Stop guessing
your rest.
From warm-up to archive, Oxymph stays on your wrist the whole way. How long to rest, how the set actually went, whether today is a push or a hold — it works all of it out and taps you when it is time. You just lift.
From planning your split to
reviewing the session — one app.
Oxymph covers the whole training cycle, with the core free forever. Not a feature dump — only what people who lift actually need.
Rest that learns you
Not a one-size-fits-all countdown. Bodyweight, lifting intensity and recovery capacity differ for everyone — Oxymph starts from a scientific baseline, reads your recovery history and how each set actually went, and keeps calibrating a recovery model that belongs to you alone. The more you train, the better the rest it suggests.
Build your own, or import one
Drag training days into place, pin them to suggested weekdays, and combine freely from a library of hundreds of exercises. Do not feel like planning? The template market is full of plans from creators you follow — import one, it syncs to your watch, and you train today.
Every bit of progress, visible
Volume trends, per-exercise weight curves, PR alerts, per-set quality records — no more training by feel. Open your history and every step of your bench from 60kg to 100kg is backed by numbers.
How the set actually went — the waveform answers
Six-axis wrist motion archived set by set: stability, velocity loss, fatigue. Replay what every set really looked like. Others log what you lifted; Oxymph answers how well you lifted it — the gap competitors leave empty.
Push or hold back? Ask your body first
HRV, sleep, resting heart rate and recent load distill into one readiness score you can read in a minute. On low days it widens today's rests and lowers the fatigue threshold — no need to weigh it yourself.
Built for the wrist
The watch is where Oxymph is at its best. Turn the crown to change weight and reps, feel a light tap for the countdown and a firm one to go. The engine runs locally, so it works offline — raise your wrist and start, never touch your phone between sets.
No phone between setsWorks without a watch
No watch? Your iPhone runs a full session on its own. With a watch, you also get live mirroring and a Dynamic Island countdown. Exercise, heart rate and rest all read clearly on the bigger screen — every frame is polished.
Usable without a watchArchives itself
Finish and it is filed — volume, sets, per-set rest and quality records all kept automatically, and written to Apple Health too. No manual logging. Train and leave.
Automatic loggingBuddy circles
Invite friends into your plan — who is training right now, who just finished, all visible live in the circle. Weekly rankings and a bit of encouragement make training together work even when you are apart.
Never train aloneHow many of these are you?
Resting by feel, never knowing how the set went, no real plan, grinding alone —
the four most common stories in any gym, and exactly what Oxymph is here to end.
These three kinds of lifter share one kind of calm
On heavy days, every set counts
On heavy days, every set counts. Rest too little and you fail the rep; rest too long and you go cold. Oxymph tailors rest to the exercise and your lifting intensity, and learns how each of your lifts recovers — wait when you should wait, go when you should go.
- Crown to change weight and reps — no phone between sets
- Flags muscle-group conflicts before your shoulders pay for it
- Volume, heart rate and quality records, one glance after the set
Nothing to learn. Just follow it.
New to the gym, the worst thing is resting wrong — too short and you cannot push the next set, too long and you cool down. Importa plan a coach actually wrote from the template market in one tap; rest is worked out for your lifting intensity automatically, and your watch taps you when it is time — like a coach keeping time beside you.
- Hundreds of exercises with muscle labels you can read at a glance
- Three onboarding screens and you know the core loop
- Week anchors: train or rest today, obvious at a glance
Train together, from anywhere
Invite friends into a circle and follow the same plan — distance does not matter. Who is lifting and who just finished is live in the circle; the weekly ranking is right there, so your consistency is visible to everyone.
- Invite-code circles, small and tight — join several
- Weekly ranking plus check-in feed, so consistency is seen
- Live training status — train together remotely
Why every Oxymph decision
beats guesswork
Rest too little and the next set suffers. Rest too long and the session drags.
Four layers pin down the rest; wrist waveforms answer how the set actually went.
Tailored with every session
Every workout is a lesson: the model reads how your next set actually went, works out whether the last rest was enough, and keeps calibrating a recovery model that is yours alone. The longer you train, the better it knows how long you need.
A head start on day one
Recovery experience from lifters across the platform becomes a collective prior, so your rest recommendation never starts from zero — it feels like you have trained for a while already.
Everyone starts somewhere different
Height, weight and how heavy you lift change how long you need. Oxymph takes the preset rest for hundreds of exercises and multiplies it by your personal coefficient to get a scientific starting point that is yours.
Calibrating as you train
Waveform decay and actual reps are live readings — a wobblier, slower set means the last rest was short, and the next one adjusts on the spot.
Behind one simple "rest a bit", this is what Oxymph is actually weighing
Not another timer,
not another logbook
Other apps just count down, and after the session there is only tonnage — nobody answers how the set actually went.
Oxymph sits in the gap nobody has taken: scientific rest, movement quality, readiness looped in.

Reliability is designed in
The engine runs on your watch — works offline
The training logic runs entirely on the watch. Bad signal at the gym, phone left in the locker — from warm-up to cool-down, the loop never breaks.
Cloud is the source of truth — nothing is lost
The cloud is authoritative; your device only caches for speed. New phone, reinstall, even a different account — not one workout record goes missing.
Collective insight, gathered anonymously
The collective layer only uses aggregated, anonymous trends — no personal information, and no way to work back to you. Your training data stays yours, always.
Workouts written to Apple Health
Volume, per-set rest and calories are written to Apple Health automatically, so they sit alongside the rest of your activity history.
Training well is always free.
