GHOSTDELTA
EVERY SESSION. EVERY LAP.
GhostDelta is a precision GPS tracker for outdoor sport — mountain biking, skiing and snowboarding, hiking, running, motorcycling, karting, boating. Record on Apple Watch. Analyse on iPhone.
Race yourself: live timing against your own records, sector by sector, with the delta on your wrist while you're still moving.
Stages
Timed sections, detected automatically
Define a Stage on any trail, road or track. Every Run is timed against your best with sector and mini-sector precision, and your Stage Book keeps every record.
Circuits
Every lap scored as you cross the line
Save any closed loop as a Circuit. Live lap timing with sector splits, session bests and all-time bests — and the delta while you're still driving it.
Navigation
The route on your wrist
Import a GPX route, drop named waypoints, and follow it from the Watch — distance remaining, the elevation profile ahead, the next climb with gain and gradient.
