Every run you record becomes a ghost — a replay of the exact runner you were. Lace up, pick one, and race it. GhostLoop isn't about competing with strangers on a leaderboard. The only person you're chasing is the one you were last Tuesday. And you'll know exactly where they are the whole way. RACE YOUR PAST SELF • Every recorded run is saved as a ghost you can race any time • A live gap shows whether you're ahead or behind, meter by meter • Hear it happen: spoken splits, pace, and the moment your ghost passes you • Save your favorite routes as loops and build a library of rivals TRACK IT ANYWHERE • Outdoor GPS with map-matched routes and elevation • Treadmill mode: race indoors with no GPS, using your own calibrated stride • Rides and swims import from Apple Health — pace in min/100m for the pool • Apple Watch app: start a run, walk, or pool swim and see your ghost gap on your wrist • Auto-pause when you stop, auto-resume when you go SEE YOURSELF GET FASTER • Weekly and monthly trends, training load, best weeks, longest runs • Run streaks with rest days that don't break the chain • Elevation profiles and 3D route views • Personal records that only compare like with like — a bike ride never fakes a running PR RUN WITH YOUR CREW • Add friends and see their step counts on a live club leaderboard • Create step challenges — daily, weekly, monthly • Send a ghost to a friend so they can race your loop on their own feet • Ghost runners fill out the board so it stays competitive from day one YOUR DATA, YOUR CALL • Export any activity as GPX; import your history from other apps • Shared route images hide the start and end of your run • Detailed Health records stay on your device; only daily step totals and challenge progress sync to people you accept Outmove yesterday. Apple Health is used to read your step counts and import your own workouts. Location is used to track your route while you run. GhostLoop never sells your data.

There's a kind of meditation app that wants to be part of your life. Moss just wants to get out of the way. Pick a duration. Choose an ambient sound, or silence. Begin. Everything else (session log, streaks, mindful minutes) stays quietly on your device, private and unhurried. Now on Apple Watch, too. Start a session right from your wrist, pick your own duration, and it logs back to your phone automatically. After a session, if you want, leave a quick note on how you felt. Entirely optional, and easy to turn off if it's not for you. No guilt if you miss a day. No badge pressure. Just a still place to return to whenever you're ready to breathe. Moss is for people who already know why they want to meditate. It just makes it easier.
