Your AI gym coach. Log every set in seconds, see your progress on clear charts, and get insights from every lift you do. Train smarter, one set at a time.

jimmy is the gym buddy who never forgets a number.

Log every set in seconds — weight, reps, done. Your history, your PRs, and your progress are always one thumb away, so you can spend the rest between sets actually resting.

TRACK EVERY REP • Build workouts from your exercise library or saved routines • One-row set logging: weight × reps, no clutter • Rest timers that start themselves • PR detection that celebrates the moment you beat your best • Add or swap exercises mid-session

PROGRESS, VISUALISED • Strength trend per exercise (estimated 1RM) • Volume, reps, and consistency charts from 7 days to a year • A consistency heatmap that makes streaks addictive • Muscle-group balance at a glance

YOUR LIBRARY, YOUR RULES • Start with 40 curated exercises, add more from a 700+ exercise bank • Step-by-step how-tos with images on every bank exercise • Create your own custom exercises and routines

ON YOUR WRIST • Start on your iPhone and the Watch app opens itself • Log sets from your wrist — swipe between exercises, no phone needed • Live heart rate and calories while you train • A session view with your heart-rate curve and every set on a timeline • Workouts save to Apple Health and close your rings

COACH (OPTIONAL, AI) • A weekly plan built around your goals, schedule, and equipment • Set-by-set target weights computed from your own training history — by maths, not by a language model • A short weekly recap: what went well, what to push next • Off by default. Plans are written by Claude (Anthropic); you're told exactly what's shared before anything is sent

HONEST PRICING 30 days free — no card, no strings. After that, pay what feels fair: plans start at $1.99/month and every plan unlocks the same full app.
