By We make FitNotes X, one of the apps reviewed here. We have tried to write this comparison the way we would want one written about us — concrete criteria, honest weaknesses, no pretending a paid feature is free. Where we are uncertain about another app's current pricing or feature set (these change frequently), we say so and recommend you verify on the developer's own page before downloading.
How to choose a workout tracker (the criteria that matter)
Most "best app" lists rank by features. That is the wrong order, because the features that matter are the ones you will actually use every session for a year. The order we suggest:
- Speed of logging. Can you record a set in 5 seconds or less? If not, you will stop logging within a month.
- "What did I do last time?" Does last session's working sets appear automatically when you start an exercise? Without this, progressive overload becomes guesswork — see our progressive overload guide for why this matters.
- Exercise database depth. Does it cover what you actually train, including less common equipment? 200 exercises is a different product from 800.
- Free tier honesty. Many "free" apps cap workouts per week, lock history after 30 days, or hide PR detection behind a paywall. Check before installing.
- Sync and backup. Does your data live only on one device, or is it backed up and recoverable if you change phones?
- Analytics that matter (not gimmicks). Estimated 1RM trend per lift, weekly volume per muscle, PR detection — useful. Calorie estimates from lifting — not.
- Templates. Does the app let you build a workout plan once and reuse it, or do you start from scratch every session? (Critical for any structured routine like a beginner 3-day full body or 5/3/1.)
The rest — social features, themes, AI coaches, integrations — are nice-to-have, not deal-breakers.
The apps worth knowing about
Alphabetical order. Pricing, free-tier limits, and feature sets change frequently — verify on each developer's page before installing.
Boostcamp iOS · Android
What it does well: Pre-built training programs from well-known coaches. Strong if you want to run a published program (5/3/1, GZCLP, Sheiko) rather than build your own.
Where it is weaker: Less optimized for ad-hoc workouts where you want to put together a session on the fly. Free tier limited; verify current pricing.
Best for: Lifters who want to follow a structured program by a known coach and not think about programming.
Caliber iOS · Android
What it does well: Workout tracking combined with video-coaching content; programs you can follow.
Where it is weaker: More of a hybrid coaching app than a minimalist tracker. Free tier has historically been limited; check current state.
Best for: Lifters who want a guided experience rather than a blank log.
FitNotes (classic) Android only
What it does well: Cult favorite among minimalists. Free. Clean, fast, no nonsense. Long-running and stable.
Where it is weaker: Android only. Limited exercise library (you can add your own). Few analytics beyond a simple chart per exercise. Local-only by default; backup is manual.
Best for: Android users who want a free, fast, no-frills logger and are happy to add their own exercises.
FitNotes X iOS · Android
What it does well: Cross-platform with the speed and simplicity of the classic FitNotes plus a larger exercise library (800+ with male and female video demonstrations), an RPE field per set, automatic PR detection, built-in 1RM calculator (Epley/Brzycki/Lander), built-in rest, EMOM, AMRAP and Tabata timers, and optional encrypted cloud sync across devices. Free to use with no per-week or per-workout cap; an optional Pro subscription unlocks advanced analytics and unlimited cloud history.
Where it is weaker: Newer than the established names, so the community library of user-shared programs is smaller. No third-party platform integrations yet (Apple Health / Google Fit are on the roadmap).
Best for: Lifters on either platform who want a fast logger with serious analytics, exercise videos, and timers in one app.
Hevy iOS · Android
What it does well: Modern UI, broad exercise library, active development, social-feed component for users who want it.
Where it is weaker: Some analytics features sit behind a Pro tier; check current state. The social feed is a feature for some users and a distraction for others.
Best for: Lifters who want a polished modern app with optional social features.
Jefit iOS · Android · Web
What it does well: One of the longest-running tracker apps. Large exercise library with illustrations. Built-in programs and community plans. Free tier exists.
Where it is weaker: UI has accumulated complexity over the years; the free tier shows ads. Some users find the interface slow at the gym compared to newer apps.
Best for: Lifters who want a long-established product with a deep program library and do not mind a denser UI.
Strong iOS · Android
What it does well: Polished UI, fast at the gym, the original premium iOS tracker that set the standard.
Where it is weaker: Historically the free tier caps the number of workouts you can save per week — making it a paid-only product for most serious users. Verify the current free tier on the developer page.
Best for: iOS-first lifters willing to pay for a clean, premium tracker.

How to pick in 60 seconds
What to look for in the first session
Whichever app you pick, the first session is a quality test. Ask:
- Did you log a set in under 5 seconds?
- When you started the second working set, did the previous set's numbers appear automatically?
- Could you find the next exercise quickly without scrolling 800 entries?
- Did the rest timer auto-start when you finished the set?
If three or four answers are "no," try a different app. You will not change a slow logging workflow in week 4 — you will just stop logging.
What to migrate (if you switch apps)
If you have history in an existing app, check whether the new app supports import. FitNotes X imports from FitNotes (classic), Strong, Hevy, Jefit, and Gymrun via CSV/JSON; other apps vary. Losing two years of history because the importer does not support your old app is the most common switching regret — verify before committing.
Truly free, both platforms, no workout caps
800+ exercises with male and female video, RPE field, automatic PR detection, EMOM / AMRAP / Tabata / Rest timers, and encrypted cloud sync — all in the free tier. Pro adds advanced analytics and unlimited cloud history.
What none of these apps will do for you
- Fix bad programming. A great log on a bad program is still a bad program. Spend 10 minutes choosing a sensible plan — linear progression for beginners, 5/3/1 or Upper/Lower for intermediates, PPL for advanced hypertrophy focus. See our sets-per-week guide for volume targets.
- Replace consistency. The best app you do not open is worse than the worst app you open every session.
- Make you stronger by themselves. Tracking is the feedback loop; the work still has to happen.
FAQ
Is there a truly free app with no workout cap?
FitNotes (Android only), FitNotes X (iOS and Android), and Jefit (with ads) are the three most established options that do not cap workouts. Hevy has a generous free tier as of last check, but verify the current state on the developer's page.
Do I need cloud sync?
If you only use one device, no. If you change phones, switch between iPhone and iPad, or are paranoid about losing history, yes. Cloud sync is a feature you do not value until you need it.
Should I trust a free app with my training data?
Reasonable caution. Check the app's privacy policy and whether it exports your data in a portable format (CSV or JSON). If you cannot get your data out, you do not really own it.
What about Apple Fitness or Google Fit?
They are activity trackers, not strength loggers. They count calories and steps; they will not give you weekly volume per muscle or PR detection. For lifting, use a dedicated app.
Does the app matter, or is paper just as good?
Paper works perfectly for the first 6 months. Once you have a year of history and want to ask "is my bench press 1RM going up?" without flipping through 60 pages, an app starts to pay off.
Bottom line
The "best" workout tracker is the one you will open every session for a year. Test two or three free options for two weeks each. Pick the one that lets you log a set without thinking and shows you last session's numbers without scrolling. The rest is decoration.
