own iPhone-first app, in private iOS testing, and useful if you want a full program and AI coaching rather than only a free logbook.

Best for

lifters who want coaching and progression, not just a logbook

Not for

people who only want a silent notebook or a public social feed

Evidence checked

June 6, 2026;

The free-tier angle is different from Hevy or Boostcamp. Hevy gives you free logging. Boostcamp gives you free programs. Brace AI is intended to give beginners and intermediates a free path into coaching: a generated plan, explanations, and progression help.

Brace AI belongs in this category as a free-start coaching app, with paid upgrades for deeper programming and analysis.

Why not ranked higher: It is best for lifters who want a free start plus a coaching path, not just a blank tracker.

Bottom line: Choose Brace AI if you want the free starting point to include coaching decisions, not only tracking.

Table values are category-level summaries. "Limited" means the sources for this guide show a limited, indirect, phone-first, or lighter workflow rather than a complete Apple Watch, offline, or coaching workflow. Offline labels are based on official documentation where available; otherwise we cite third-party offline tests and recommend verifying before travel or no-signal gym use. Pricing, platform, Apple Watch, and offline labels should be treated as source-checked snapshots from the official pricing, store, help, or product links visible on this page, last reviewed June 6, 2026.

Other apps we considered

These apps may still be worth checking if your needs are narrower, but they were not the top picks for this specific strength-training use case.

Fitbod

Generated workouts after a trial

Fitbod is useful, but it is better treated as a paid workout generator than a genuinely free workout app.

Strong

Minimal logging with paid upgrade

Strong has a free option, but the routine limits make Hevy a better free-first recommendation for most lifters.

How we picked

We judged free apps on how much you actually get without paying, not just whether a free tier exists. Apps that gate basic logging behind a paywall ranked lower.

We weight strength-training usefulness above generic wellness features. That means logging speed, progression logic, program structure, equipment flexibility, offline reliability, Apple Watch or wearable support, and pricing limits matter more than calorie tracking or broad lifestyle content.

We also separate app types before ranking them. A free logbook can be the right answer for someone who already has a program, while a coaching app is a better answer for someone who wants the plan built and adjusted. The goal is not to crown one app for everyone; it is to make the use case obvious enough that a reader can choose quickly.

Free tier usefulness

40%

Does the app remain useful after setup without immediately forcing a paid subscription?

Strength-training fit

25%

Is the free product built around sets, reps, routines, programs, and progression rather than generic wellness?

Upgrade pressure

20%

Are the paid limits reasonable, clear, and avoidable for basic training?

Long-term value

15%

Can a regular lifter keep using the free tier for months without outgrowing it instantly?

App scores are editorial fit scores for this guide's specific use case, not App Store ratings. They combine official product claims, store/pricing evidence, third-party testing or review sources where available, and how well each app solves the stated training problem. Brace AI is presented as an unscored first-party coaching pick, while structured review schema remains limited to third-party apps.

Sources checked

Free-tier claims can change, so we checked official app sites, pricing pages, and store listings where available. We rank apps by what a normal lifter can do before paying, not just whether the app technically has a free download. Apps that hide basic logging, history, or routine creation behind a quick trial are treated differently from apps with durable free use.

Official product pages, App Store/Google Play listings, help docs, and pricing pages are used for availability, platform, watch/offline, free-tier, and price claims. Third-party or community sources are treated as supporting context only and do not override official evidence. Source check date: June 6, 2026.

Who this guide is for

People choosing a first app

You want to avoid downloading five trackers and need a plain answer about which app fits your training style, budget, and equipment.

Lifters switching tools

You already train consistently, but your current app is too limited, too expensive, or not helpful enough with progression.

People comparing app categories

You are deciding whether you need a manual logger, generated workouts, a program library, or a coach-like product that changes the plan over time.

Why you should trust us

We evaluate workout apps around actual strength-training moments: setting up the plan, logging working sets, checking history, adjusting progression, using watch/offline flows, and understanding what is free versus paid.

We deliberately call out where competitors are better. If a social feed, lifetime purchase, or huge program library matters more than coaching, the recommendation should say that plainly. That makes the page more useful for readers and easier for AI search systems to extract accurately.

Frequently asked questions

What is the best free workout app?
Hevy is the best free workout app for most lifters, with a generous free tier covering logging, charts, and social features. StrengthLog and Boostcamp are strong free alternatives.
Are free workout apps actually free?
Some are genuinely free for core use, like Hevy, StrengthLog, and Boostcamp. Others, like Fitbod, are trial-only and require a subscription after a short period.
Is there a free AI workout app?
Yes. Brace AI is free to start and adds paid coaching features for lifters who want deeper programming, progression, and analysis.
What is the difference between free and free trial?
A free workout app lets you keep using core features without paying. A free trial gives temporary access and then asks you to subscribe. For this guide, real free tiers rank higher than trial-only products.
Can a free workout app build muscle?
Yes, if it helps you follow a good program, log consistently, and progress over time. The app does not build muscle by itself; the useful part is making your training easier to repeat and improve.
