About this game

This is a simple tool to measure your reaction time.

Response time is the sum of reaction time and movement time. Usually the focus in research is on reaction time. There are four basic means of measuring it but in this app we use only one:

- Recognition or Go/No-Go reaction time tasks require that the subject press a button when one stimulus type appears and withhold a response when another stimulus type appears.

Warning: Each device is different and there may be additional delays depending on the number of background processes and the age of the device.

It's great on its own, did pretty much exactly what I want, but the ads are completely ridiculous. the small ads at the bottom are fine, but the video ads are really obnoxious, and often times they're ads for some porn website or something. This is just a reaction time test with 1 extra mode and a leaderboard, I'm not paying to remove ads when there are hundreds of other apps that do the same thing free for no ads.

Pretty good, and effective, does it's purpose well. However, the only issues is the ads and their placement, the ones at the bottom affect my reaction time by being in my peripherals, and the pop up ads are very sudden and cause me to click them sometimes. Overall pretty good. Definitely would recommend use of this app to friends and family๐Ÿ‘

don't bother with this app. It puts you in an over 3 minute ad after using it for 20 seconds.
