1vs1 Cube Timer is a simple Rubik's Cube timer designed to challenge your friends head-to-head. The app allows you to put your finger on the timer and wait for your friend to be ready. Once you release your finger, the timer starts, and the first person to finish wins.

The app provides scrambles for all official WCA events, which are generated using the TNoodle open-source scramble program, the same one used in official competitions. This ensures that the scrambles are accurate and fair.

Overall, 1vs1 Cube Timer is a great app for anyone looking to challenge their friends to a Rubik's Cube competition. The app is free to use, and easy to navigate.
