Run Offline. Keep Your Data.
Stray is a tracker that never phones home. Run, walk, hike or ride — every route and every split stays on your device. No leaderboard. No followers. Just the road and the outing you chose.
How it works
One Tap. Then Go.
-
Pick Two Things
What you're doing — run, walk, hike or ride — and what it's judged on: a duration, a distance, or nothing at all. No feed to scroll.
-
Run Dark
GPS on, radio off. Distance fills the screen, with pace and time underneath — readable mid-stride, in the rain.
-
Keep It
It lands in your history on this phone. Export a GPX whenever you want. Delete anything in one tap.
The Deal
We Don't Want Your Routes.
Most fitness apps are data businesses wearing shorts. Stray isn't. There is no server to send anything to.

Loud
A local music player. No cloud. No ads. No account.
Point it at a folder and it plays it — your own MP3s and FLACs, with their real tags and covers. Same deal as Stray: nothing phoning home.
