FAT Timer
Fully Automatic Race Timing
Free · Designed for iPad. Not verified for macOS.
The official companion app for RaceApp.net - transform your iPad into a Fully Automatic Timing (FAT) system. Record the finish line
in 240fps slow-motion, mark athlete times frame-by-frame, and export results directly to your RaceApp.net meets.
PERFECT FOR
• Track & field meets
• Cross country races
• Swimming competitions
• Any timed sporting event
HOW IT WORKS
1. Mount your iPad with a clear view of the finish line
2. Start recording when the race begins (manual, sound-activated, wireless mic, or network remote control)
3. Review the video and mark each athlete's finish time — on the iPad or from any browser on the local network
4. Export times to your RaceApp.net meet with one tap
KEY FEATURES
• Record at up to 240fps for ~4ms timing precision
• Sound-activated start detects the starter's gun
• Frame-by-frame video scrubbing for precise marking
• Pause and resume recording for longer races
• Local video storage - your recordings stay on your device

MULTI-PERSON WORKFLOW
Split the work at a busy meet. One person operates the camera while others review video and mark finish times from any laptop,
tablet, or phone on the same network. The built-in review server streams race video, syncs marks in real-time across all devices, and
supports multiple simultaneous reviewers. Optional password protection for shared networks.
REMOTE CONTROL
Control the timer from a phone or second device using the browser-based remote at /remote. Start, stop, pause, select races, and
create new heats — all without touching the iPad. Bluetooth keyboard support lets you operate the timer completely hands-free.
FREE TO USE
Recording, marking finish times, and exporting up to 3 results per race is completely free. Export unlimited results with a FAT
Export subscription ($99/season), available for individuals or teams.

Ratings & Reviews
Multi-Person Timing Workflow — One person operates the camera and timer on the iPad while others review video and mark finish times from any browser on the local network. The built-in review server streams race video, syncs marks in real-time, and supports multiple simultaneous reviewers. Password protection available for shared networks.
Bluetooth Keyboard Controls — Operate the timer hands-free with a connected keyboard. Return to start/pause/resume, S to stop, Escape to cancel, L for listen mode. Works through all screens including the race review overlay.
Remote Control — Start, stop, and manage races from a phone or laptop browser at /remote. Race picker remembers your position, create new races without touching the iPad, and keyboard shortcuts match the iPad controls.
Lane Color Coding — When lane colors are configured in RaceApp.net, colored indicators appear on lane picker buttons and mark lists for quick visual identification by wristband color.
Bug Fixes & Improvements:
- Camera focus restores automatically after reviewing a race
- Marks can be placed immediately after recording
- Stop while paused now saves the race correctly
- Export times rounded to hundredths for standard track timing
- Faster sound-start with no keyboard delay
- Video streaming stability for longer review sessions
- Duplicate lane prevention in web review
