# 🌀 Coil



This is a visual timer app, like a [pomodoro timer](https://en.wikipedia.org/wiki/Pomodoro_Technique). Open it on your phone, save it to your home screen, et voila! Drag clockwise to wind it up, tap to start or pause it.



[Start using Coil](https://z0u.github.io/coil-timer)



Features:



- **Distraction-free:** Subtle visual changes and silent while running

- **Stays on:** Your screen won't automatically close while the timer is running and focused

- **Screen protection:** The display changes subtly to prevent pixels from remaining lit for too long[^protection]

- **Battery-saving:** Dark mode with a pitch-black background to take advantage of OLED screens

- **Persistent sessions:** Remembers the end time that you set, even if you close the app — simply re-open it to resume

- **Nothing to install:** Coil is a progressive web app (PWA) — just [open the web page](https://z0u.github.io/coil-timer) to use it. You can optionally install it by saving it to your home screen.



Controls:



- **Start/stop:** Tap the clock face

- **Adjust duration:** Swipe to turn the clock face like a dial

- **Fullscreen:** Press the fullscreen button, or double-tap outside the clock face

- **Show/hide controls:** Tap on the edges of the screen







  

    

      

        Mobile screenshot showing a bright red timer on a black background. It looks like a clock face, but with no numbers, and with an arc showing the remaining time instead of hands. Two ticks can be faintly seen at 30 and 60 degrees, where the 1 and 2 numerals would be on a regular clock.

      

      

        Mobile screenshot showing a bright red timer on a black background. Two concentric arcs showing the remaining time: the outer arc is a full red circle, and the inner one spans from the top to about 60 degrees, where the numeral 2 would be on a regular clock. White text in the center reads 1:10. A fullscreen icon button is at the top-right.

      

      

        Mobile screenshot showing a bright red timer on a black background. Eleven concentric arcs show the remaining time: the outer arcs are dim, while those near the center are thicker and brighter. The innermost spans from the top to about 270 degrees, where the numeral 9 would be on a regular clock. White text in the center reads 10:45. A fullscreen icon button is at the top-right.
