New on iPhone
Timer, Judge and Buoys now feel native on iPhone
The main race workflows move from the wrist to the phone when you need a larger, more detailed control surface before, during or after the start.
Mode Judge
Control the race sequence
Officials can run standby, countdown, flags and start controls from a larger, more readable screen.
Mode Buoys
Build the course visually
Set gybes, leg distance, orientation and wind angle while previewing a real buoy layout.
Mark & Recover
Drop a mark. Find it again.
Save an exact point and navigate back to it with confidence when conditions, distance or visibility make recovery harder.
Product experience
Made to feel calm, precise and athletic
The experience is intentionally split between wrist-first action and iPhone-first reflection.
