GhostDelta

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. Define a stage on any trail or track and GhostDelta times every run against your best — live, sector by sector, with the delta on your wrist while you're still moving. Save a circuit and every lap is scored the moment you cross the line.

STAGES A Stage is a timed section of trail, road or track — a descent, a climb, a favourite corner sequence. GhostDelta detects entry automatically and times every Run against your best, sector by sector, with mini-sector precision. Your Stage Book keeps every record.

CIRCUITS Save any closed loop as a Circuit — a kart track, a lap of the park, a training loop. Every Lap is timed and ranked, with sector splits and a live delta while you're still driving it. Session bests and all-time bests, tracked automatically.

NAVIGATION Import a GPX route, drop named waypoints, and follow it from your wrist: distance travelled and remaining, the elevation profile ahead, the next climb with gain and gradient. Off-route warnings bring you back.
