Loc is a free and open-source arrival reminder for Android. Choose a destination, set how close you want to be, and Loc alerts you when you get there.
- Multiple independently enabled reminders
- Background tracking while reminders are active
- Notification, vibration, or repeating alarm for each reminder
- Arrival radius from 100 m to 5 km
- High-speed crossing detection between GPS updates
- Place search, manual coordinates, and map selection
- Reusable saved places
- Light, dark, and system themes
Reminders, saved places, and preferences stay on your device. Loc has no accounts, ads, or analytics.
While reminders are active, Loc uses your location in the background to check whether you have reached a destination.
Place searches use Nominatim, and map tiles come from OpenStreetMap. These services receive the request data and standard network information such as your IP address.
