## What is Geo Fencer?

Get alerted the instant you enter or leave any area you define. Draw a virtual boundary around a neighborhood, job site, or school zone — and Geo Fencer+ notifies you automatically when you cross the line. Works in the background so you never miss a boundary crossing.

Key Features:
- Create circular geofence zones
- Enter/exit notification alerts
- Custom radius from 50m to 5km
- Multiple active geofences
- Real-time distance to boundary
- Location history log
- Background monitoring support

Useful for parental monitoring, work check-in zones, travel alerts, and location reminders. GPS accuracy may vary by environment.
