Train your reflexes for faster race starts. Here is how it works :
Push the start button. Then, every 5 seconds
- The app says Ready
- Between 1.5 and 2.5 seconds later (random), your hear a shot
- Tap the screen to simulate a start as fast as you can.
This sequence repeats itself until you push Stop.
Reaction times are stored for later analysis. The free version gives you 5 attempts before issuing a request to buy - just enough to know how it works. Unlocking is available as an in-app purchase. You can force-quit te app to get another 5 attempts, but past attempts will no longer show in the history table and graph. They are kept on file though for when one should choose to buy later.

More features
- Turn sound on or off.
- Turn visual clues on or off (orange dot when Ready, green dot when shot sounds)
- On iPhone 6s or later, you can use 3D touch so you can leave your finger on the screen. When the start is given, just push harder.
- Reaction times of less than .01 seconds are considered false starts.
- No publicity.
- Attach your phone on your arm, listen for on your marks, (step in the blocks), ready - go. Your phones movement detection will measure your reaction time.
