On your marks
After On Your Marks, move into the blocks, place your hands, set your feet and become still. RaceCue waits for the selected On Your Marks-to-Set interval before giving Set. Use fixed timing to repeat the same rhythm, or Premium random timing to stop athletes predicting the command.

Before you take it to the track.
Does RaceCue work offline?
Yes. Starter audio, training tools, and local session history are designed to work without an internet connection. Buying or restoring Premium still requires the relevant App Store or Google Play service.
Where should I place the phone?
For audio-only starts, place it safely beside and clear of the blocks. Secure the phone when using movement practice, and use a stable side-on mount for camera tools.
Are reaction and sprint times official?
No. RaceCue provides useful training measurements and estimates, not certified competition or photo-finish timing.
Can I use a Bluetooth speaker?
Yes. A speaker positioned near the athletes can make commands easier to hear while a coach observes from farther down the track. Bluetooth delay can vary by device.
