Your first few days

Here’s roughly how it goes

Swipe on small screens →

1First time you open it

Stand the phone up and jump

Put it 1.5–2.5 m away and step into frame. AI watches your form and counts. No counter, no wristband.

2After a few sessions

Not sure what to train? Follow along.

Six training rhythms, each with its own beat track. Follow the drums — no stopwatch, no counting rounds.

3Once it sticks

Badges start lighting up

Streaks, personal bests and new modes all unlock badges. 54 in total, like collecting stamps.

And there’s more

One phone covers all of it

On-device AI pose detection

Jump once, count once

Stand it 1.5–2.5 m away and step into frame. Ordinary lighting and any clothing work fine. The camera feed is used only to recognise motion, then discarded — never uploaded.
