Programs that progress themselves
Percentage waves, double progression, stage ladders and weekly 5x5. The engine works out the next session from what you actually lifted, including missed reps and skipped days.
A workout tracker with a progression engine that actually reads your logbook. It runs offline, keeps your training on your own phone, and never asks you to make an account.

Percentage waves, double progression, stage ladders and weekly 5x5. The engine works out the next session from what you actually lifted, including missed reps and skipped days.
Strength, muscular endurance and work capacity tracked as trends over months, each built from your own logged sets rather than a formula applied to a single one-rep max.
Import from Strong or Hevy as CSV. Unrecognised exercise names are matched once and remembered, and a bad import can be undone whole.
Every workout is stored locally in SQLite. No account to create. Crash reporting and a closed list of usage events, both of which you can switch off. Export the lot to CSV whenever you want it elsewhere.
Movesesh has no account system and no advertising. Your workouts live in a database on your device. The app makes five network requests: one to this site to check whether a newer version exists, one from Expo's updater looking for a JavaScript bundle, an anonymous session record when the app launches and a crash report if it fails, both sent only while crash reporting is switched on, and a batch of anonymous usage events from a closed list of seven, sent only while usage statistics are switched on. Both switches live in Settings. None of them carries anything that identifies you.Read the full policy, which is written one section per data flow so you can see precisely what leaves your phone.
