Relyne turns the workout history sitting in Apple Health into something you can actually find, map, and relive. Every run, ride, swim, hike and dive you have ever recorded becomes searchable in seconds, drawn on a single map, and tied to the photos you took along the way. Not a number on a chart. The morning it happened. And it all stays on your iPhone. FIND IT THE WAY YOU REMEMBER IT Type what you recall ("rainy run near the coast last spring") and Relyne's finder turns your words into filters: sport, place, weather, distance, date. It reads French and English, and it is fully deterministic, so it never guesses and never sends your words to a server. The same words always find the same outings. RELIVE YOUR PLACES Relyne quietly matches the photos already on your phone to the workouts you did, by time and place, entirely on the device. No image is copied. None is uploaded. Then, one ordinary morning, a year ago today resurfaces as a memory you can scroll through, and every memory it makes is kept in a gallery that grows with you. EVERY PLACE, ON ONE MAP Years of starts and finishes, clustered onto a single map of where your body has been, with a satellite globe a tap away. RECORDS THAT MEAN SOMETHING Your fastest 5K, 10K and more, found with a sliding window so a fast split inside a longer run still counts. Every record opens the exact workout and highlights the segment on the route. EVERY SPORT, NOT JUST STEPS Running, cycling, swimming, hiking, diving, rowing, skiing, strength and more. If Apple Health recorded it, Relyne can find it. BEYOND THE APP A memory on your Home Screen and Lock Screen, rotating through the day. A Photos-style carousel on Apple Watch, with complications for your watch face. And gentle, opt-in reminders (off by default) when a memory resurfaces or you set a new personal best. PRIVATE BY DESIGN Relyne runs on your iPhone. Apple Health and Photos are read only: the app never changes them. There is no account, no sign up, and no server. The App Store privacy label reads, simply, Data Not Collected. The only thing that ever leaves the device is an approximate location, sent to Apple to turn coordinates into a place name. Relyne is not a coach. It will never tell you to rest, push harder, or optimize. It looks back, not forward. It remembers, and you decide what it meant.
