ReactionTrainer vs TrackTimer

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.
