## What is One Tap Timer?

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
• Ten colors, applied to both the timer screen and the watch-face complication
• The complication shows your preset in seconds (e.g. 90)
• Works on Apple Watch alone or iPhone alone. Installs on the watch without the iPhone app
• No network, no account, no ads

Made for people who time the same thing again and again: rests, steeping, waiting, drills.
