Swimmers leave the wall on staggered intervals, so one clock can't give them all an honest time. Brainzie Poolside times each one individually — across the whole lane, every rep — straight from your phone.
Big tap targets for wet thumbs, high-contrast in bright light, and the screen stays awake while you time. Every time is captured at the tap — the display never affects accuracy.
Send a whole lane off on 5–10s intervals and tap Stop for each swimmer as they finish. Every swimmer gets their own accurate time, ranked within the heat and overall — up to eight lanes.
Follow one swimmer through a whole training session — splits per length, rest between reps and sets, swim-to-rest ratios, and a tidy summary you can share. Pick up where you left off if you close the tab.
Split a single race length by length, with underwater times and surface speed, a dive-aware projected finish, and pacing against a target. Miss a touch? It's folded back in so your total and average stay exact.
A swim-optimised strength guide: each lift paired with the matching stroke phase, animated from several angles, showing which muscle fires and when — for freestyle and breaststroke.
Nothing to install, no account to create. Add it to your home screen and it opens like an app.
Group set for a lane, My session for one swimmer, Race for a single swim — whatever the session needs.
Times are captured the instant you tap. Share a clean summary as an image or text when you're done.
Poolside runs entirely in your browser. Your swim times never leave your phone — there's no account and nothing uploaded. The only thing we collect is anonymous usage counts (which tools get used, how often) so we know what to improve — never any times or personal data.
