Gym Buddy: Rhino

A rhino for a coach. A log in your hand.

Gym Buddy is a strength-training log with Rhino, an AI trainer who plans your workouts around your gym's equipment, counts your sets, runs the rest timer on your Lock Screen and Apple Watch, and keeps a streak that allows rest days. Everything stays on your phone unless you choose to sign in and back up.

PLAN WITH RHINO
- Tell Rhino your goal, how long you have and what equipment is around
- Get a complete workout back in seconds, with starting weights
- Keep talking until it is right: swap exercises, make it lighter, make it shorter
- Ask Rhino to revise a saved workout: easier on the knees, harder, more back work
- Strength, cardio, timed holds and stretches, supersets

TRAIN SET BY SET
- One card per exercise showing the current set's weight and reps
- Tick off each set as you finish it; the rest timer starts on its own, with what you lifted last time beside it
- Timed sets get a Start button, a 3-second lead-in and a countdown that buzzes when the hold is done
- Tap a weight or reps chip to adjust it, with quick +/- controls
- Edits are saved back into the workout for next time

ON YOUR LOCK SCREEN AND YOUR WRIST
- The whole workout runs on the Lock Screen and in the Dynamic Island: exercise, set, heart rate and rest countdown, with buttons to complete a set, add 30 seconds or skip the rest without unlocking
- Apple Watch app with live heart rate and zone, the current set, the same controls and Now Playing on your wrist
- Heart-rate zones from warm-up to maximum, from Apple Watch (or AirPods Pro 3 on iOS 26), or any Bluetooth chest strap or armband
- Sessions save to Apple Health with average and peak heart rate
- A Home Screen widget with Rhino's mood and your streak

YOUR GYM
- Find your gym and see the equipment other members have listed
- Add it all in one tap, and Rhino only plans exercises you can actually do
- Publish your own list when you are ready, so the next person benefits

STAY CONSISTENT
- A streak that allows rest days from your weekly plan, and freezes you earn by training
- A trophy room: personal records, streak medals, a badge for every month you hit your target, milestone ladders for each lift, weekly event badges
- Eighteen collectible app icons, unlocked by what you do
- Weekly events, the same challenge for everyone every Monday
- Friend streaks: share a workout and keep a streak together
- An activity heatmap shaded by how much you did, last-time hints on every set, estimated 1RM
- Year in Lifting, made on your phone

ASK ANYTHING
- Chat with Rhino about technique, recovery or nutrition
- Ask mid-workout and Rhino knows exactly where you are in the session

YOUR DATA STAYS YOURS
- No account required, no ads, no tracking
- Workouts and history are stored on your phone
