So simple and so easy to use. Helps develop skills that can translate easily into sum racing.

This is a great app with cool functionality! I have been looking for a replacement since the old Lights Out game changed the app completely and lost the main functionality. All 3 mini games are fun, and the leaderboards keep you competitive. My one big criticism is with the main game mode however. When put in slow motion, the lights fade out slowly rather than a quick off motion. This means that the timer starts at the beginning of the fade when the light is still “on” (just lower brightness). When the brain registers the lights being off, it’s .1 seconds behind on average to when the lights actually begin to be turned off and the timer starts. If the way the lights are turned off were changed to how it’s actually is in F1 (a switch, not a fade), it would make this app 100% better. A smaller recommendation would be to reverse the time stop method. Rather than clicking the screen, I always liked leaving your finger on the screen and taking it off better. Gives faster reactions and replicates the actual F1 race start with the clutch/gears more. Other than that, this is a great starting point for a game genre that was sorely missed by me! I hope it’ll get better down the line, it seems to be made by passionate fans of F1 who also want a game like this.
