AI swim coach · iPhone & Apple Watch

Most swim apps count laps.
SwimAI watches you swim.

Film one length from the deck. SwimAI tracks your body frame by frame, measures your stroke, names the one fault costing you speed, and writes your training week around fixing it.

How it works

From one length to a whole week.

1

Film one length

Prop your phone on the deck and swim past it. Any pool, any phone. No wearable, no markers.

2

Get the read

17 body points tracked on every frame. Your level, stroke rate, stroke count, speed, distance per stroke, and the faults that matter.

3

Train the fix

Kai, your coach, builds your sessions around that fix: warm-up, drill, main set, cool-down, with the why and the cue for each.

Live demos

Two real swimmers. Two real analyses.

Not mockups. Each clip went through the same pipeline the app uses today, with the overlay, the numbers, the plan and Kai's answer exactly as they came back.
