Underwater Stopwatch & Timer
Read full descriptionHide full description
A lightweight Apple Watch stopwatch and timer built for wet hands, that also works on iPhone alone. Everything is controlled by rotating the Digital Crown, so you never need the touchscreen. It keeps working when your fingers are wet, gloved, or underwater, and while your watch is in Water Lock. TWO MODES Stopwatch counts up from zero, with laps. Timer counts down from any duration you set, drawn as a draining hourglass, with three unmistakable buzzes at zero. Run past zero and the overtime is recorded too. CROWN CONTROLS Rotate up to start, pause, and save. Rotate down to add a lap, or to continue a paused session. No taps, no buttons, nothing to fumble for. HAPTIC TIME CUES Set a repeating buzz at any interval, plus an optional stronger one for milestones. A light tap every 30 seconds and a firmer one every 5 minutes, for example. Track elapsed time without ever looking at your wrist. STAYS ON SCREEN The app holds the display for your whole session, so a glance shows your timer instead of the watch face. ON YOUR IPHONE No watch? The iPhone has its own stopwatch and timer, with laps, an alert at zero, and a Live Activity on your Lock Screen. Start a session on your phone and your watch shows it live. Every watch session syncs across: full history, lap splits with faster and slower comparisons, and your average and longest times. Set durations and cues from either device. BUILT FOR Swimming and pool laps. Surfing. Cold plunges and sauna rounds. Breath-hold and apnea training. Anything you time where looking at a screen is not practical. PRIVATE BY DEFAULT No workouts. No fitness tracking. No Health data. No account, no subscription, no ads, no analytics. Every session stays on your devices. FEEDBACK WELCOME Underwater Stopwatch is made by one person, and every email gets read. Ideas, bugs, or the activity you use it for: hello@softuki.com, or tap Send Feedback in Settings.
