Everything you need.
Nothing you don't.

Privacy First Architecture

Your location data never leaves your device. No analytics, no cloud tracking, no invasive permissions. What happens on your phone stays on your phone.

Favorites Work Offline

Save your favorite routes and use them without internet. Maps are downloaded locally, so your alarm works even in dead zones.
