About

One Tap Timer

Features
Read full description

A timer that is already running when you open it. Your preset (1:30 by default) starts the moment the app opens. Put it on your watch face as a complication and it is truly one tap. At the end it taps your wrist once, and that is it. No endless buzzing, nothing to dismiss. • Starts instantly. No setup screen in the way • The whole screen drains like water, so you can read the remaining time without reading numbers • Remaining time shown large in plain seconds, with a small 1:33 below • It stays put while running instead of dropping back to the watch face, so the haptic lands exactly at zero • Press the Digital Crown to stop. Nothing keeps running in the background • A stray touch while running does nothing. Tap the finished screen to run it again • Pause from the top-left button. The water turns gray so you can tell at a glance • 10 seconds to 60 minutes, set with −10s / +10s, −60s / +60s, or the Digital Crown • Design the watch-face complication: 5 symbols, 4 rings, how the number shows, size, typeface, 10 colors • The complication shows your preset in seconds (e.g. 90) • Works on Apple Watch alone. The iPhone app is where you pick the look, and it goes to the watch right away • No network, no account, no ads Made for people who time the same thing again and again: rests, steeping, waiting, drills.
