Solo Leveling Gym
A gym tracker built as a Solo Leveling status window: every set earns XP and attributes, a daily quest waits each morning, and rank evaluations gate the next tier.
The game is honest about the training underneath. XP comes from effective volume with diminishing returns per set and RPE weighting, so junk sets do not farm levels; attributes grow in proportion to what was trained; the streak rewards consistency, and a missed daily quest sends you to the penalty zone.
Under the theme it is a complete tracker: 876 exercises, routines, supersets, a plate calculator that never rounds up, progression charts with an estimated one-rep max, records, a training calendar and a full backup that restores into a different account.
It runs on a device-local backend or on Firebase behind the same repository interfaces, and falls back to the device by itself when a Firebase project is not ready. 21,000 lines of Dart and 146 tests.
