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
• Seamless export to RaceApp.net race management
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.
REQUIREMENTS
• iPad or iPhone with iOS 18 or later (iPad recommended for larger display)
• RaceApp.net account for exporting results
• Tripod recommended for best results
• Bluetooth keyboard optional for hands-free operation

Ratings & Reviews
**Live mid-race review** — scrub back through earlier finishes and place marks while the race is still recording. Recorder and reviewer iPads stay in sync.
**Multi-iPad backup recording** — pair two or more iPads on the same race for redundant camera angles. Switch between views during review; drag panes to rearrange.
**Bib-number marking** — assign athletes to marks by bib number with automatic name lookup, alongside or instead of lane assignment. Per-race mark mode (Lanes / Bibs / None) persists.
**Spectator timer screen** — open the iPad's `/timer` URL on any device on the local network to show a live race clock plus provisional results. Times now display naturally ("10.12" instead of "00:10.12") for sub-minute races.
**Laptop archive download + offline review** — pull a race archive to your laptop and review it in the browser without keeping the iPad nearby.
**Smoother video review** — triple-buffered primary video for flicker-free frame stepping across segments. Frame-accurate marks at 60, 120, or 200 fps. Configurable arrow-key scrub speed (default 1.5×).
**Reliability fixes** — single-source-of-truth race files for consistent state across review, export, and live mode. Robust chunk rollover for long live recordings. Lane-color bracelets in the assign UI. Backup audio capture of the starting sound. Larger LISTENING banner while waiting for the gun.
