Your location data never leaves your device. No analytics, no cloud tracking, no invasive permissions. What happens on your phone stays on your phone.
Save your favorite routes and use them without internet. Maps are downloaded locally, so your alarm works even in dead zones.
Smart background tracking ensures we only wake up your GPS when necessary. Save juice for your music.
No constant GPS polling
GPS wakes only when an active alarm needs location updates.
Adaptive check intervals
Far away = fewer checks, near destination = tighter checks.
