About Clean Timer

I couldn't find a single cube timer app on Google Play that is:

a) not ridden with ads

b) looks nice

So I tried to make one myself! My vision was to implement the features expected of such a timer while staying true to its original purpose, including:

- Allowing for 15 seconds of inspection time as per World Cube Association competition ruling

- Generating random scrambles

- Career statistics: recent/historical averages and ability to manage previous solves

- A light/dark theme

How to install Clean Timer

  1. Tap Download — the app's official page on F-Droid opens.
  2. Install it with the F-Droid app (recommended, for automatic updates), or use the download button on that page.
  3. If Android asks, allow the F-Droid app or your browser to install apps, then tap Install.
  4. Open Clean Timer from your app drawer.
