RaceCue Pro01 / START POSITION
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.
- Athlete focus
- Move into your blocks, place your hands and become still.
- RaceCue
- Controls the selected On Your Marks-to-Set interval before giving the next command.
How it works
Set up once. Focus on the start.
RaceCue guides the sequence from preparation to review, whether you are training alone or running starts for a group.
02 / POSITION
Place the phone safely
Leave it beside the blocks for audio, secure it for movement practice, or mount it side-on for camera Start Detection or Start Video.
03 / RUN + REVIEW
React, record, repeat
Follow On Your Marks, Set and Go, then review reaction estimates, video, sprint times, notes, and session progress.
Historic Finals
Step into the start of an iconic final.
Practise with the command timing of Olympic and World Championship finals. Meet the athletes in their lanes, follow the starter, then reveal the complete official results row by row.

Reveal the whole field
See every athlete’s official finishing result, revealed one row at a time. Your optional sprint timer remains visible beneath the results.
Timing recreations are based on observed race footage. Athlete lineups and results are checked against official records.
Try Historic Finals with your free Premium trialRace pressure & sounds · Premium + Pro
Recreate the uncertainty of competition.
The unexpected is hard to rehearse with a predictable start. Practise holding your focus through changing Set delays, recalled starts and interruptions, with a race-day soundscape you control.
Practise false-start recalls
Choose how often a start is recalled, the starter says Stand Up, or the gun misfires. Settle again and wait for the actual signal instead of guessing the gun.
Build your start-line sound
Choose starter voices and languages, recorded pistol sounds or a hand clap. Add stadium atmosphere and trackside distractions with separate controls; starter commands and the gun take audio priority.
Pressure and sound customisation are included in Premium and Pro. Simulated recalls are separate from early-movement feedback using prepared camera detection (Premium) or a supported Apple Watch (Pro).

Train the response to GO
Turn every start into useful feedback.
RaceCue gives every repetition a clear sequence, then estimates first movement through phone motion, touch, a mounted camera or supported Apple Watch. Recent results make it easier to practise responding quickly without anticipating the signal.
At homeRehearse command recognition, posture, and first movement in a safe clear space.

01Sprint timeriPhone · Android
Keep the phone with the coach and put a Bluetooth speaker near the athlete. Enable Sprint timer, start the sequence, then tap Stop Timer at the finish. The app timer starts at Go; the finish is stopped manually. Bluetooth audio delay varies.
02Visual Start SignaliPhone · Android
Leave the phone near the athlete, with its rear light facing the coach. In Start settings, choose Flash at Start or Light Off at Start. Start your own stopwatch when the light flashes or goes out, then stop it at the finish. Preview visibility first; stop camera detection or recording before using the rear torch.
03Camera & videoPremium
Start Detection can recognise the athlete moving into position and optionally estimate reaction from the camera. Start Video records each repetition instead. Choose front or rear camera; RaceCue only activates the mode you explicitly prepare.
04Apple WatchPro
Start from Apple Watch. Get wrist-movement reaction feedback, early-movement alerts and a stopwatch that starts with the gun. Independent starts use distinct Marks, Set and Go tones. Apple Watch requires a paired iPhone and Pro or an active training trial. Reaction feedback is a training estimate.

How do I use RaceCue with Apple Watch?
With RaceCue 1.3 on your paired iPhone and Watch, open RaceCue on both devices, choose Apple Watch under Wearables and enable wrist-movement reaction feedback if you want it. Watch training requires Pro or an active training trial. Phone-start commands play on iPhone; independent Watch starts use distinct tones. Apple Watch support is available now with Pro.
Do I need Pro if I already own Premium?
Phone Premium keeps your existing phone features. To add Apple Watch, choose monthly Pro, full Pro once, or the separate one-off Premium-to-Pro upgrade. Monthly Pro includes Premium and renews until cancelled. If it expires, any phone Premium you bought separately remains yours.
What about Wear OS, Garmin and Photo Finish?
Wear OS and Garmin are in testing for later releases. Two-phone Photo Finish is also in private testing and is not part of this Apple Watch launch. Explore the Photo Finish preview.
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.
