Readiness dial
A dial on home reads your load and your rest, then says whether today is fresh, steady or tired.
A trainer in your pocket. A log in your hand.
Tell Rhino what you want to train and get a full workout back. Exercises, sets, reps and weights. Then tick off each set as you go, adjust on the fly, and watch your streak grow. Your workouts stay on your phone, and the app speaks nine languages.

The important bits
Six things Gym Buddy does that a notes app cannot.
Live Activity
The set you are on and the rest timer stay on the Lock Screen and the Dynamic Island, so the phone can sit face down.
Apple Watch
Live heart rate in your own zones, the set count and the timer on your wrist, and readiness on the watch face.
Nothing lost
Sets are saved as you train, so a phone call an hour long still puts back your ticks and your rest timer.
Ask Rhino
Plans, swaps and form questions, in a tab of its own. Ask mid-workout and it knows where you are.
Friend streaks
Train on consecutive days to keep your own streak, and share a workout to build one with a friend.
Plan it, do it, keep it going
The whole loop is four screens, reached from the floating tab bar at the bottom: Home, Progress, Rhino and Settings. Nothing to set up, nothing to sign in to.
1
New workout · Rhino
Describe the session
“Upper body push, 45 minutes, dumbbells and a bench.” Rhino replies with a table of exercises, sets, reps and starting weights. Talk it over until it looks right, then tap Save.
2
Workout · set by set
Train from the card
Each exercise shows the set you are on, its weight and reps. Swipe a set to the right, or tap the tick, to complete it and move on. Tap the weight or reps to change them, open the overview to see every set at once, or use the chat button in the header to ask Rhino about the session you are in.
3
Progress · streaks
Finish and see the streak grow
Hold the finish button to save the session, so a brush of the thumb can never end a workout. Home shows your streak and your readiness for today, and the Progress tab adds the muscles you trained this week, your trophies and a heatmap of every day you turned up.
What it does
The detail is in the FAQ, and the long form is in the documentation.
Workouts written by Rhino
Tell Rhino the goal, your time and your kit, and get a plan back.
Set-by-set tracking
One card per exercise. Swipe a set to the right to tick it off.
Pick up where you left off
If iOS closes the app mid-session, the next open puts everything back.
Readiness, before you start
A dial reads your training load and says how today looks.
Streaks, freezes and holidays
Train on consecutive days. Freezes and breaks hold the streak, and a hundred dated days are there to win.
Muscles this week
A rhino, front and back, tinted by the sets each muscle got this week.
Last time, PBs and progression
Every card shows last time, and the next weight follows the work you did.
Where you stand
Every lift classed Beginner to Elite for your body weight and your age.
Rest timer and supersets
A countdown starts on each tick and carries on over the Lock Screen.
Heart rate in your own zones
A Watch, AirPods or a strap, in zones built from your own threshold.
Cardio, walks and rides
Runs, rows and carries in their own terms, plus anything Health records.
Trophies worth opening
PBs, medals, milestone ladders and icons, with the empty slots on show.
Rhino ranks up with you
Showing up earns XP. Eight bands, Bronze to Legend, each with its own kit.
Apple Watch and complications
Readiness, heart rate, the set count and the rest timer on your wrist.
Rhino Pro, when you want it
Fourteen days free after your first workout. The basics stay free for good.
Your workouts live on your phone
Back them up to your account if you sign in. No ads, no trackers.
Meet Rhino
Rhino is the trainer inside the app, and it has a tab of its own in the bar at the bottom. Ask it anything about training, form or food, there or mid-workout. When you ask during a session, Rhino already knows which workout you are doing and how far through it you are.
In the editor, Rhino can also revise a saved workout for you: make it easier on your knees, harder, shorter, or heavier on back work. You see the proposed changes before anything is saved.
Rhino is an AI model, not a coach or a clinician. Its suggestions are general fitness information. Read the disclaimer.
I’m on set 3 of squats and my lower back is tightening up. Should I keep going?
Tightness is a cue to check form, not to push through.
• Brace before you descend and keep the bar over mid-foot
• Drop to 70 kg for the last two sets
• Rest 2 to 3 minutes between them
If it turns into sharp pain, stop the exercise for today.
What should I eat after this session?
Aim for roughly 30 g of protein and some carbs within two hours:
| Meal | Protein | Carbs |
|---|---|---|
| Chicken and rice | 35 g | 60 g |
| Greek yoghurt and oats | 25 g | 45 g |
| Tofu stir-fry | 28 g | 50 g |
