The complete start line
A configurable starter, reaction lab, camera tool, and session companion.
RaceCue is built for sprinters training on their own, athletes working with a coach, and groups running repeatable starts. The main dial keeps the sequence simple while deeper controls stay close when they are needed.

Everything in one training app
From the first command to the session review.
Use only the starter, or build a complete practice around reaction, recording, pressure, repetitions, and coach feedback.
02 / REACTION
Reaction Practice
Run movement or touch drills, estimate the response after GO, flag early movement, compare recent attempts, or use the main sequence while the stopwatch continues through the sprint.
03 / CAMERA
Camera Start Detection
Mount the phone side-on, use the front or rear camera, and optionally start hands-free when the athlete settles. Camera reaction timing can estimate first movement after GO.
04 / VIDEO
Automatic Start Video
Prepare either camera once and record each start from before the commands until shortly after GO. Preview the latest repetition and save only the useful videos.
05 / PRESSURE
Competition simulation
Add real track ambience and random distractions while official commands remain dominant. Practise recalled starts, random stand-up commands, gun misfires, and changing Set holds.
06 / SESSIONS
History and progress
Run structured repetitions with recovery countdowns, create coach sessions with athlete and lane assignments, add notes and manual times, then review local history or export CSV results.
Sound, light, and display
Make GO clear for the setup in front of you.
Recorded soundCompetition pistols, track starters, dry reports, loud signals, and a hand clap.
Visual cueFull-screen white, green, amber, or blue flash with adjustable duration.
Phone torchUse the supported rear-camera torch as a visible GO cue when the camera is not already in use.
Stage displayChoose Classic, Track Lanes, Signal Timer, Command, Eclipse, or Wave visuals and five athletic themes.
Recorded starter voices
Train in 15 starter languages.
Starter audio and the app interface can be selected independently. Use English commands with Arabic menus, or Turkish commands with an English interface. Arabic includes a right-to-left layout.

Train Your Way
From solo block work to coach-led groups.
Solo Athlete
Place RaceCue near the blocks and practise independently using realistic commands, reaction tools, camera detection, Start Video, competition pressure, and structured repetitions.
Bluetooth Speaker
Play commands through a nearby speaker when more volume is useful for outdoor, windy, or group sessions.
Bluetooth audio delay varies by device and speaker. Use the iPhone speaker for precision reaction work unless the setup has been calibrated.
Coach Starter
Give a coach direct control of On Your Marks, Set, GO, Stand Up, Recall, and Misfire for individual athletes or groups.
Structured Repetitions
Choose the number of starts, recovery duration, and sequence settings. RaceCue guides the session and records completed, interrupted, and false-start attempts.
Coach Sessions
Add athlete names and lane assignments, run starts, stop the training timer, enter externally measured times, attach notes, and export local CSV results.
Suitable for: block starts, acceleration runs, flying sprints, 10–60 m start work, 100 m and 150 m training, speed endurance, relay practice, and repeated technical starts.
Feature status
Clear about what is ready and what comes next.
RaceCue is still in development. These labels describe the current project rather than promising unfinished features.

Android real-device validation
The Android project exists, but its camera, audio, recording, permissions, and purchase flows have not yet completed real-device beta validation.
