Your gym buddy in your pocket
Free · In‑App Purchases
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.
Subscriptions are billed monthly to your Apple ID account and renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple ID → Subscriptions.

• A new exercise library. More than 1,200 exercises, each with an animation showing how it's done, named the way lifters actually say them. Filter by muscle or equipment, and see what else each lift works.
• A better weekly recap. Coach now tells you what stood out last week, what it means, and what to do this week, with the exact weights to aim for. It also tells you when a week was just quiet.
• Fresh plans every 5 days, not 7.
• Redesigned new Home screen.
• Heart rate from your Apple Watch. See your peak heart rate for every set, plus a heart rate chart for the whole session.
• Smoother reordering. Drag exercises into a new order mid-workout without a flicker.
• A friendlier start. New accounts get a short setup that asks how you like to train, then builds your first plan.
• Discarded workouts stay out of Apple Health.
• A new app icon, a native iOS 26 look, and lots of smaller fixes.
