Best Offline Workout Tracker for Android (2026)

Basement gyms, converted garages, and older commercial gyms share one trait: unreliable signal. If your tracker needs a connection to log a set, you find out exactly when it's most annoying — mid-workout, phone stuck on a loading spinner while you're trying to log 225x5 before you forget the number.

These five don't have that problem, because logging never touches a server in the first place.

1. Stay Fit

Every part of the core workflow — guided sessions, logging, rest timers, custom routines, progress reports — runs entirely on-device. There's no login step to fail and no sync spinner to wait on. Backup happens on your terms: export a JSON or CSV file whenever you want one, and share it to Drive, Files, or wherever you keep backups. No account exists to be "offline" from in the first place.

2. FitNotes

FitNotes has run fully offline since well before "offline-first" was a marketing term — it predates the current wave of privacy-focused fitness apps by years. Ad-supported, so you'll see banners, but the actual logging and history functions never depend on connectivity.

3. Plates

Plates keeps its scope narrow specifically so offline logging stays simple: sets, reps, weight, and progressive overload tracking, no calorie sync or leaderboard features that would need a server round-trip. Training data stays local because there's no cloud component to sync to at all.

4. Iron Log

Iron Log's ghost-set feature — showing your previous session's numbers while you log the current one — reads entirely from local storage, so it works exactly the same with airplane mode on. Export options (TXT, CSV, JSON) are all local file operations too.

5. GymMane

GymMane doesn't request Android's INTERNET permission, which is a stronger claim than "works offline" — it's structurally incapable of a network call. If offline is a hard requirement rather than a nice-to-have, this is the one with a code-level guarantee instead of a policy promise.

What "offline" doesn't mean

None of this means these apps can't be backed up or moved between phones — it means logging itself never depends on a connection. Stay Fit, for instance, still supports full backup and restore; the difference is that backup is an export-to-file action you trigger, not a background sync that has to succeed for the app to work.

Strong and Hevy are worth a note here too: neither requires connectivity to log a workout in the moment. Where they need a connection is account sync, cloud backup, and (for Hevy) the social feed. If your gym has spotty signal but you eventually want to sync from home Wi-Fi, that's a workable middle ground — just don't expect the app to feel fully functional the first time you open it with zero signal and no prior local cache.

Picking between the offline-first five

Stay Fit if you want the most complete feature set — goals, measurements, streaks, analytics — alongside offline logging. Plates if you want the smallest possible app doing the fewest things well. Iron Log if progressive overload tracking is the priority. GymMane if you need a verifiable, permission-level guarantee that nothing can leave the device. FitNotes if you don't mind ads and want the longest-running option in the category.
