DestMate

DestMate is a private travel alarm app for buses, trains, and long rides. It listens to your route, watches your distance, and alerts through earphones or vibration so you wake up exactly where you need to be. Set a destination radius, enable earphone-only alerts, and rely on a smart fallback timer if GPS is spotty. Your location processes on-device for privacy, and you can share alarms with others via QR codes so everyone gets the same destination alert on their own phone.
