Bodybuilding
Hypertrophy, volume, the whole gym. The full experience: catalog, generator, exercise-by-exercise progression.
Training A log that keeps up,
A log that keeps up,
not a spreadsheet to fill in.
One card per exercise, your sets in a row, weight and reps right where you read them at arm's length. You tap done, and the app handles the rest timer, the volume, the records, and what you load next time.
Keep your head in the iron.
The app handles the rest.
Rest starts on its own, your next load is already calculated, one thumb tap logs the set.
New
Three disciplines, one app
A switch at the top of the Training screen reconfigures the whole hub: competition lifts, ready-made sessions, rest times calibrated for strength. Your choice is remembered.
Powerlifting
Squat, bench press, deadlift. Ready-made sessions in 5×5 and 5×3, four to five minutes of rest on the big lifts — strength needs recovery.
Streetlifting
Weighted pull-ups, dips and muscle-ups, squat. Added weight logs set by set, belt included.
The log
Everything fits on one card per exercise
The set table sits right inside the card. Add a set, remove one, add an exercise mid-session: nothing forces you to plan your session ahead or finish it the way you started it.
Warm-up
Counted in the session, excluded from volume and stats. Working up in weight never inflates your curves.
Working set
The set that counts. It feeds the volume, the records, and the suggestions.
Drop set
You strip weight and go again with no rest. Linked to the set it extends.
Failure
The set went all the way. The engine factors that in to decide whether you're stalling or not.
Warm-ups never count toward volume or stats. It's the only way to have curves that actually mean something when you work up through five sets before the first real one.
During your session
Your phone stays in your pocket
Rest timer
It starts on its own the moment you log a set and keeps running in the background. On iPhone, the countdown shows in the Dynamic Island: it keeps going even with the app closed, so you put the phone away and just hear when rest is up.
Supersets
Groups two or more exercises together. The log keeps the link between them and carries you from one to the next without scrolling back up the list.
Session recovery
If the phone kills the app mid-session, you find it exactly as you left it on restart: logged sets, timer, current exercise.
Apple Watch
Your current session follows on your wrist. You check where you stand without pulling the phone out of your pocket.
New · Apple Watch
Your session lives on your wrist
Start, log your sets, finish or abandon — without pulling out your iPhone. Your watch's heart rate shows live in the app while you train.
- Live banner: timer, heart rate, calories
- Weight and reps side by side, adjusted with the Digital Crown
- Session stays visible even out of range of your phone
- Your sessions written to Apple Health, no duplicates
Progression engine
It tells you what to load, and why
Every suggestion comes with its reason, written right under the exercise. No black box: you can always overrule it and load whatever you want.
+2.5 kg this session Your last 2 sets went with 3 reps in reserve.
Double progression
DefaultYou climb reps to the top of your range. Once every set hits the top, the weight goes up and you start back at the bottom of the range.
Linear
A fixed increment every successful session. Simple, readable, effective for as long as it works.
Greyskull LP
The last set goes for max reps. One big set speeds up progression, and a miss triggers a deload instead of a reset.
Bodyweight
Nothing to add to a bar: progression is played out in reps and in the difficulty of the variation.
Self-regulation with RIR
RIR stands for reps in reserve: how many more you could have done. A successful set with 3 reps in reserve pushes the load up faster than a set ground out to the limit. Conversely, a miss with reps still in reserve isn't read as a stall — you stopped, you didn't cap out.
Personal records
Detected, never entered
No record is ever typed in by hand. The app spots them in your logged sets the moment you set them. The only way to see one show up is to have actually done it.
Import
Your history comes with you
One single entry point for all three formats. Drop your file, and the app figures out on its own where it came from — no list to pick from.
Hevy
CSV export from the app.
Strong
CSV export from the app.
FitNotes
CSV export from the app.
Rows the import couldn't read don't just vanish: they're listed for you at the end, each with its reason. You see exactly what went through and what got left out.
Posture analysis
The camera watches your form
Set the phone down and do your set. Detection runs live on 17 key points of your body and tracks your movement as you do it. Nothing to upload, nothing to send off: it's the camera and the analysis, right there.
