Every mile, beautifully simple.
Trailtrace is a fast, clean GPS tracker for iPhone — run, walk, bike, ski, or head off-road. Full-screen maps, a blue trail of everywhere you've been, and live distance, pace, and speed. Nothing you don't need.
Made with care by a family business in Washington State, USA.
Full-screen map
A live map fills the screen with a blue line tracing your whole route as you go.
Live metrics
Distance, current pace, current speed, and time — glanceable, never cluttered.
Any activity
Run, walk, bike, ski, off-road — pick your activity, then start, pause, and stop. That's the whole app.
Private by design
Your routes live on your device and your own iCloud. We never store your location.
Your data stays yours.
Trailtrace keeps your activity history on your iPhone and — when you turn on iCloud sync — in your own private iCloud, so it follows you across your devices. Alpine Lake Systems never receives, stores, or sells your location. You can even see your history here on the web: your browser reads it straight from your iCloud, and this site stores nothing.
