Alien Fitness

A minimal, fully offline workout tracker. No account, no server, no tracking — the APK has no internet permission at all. Your data leaves the device only when you export or share a backup yourself, or via Android's system backup if you have it enabled. 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), HIT (Tabata, Power), warm-up and stretching - Warm-up and stretching: a hands-free warm-up block above every workout and a stretching offer when you finish (neither is saved), or run them as their own plans; Thorsten announces the next exercise (by name in German) and when to switch sides, and the timer shows a picture of the next exercise - Live session logging with automatic rest timer, corrections supported - "Last time" on the exercise cards and in every set dialog, sets come pre-filled: progressive overload at a glance - HIT intervals: pick the work time (20–180 s or custom), then a 5 s get-ready countdown, work timer, rest and auto-chained next round - Hold exercises (plank, stretches): pick the hold time per set (30–180 s, custom, or "Max" as a stopwatch), 5 s get-ready countdown; stretches done per side switch sides automatically - Announcer voice: Thorsten calls out "Get ready", "Go", "Rest" and the last round, short tones count down the last three seconds before each automatic start; bundled audio files, can be turned off - Technique tips for every exercise and safety warnings for some, from Kerstin (German and English) - 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, filterable by muscle group, HIT, warm-up or stretching - JSON backup: export saves a file to "Documents" and opens the share sheet (Android 11+; older versions: share sheet only); import with merge (duplicate detection) or replace - German and English interface, switchable in-app - Dark neon UI, screen stays awake during a workout, timer ends with vibration and an announcement (or a beep with the voice off) Works completely offline. Built-in plans use bodyweight, a pull-up bar, dumbbells and a bench — no gym required.
