About

Lido

Read full description

Lido is a workout timer with a pool. Build your workout, press play, and put the phone down. Lido speaks — it announces each exercise, calls halfway so you know when to switch sides, and counts down the last five seconds, even with the screen locked. Finish a workout and a toy floats in your pool: a rubber duck, a beach ball, an orca, a flamingo. One toy per workout, a fresh pool every month. It's a workout log you'll actually want to look at — and every so often, a gilded toy turns up. THE TIMER • Timed circuits with spoken cues — hands-free from first exercise to last • Untimed checklists for gym days: sets, reps, and a rest clock • Halfway and five-second alerts, per exercise • Keeps talking with the screen locked or the app in the background SETS • A standalone rest clock for the bench — tap when you rack the bar, lift when it says go • Start it from Control Center or the Lock Screen without opening the app THE POOL • One toy per finished workout, in your workout's color • Monthly pools you can swim back through • Rare gilded toys, if you're lucky SHARE • Send a workout to a friend as a link — it opens in their Lido, ready to add • No account needed on either end EVERYWHERE • Home Screen widgets for your week and your pool • Lock Screen accessories • Night Swim — a dark mode that lights the pool after sundown PRIVATE BY DESIGN • No account, no ads, no tracking, no subscription • Everything stays on your phone • Shared workouts travel inside the link itself — no server ever sees them Free. Made by one person and a rubber duck.
