Stroke started as a way to stop losing sets to a wet notebook. Scan the whiteboard, say the set out loud, or type it once and reuse it — then watch every best time, split and points score add up over a season.
How you log
Most trackers assume you're wearing a $200 watch or want to type out every 100 by hand. Stroke assumes you're standing on deck with wet hands and thirty seconds before the next rep.
Photo scan
Point your phone at the whiteboard. We read your coach's handwriting — shorthand, arrows and all — and turn it into a logged set.
SoloVoice record
Say it the way your coach says it — "ten by one hundred free on one thirty" — and it lands as a structured session automatically.
SoloManual entry
Type it once, save it as a template. Most swimmers never type the same set twice — next time it's one tap.
FreeThe whole point
Not five minutes hunting for the app you meant to open. Five seconds, wet fingers and all.
Set library
A built-in library of complete workouts — warm up to cool down, with coaching notes — written the way coaches write them. Pick what today needs, log it in one tap, or print a deck sheet for the pool.
