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.

The picks, explained

Free logging with social sharing

1. Hevy

Free workout logging, charts, routines, and social features, with limits expanded by Pro.

Best for

lifters who want free social logging or paid Pro Trainer planning

Not for

people who want Trainer-level planning and progression without a Pro subscription

Product references

Hevy Trainer announcement

Consider the free logger when you already have a plan to record. Generated programs and performance-based weight adjustments belong to Pro Trainer, not the free logging offer.

Hevy documents an ongoing free logging tier with routines and sharing, separate from Pro Trainer. Its help documents four free routines, seven custom exercises, and 30-day or three-month statistics views. Check whether these limits meet your needs before choosing it over another free logger.

Why not ranked higher: Free logging is not free Trainer access. Hevy's announcement says Trainer is included in Pro and supports generated programs and performance-based weight adjustments. Check the current local Pro offer and free limits before choosing a tier.

Bottom line: Shortlist Hevy for free logging and sharing, then check its current limits against the routines and history you need.

Before you subscribe

Check price, free-tier limits, and device requirements at Hevy Trainer announcement. A watch app does not necessarily work without a phone or an internet connection. Try saving a short workout and syncing it on your own devices before relying on offline use.

Strengths

  • Free logging alongside paid Trainer planning
  • Trainer generates personalized programs and adjusts weights from performance
  • Social feed and following

Watch-outs

  • Trainer and its planning guidance are Pro features
  • The core logger still assumes you know which workflow you want

Best free strength tracker

2. StrengthLog

Free strength logging and program options, with training reports in Premium.

Best for

people who want a free, strength-specific tracker

Not for

people who want polished AI coaching or a social feed

Product references

StrengthLog official app page and StrengthLog Apple Watch guide

StrengthLog offers free logging, basic statistics, and program options. RPE/RIR logging, detailed reports, and the full program catalog require Premium. Compare those boundaries before choosing it for effort tracking or analytics.

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

Free access to named programs, logging, and auto-progression.

Best for

people who want named programs or manual custom plans with free core logging

Not for

people who need demonstrated conversational coaching or a verified phone-free workflow

Product references

Boostcamp official site and Boostcamp Pro page

Boostcamp's free core includes program access, logging, performance-based auto-progression, and unlimited manual custom program building. You can follow a library program or build your own multi-week plan.

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: Pro adds the personalized builder and advanced analytics. Free auto-progression is documented, but this guide does not establish how every recommendation responds to schedule, recovery, or equipment changes.

Bottom line: Consider Boostcamp when you want to choose from named programs; manual custom programs are also free, while personalized generation is a paid feature.

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 descriptions are documentation summaries, not results of our own connectivity tests. Confirm whether a workout must be loaded in advance, whether it can be saved without a signal, and how it syncs afterward before relying on an app at a no-signal gym.

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 documents unlimited free workouts with three custom routines. Compare that known cap with your needs and Hevy's current offer; this guide does not establish a universal Hevy limit.

How we picked

Compare documented ongoing free logging, routine and history limits, program access, and paid upgrades. This is a feature-based editorial shortlist, not a completed subscription or long-term usage test. Trials are separate from ongoing free tiers.

For strength training, compare the documented program tools, progression options, equipment choices, wearable support, and plan limits first. Calorie tracking or a large exercise library will not replace a missing program feature you need each week.

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.

The order reflects our judgment of documented features for this training need, not measured performance or a numerical rating. Handler is our own private-beta product and is excluded from the public shortlist and comparison table.

Separate disclosure: Handler's private beta

Handler is our own product. Handler is in an invited iOS TestFlight beta and does not have a public App Store listing yet.

The private iPhone test build includes program setup, workout logging, coach chat, history and progress review. Apple Watch is in development and offline logging is under test. These are not verified public capabilities or evidence of better results.

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.

Before you commit to an app

During a free tier or trial, enter a familiar workout, log a few sets, and find them in your history. Check whether the program tools you need are included in that tier and whether you can change a suggested exercise or weight.

For watch or offline use, try the exact phone-and-watch setup you train with before taking it to the gym. A documented feature is a reason to shortlist an app, not proof that it will work reliably in your setup. Keep your existing log until you know how to export or recover your history.

Frequently asked questions

What is the best free workout app?
Consider StrengthLog for unlimited logging and basic statistics, Boostcamp for a program library, or Hevy for logging and social sharing. Hevy's documented free limits include four routines and seven custom exercises; this guide does not establish a universal free-tier winner.
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?
This shortlist does not establish an ongoing free AI session generator. Hevy Trainer and Boostcamp's personalized builder are paid features, while Fitbod offers a trial. Boostcamp does document free performance-based auto-progression, which is narrower than generating a new personalized program.
What is the difference between free and free trial?
A free tier keeps core features available without paying. A trial is temporary and may require subscription enrollment upfront: Fitbod's trial renews into a paid subscription unless canceled under its stated terms. Check the cancellation deadline before starting. This guide prioritizes ongoing free tiers over trial-only access.
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.
