Hybrid Geofencing and Time-Based Reminder App

Android | Java | Geofencing | Google Maps SDK | AlarmManager

Overview

This project is an Android application that provides reminders based on both location and time. The system combines geofencing technology with time scheduling to ensure that reminders are triggered when either the user reaches a specific location or the scheduled time occurs.

The application improves traditional reminder systems by introducing a dual-trigger mechanism, making task notifications more reliable and context-aware.
