One round, one thing. Roundi holds you to a single task and shows the time as color: focus you can see. Turn the dial, press start, and a disc of color begins to disappear — like a kitchen timer for your attention. No numbers counting down, no notifications pulling you back. Just time, visibly running out. THE ONE RULE Leave the app — or lock the screen — before the round ends, and the round is lost, instantly. That's the whole trick: Roundi doesn't block anything, it just makes leaving cost something. (Too strict? There's a Lenient mode.) MADE FOR YOUR RITUALS • Meditate — 15 quiet minutes, watching the color fade • Study — a 50-minute block with no pings • Work — deep work sessions up to 2 hours • Train — planks, dead hangs, rest between sets Save each ritual as a tag and it becomes a one-tap start button with its own duration. SAY IT, DON'T TAP IT "Start Plank in Roundi." Between rounds, Siri sets the length, starts a tag, adds another round, or tells you your streak. Hands free — and once a round starts, nothing interrupts you. ON YOUR WRIST Roundi runs on Apple Watch too. Turn the Digital Crown, tap START, and the color sweeps away on your wrist; a tap and a chime mark the end. Watch rounds land in your iPhone's calendar, Siri works on the watch, and one rule carries over: unlock your iPhone during a watch round and the round ends. A TIMER YOU'LL WANT TO LOOK AT Choose how time drains: a clockwise disc, a color that falls or rises across the whole screen, or a spiral coil that unwinds from the outside in. Six soft colors. A chime and a soft blink of color when the round completes. EVERY ROUND, KEPT Finished rounds land as dots on your calendar, with your daily total and streak. Time becomes habit; habit becomes you. PRIVATE BY DESIGN No account. No sign-up. Your rounds stay on your device. Set a time. Stay focused. One round at a time.
