Minimal, fully offline workout tracker without internet permission — custom plans, HIT intervals, live logging and progress charts.

A minimal, fully offline workout tracker. No account, no server, no tracking — the APK has no internet permission at all, so your data cannot leave your device. Features: - Create your own training plans: any exercise, sets, reps and rest — edit any time - Ad-hoc free workouts: start empty, add exercises on the fly, save when done - Built-in plans: strength (Push / Pull / Legs) and HIT (Tabata, Power) - Live session logging with automatic rest timer, corrections supported - "Last time" shown and pre-filled for every set — progressive overload at a glance - HIT intervals: timed sets run with a work timer, rest and auto-chained next set - Interrupted workouts survive an app kill — resume, save or discard - Session details with every set, a free-text note and delete - Progress charts per exercise (max weight / reps or seconds over time) - Exercise library with images, muscle groups and equipment - JSON backup: export and import (merge with duplicate detection, or replace) - German and English interface, switchable in-app - Dark neon UI, screen stays awake during a workout, timer ends with beep and vibration Works completely offline. Built-in plans use bodyweight, pull-up bar and dumbbells — no gym required.

  • Sep 26, 2026 2.8.0
    Android release v2.8.0 — install via Zap Store or sideload. - Confirmation prompts are now the app's own dialog instead of the Android system dialog. The system dialog does not inherit the screenshot protection of the app and looked out of place; every question now has a matching button ("Delete plan", "Discard", "Cancel workout" / "Keep training", "Replace all"), notices show a single "OK". - Late answers are checked against the current state: a workout that finished while the cancel question was open stays saved. - Selection fields ignore unknown values and do not re-fire on the same value. - No new permissions, still no internet permission. Data format unchanged, backups from earlier versions import as before.
