Film every swim.
See what to fix.
Put your iPhone on a tripod and swim — SwimLab starts the camera for you, times every rep to the hundredth, and replays it frame by frame. For swimmers training on their own and coaches who can't watch every lane at once.

See what you can't feel.
Set the phone on a tripod, get in the water. SwimLab handles the starts, the filming, the timing, and the rest intervals.
A real starter in your phone
Whistles, “take your marks”… and a gun timed to Olympic-final cadence — 1.6–2.4s after the call, occasionally slower. No anticipating it.
Start from the water
Raise your arms — the torch blinks back and the start runs itself. The camera re-arms after every swim, hands-free.
Sets that run themselves
5×50 on 3:00 — voice countdowns, every rep filmed, the next gun exactly on the send-off. A coach with a stopwatch, minus the coach.
Times you can trust
Corrected for the speed of sound and verified against the start tone in your own recording — honest to the hundredth, even over a Bluetooth speaker.
Every session, studied
Search, filter, and star your swims — real video thumbnails, gun-to-wall times, and frame-by-frame review with every moment marked.
Share the proof
Feature your time, reaction, or breakout with the clock burned in — sized for Reels, trimmed to the moment.
Free on iPhone — questions welcome.
