iPhone + Apple Watch · Strength training assistant

Rest intervals,
no guessing.

AI rest · Movement quality · Recovery readiness

How long should this rest be? Should you push today? When did the set start to fade? Oxymph connects the evidence before, during and after training. A quiet tap on your wrist tells you when to go.

Before, during and after training

An evidence-based answer at the moment you hesitate

Not more numbers for the sake of it. Just a clear next step at the three moments that can change a workout.

Before · Recovery readiness

Push or hold back? Ask your body first

You slept a little longer than usual, and today’s readiness is 7 points above normal. Open Oxymph and you do not have to decode a wall of metrics: 77 says you are ready to train, then rest adjusts with your physical state.

Know how to train today before you learn every metric.

During · AI rest

Not a fixed 90 seconds — a recommendation that learns session by session

Too little rest and the next set fails. Too much and you go cold. Oxymph weighs the exercise, intensity, muscle relationships and actual performance to time this rest. Every real session then calibrates the next one.

A quiet tap on your wrist when it is time. No watching a timer on your phone.

After · Movement quality

Weight and reps log what you lifted. Waveforms show how you lifted it

The same 26 kg × 12 can look very different in set one and set four. Per-set quality, every waveform, velocity loss and stability show where the set began to fade — and why your next rest changes.

Not just “workout done”, but “this is how that set actually went”.

With or without a watch, train properly

iPhone is your complete training home. Watch puts the critical moment on your wrist.

No watch is not a lesser signup. A watch simply adds signals that only the wrist can provide.
