GhostDelta
Race Your Ghost
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
GhostDelta is a precision Apple Watch GPS recorder for outdoor sport: mountain biking, skiing and snowboarding, hiking, running, motorcycling, karting, boating and more. Record on your wrist. Analyse on your iPhone.
Race yourself. Pick any stretch of trail, road or track and GhostDelta times every run against your own best, live and sector by sector, with the gap on your wrist while you're still moving. Ride a loop and every lap is timed the moment you cross the line.
BEAT YOUR BEST
Every run is timed automatically against your personal best, split into sectors and sub-sectors, with a live gap that tells you whether you're up or down before you reach the finish. Mark the section once as a Stage (a descent, a climb, a favourite run of corners) from any recording on your iPhone, or on the go: press the Action Button to start and stop a new Stage mid-ride. From then on GhostDelta spots the start by itself, and your Stage Book keeps every record, including runs you did before you created it.
LAP TIMING
Every lap is timed and ranked, with sector splits and a live gap to your best while you're still on track. Save any closed loop as a Circuit: a kart track, a lap of the park, a training loop. GhostDelta can even spot a loop by itself. Session bests and all-time bests are tracked automatically.
FOLLOW ANY ROUTE
Head for tomorrow's campsite without splitting your GPX. Import a route, trim it to the start and finish you want, and drop named waypoints along it: a campsite, a lunch stop, a summit. On your wrist, see the distance, climb and descent to the waypoint you choose or to the finish, the elevation profile ahead, and the next climb with its gain and gradient. Press the Action Button for a timeline of every waypoint ahead and behind you: tap one ahead to navigate to it, or one behind to see how far you've come since. Off-route warnings bring you back.
