Android

A minimal, fully offline workout tracker. No account, no server, no tracking
— all your data stays on your device and never leaves it.

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
  • Progress charts per exercise (max weight / reps over time)
  • Exercise library with images, muscle groups and equipment
  • JSON backup: export and import your history and plans to move between devices
  • German and English interface, switchable in-app
  • Dark neon UI, fully mobile-first

Works completely offline. Built-in plans use bodyweight, pull-up bar and dumbbells —
no gym required.
