Bestiary

Unleash the beast. One app, all your data: log your workouts, meals, sleep and weight — the AI Coach cross-references them and tells you what actually matters.

Each region of the beast lights up based on the weekly volume you've logged, compared against scientific-literature thresholds (sets per week per muscle group). The thresholds are adjustable: tune them to your body and experience.

Maximum volume — at the ceiling, risk of too much
Optimal volume — in the growth zone
Below minimum volume — too little to stimulate
Not trained / logged — no data this week
Coming · 2026
