Precision timing.
Built for open water.
RacerTime combines race countdowns, buoy navigation, GPS performance analysis, heart rate and maneuver detection into a single refined experience for serious water sports athletes.
A premium race toolkit for demanding conditions
Designed for water, motion and clarity — with a visual language that feels at home on both Apple Watch and iPhone.
Racing Timer
Countdown control through the Digital Crown for wet and demanding conditions where touch interactions become unreliable.
Judge Mode
Independent race sequence control for officials directly on Apple Watch, with distinct colors and purpose-built timing flow.
Buoy Guide
Configure real courses with 2–5 buoys, downwind angles and wind direction to navigate each mark precisely.
Performance Analysis
Review session maps, charts, speed metrics and long-term trends on iPhone after every session.
Maneuver Detection
Automatic detection of tacks and gybes in supported sailing disciplines, including successful and failed attempts.
Optional iCloud Backup
Sign in with Apple only if you want backup in your personal iCloud. The app remains fully usable without sign-in.
Made to feel calm, precise and athletic
The experience is intentionally split between wrist-first action and iPhone-first reflection.
On the Watch
Immediate, tactile control for starts, buoy courses and race workflows. Information stays glanceable, minimal and resilient in motion.
On the iPhone
A richer analysis layer for route review, speed overlays, session history, charts, heart rate and maneuver insights after the race.
Designed for clarity
A visually calm interface and focused information hierarchy built to be readable in dynamic outdoor conditions.
Disciplines supported by RacerTime
Optimized for a range of sailing and training contexts, from wind-powered disciplines to complementary land sessions.
