About

Tracker

Record every run, ride, hike and ski tour with precise GPS — on iPhone and Apple Watch. No account, no subscription. Tracker is built for athletes who want to decide for themselves where their data lives. Your tracks are kept as files on your own device. There is no Tracker account and no server storing your activities. Want to send a workout to Strava, or keep it in Apple Health? That happens only after you tap. WHY TRACKER • No subscription — Pro is a single purchase • No account, nothing to sign in to • Your tracks stay on your own device • Works on iPhone and Apple Watch • Available in English, Dutch, German, French and Spanish RECORD EVERY WORKOUT Capture distance, pace, time, elevation and your full route. Pick your sport on the redesigned start screen — running, walking, cycling, skiing, swimming, rowing or something else — and head outside. While recording you can zoom in, explore the map and return to your own location with one tap. Your music keeps playing while Tracker keeps recording in the background. PHOTOS ALONG YOUR ROUTE Take photos from inside the app while you are out. Each one is pinned to the spot where you stood and shows up as a marker on your map afterwards. So you see not only how fast you went, but where you were. TRAIN SMARTER WITH PRO • Build interval workouts and get spoken cues along the way • See how long you spent in each of the five heart-rate zones, and set your maximum heart rate • Compare activities and discover your best efforts with Personal Records • Transfer recordings from your Apple Watch to your iPhone • Back up to your own iCloud and restore onto a new device YOUR PROGRESS, BEYOND THE APP Follow your iPhone recording on the Lock Screen and in Dynamic Island. Put your latest activity on your Home Screen as a widget, start a recording with Siri and Shortcuts, or find a saved track with Spotlight. Pro adds widgets for weekly progress and personal records, and lets you start saved workout plans with your voice. MADE FOR APPLE WATCH Start, pause and stop straight from your wrist. Your Apple Watch records on its own, even with no iPhone nearby. The controls are large and clear, and a confirmation always appears before a recording stops — so you never end one by accident. WORKS WITH APPLE HEALTH Your sessions are written to Apple Health as workouts, with distance, active energy and your route. Your rings and your activity history stay accurate without you doing anything twice. A LITTLE ENCOURAGEMENT Choose a weekly summary, a reminder when you have not recorded for a while, or a nudge while your streak is alive. With Pro you also hear about every new personal record. All notifications are off by default — you switch on what you want. SHARE WHEN YOU CHOOSE Upload an activity to Strava with Pro, from the app or through Shortcuts. You decide which ride or run you share, and when. PRO IS A ONE-TIME PURCHASE No subscription, no monthly fee. Already own Pro? Every new Pro feature in this version is included, with nothing more to pay. Simple. Private. Made for the outdoors. Pick your sport and record your next session with Tracker. Requires iOS 26 or later. The Apple Watch app requires watchOS 26 or later.
