CubeTimer

Offline 3×3 speedcubing timer with TNoodle scrambles
New in version 1.0.4
Enable R8 code optimization and resource shrinking for release builds.
CubeTimer is a focused offline timer for 3×3 speedcubing.

It generates random-state scrambles with a local port of TNoodle-lib, the WCA scramble program. The cube map updates to match every scramble, so you can inspect the state before starting.

Features:

- Tap-to-start and tap-to-stop timer.
- Random-state 3×3 scrambles generated offline.
- Cube map synchronized with the displayed scramble.
- Local history of up to 200 solves.
- Best, worst, mean, ao5, ao12, best ao5, and best ao12 statistics.
- Delete a solve with undo, or clear the history with confirmation.
- Solve detail card and PNG sharing.
- Light and dark themes.

CubeTimer has no account, ads, analytics, or Internet permission. Solves remain on the device. A shareable PNG is created only when you request sharing through Android's share sheet.
