Comments on Reaction Time for Android

★★★★★ Maks Tuff · Nov 18, 2022

Does what it is supposed to, no fluff, no ads = 5 stars.

★★★★★ Cydoc Voltux · Feb 27, 2023

This is perfect! It is a fast simple way to test your reaction time and gives you an average of five trials.

★★★★★ Cipher37 · Sep 18, 2024

Even an insane developer would add setting to press instead of release. You press to shoot, you click to shoot. You do not release to shoot. Novel = requires retraining.
