Reliable timing and team sync for relay races.
Relayyy is built for multi-leg team races — one-tap exchange zones, offline-first, and live sync across every van when you have service. Tuned first for the Blue Ridge Relay, built to handle whatever you run next.
No newsletter. No drip. One email when TestFlight opens, one on launch day.
What it is
Relay racing is a coordination problem, not a stopwatch problem.
Twelve runners. Two vans. Thirty-six legs across a mountain range, overnight. Exchange zones in cell-signal dead spots. Captains trying to hold a spreadsheet together on three hours of sleep.
Most timing apps were built for single-runner races. Relayyy is built for multi-leg team races — the kind where you hand a slap bracelet to someone in the dark, remember who's next, and keep the other van informed without cell service.
Tap once when your runner leaves. Tap once when the next one starts. Relayyy keeps the clock, the order, and the team in sync — and fills in the story once service comes back.
Race-day ready
Minimal cognitive load at 3 a.m. on a mountain.
Built around four principles: Race-Day Reliability, Sub-Second Timing, Minimal Cognitive Load, and Offline-First.
Offline Timing
Sub-second splits whether or not you have signal. Every exchange, every leg — captured locally first, synced when bars return.
Team Sync
Multi-device sync across every van. Captains see leg updates from the course; runners see who is up next on their own device.
Live Activities
Current leg, runner on course, and next exchange time live on the lock screen so you never miss a handoff.
Built for 36 Legs
Tuned first for Blue Ridge: 208 miles, 36 legs, 12 runners, 2 vans, overnight. More relays rolling out after launch.
