NapStop is the GPS location alarm designed for commuters who want to rest during their journey. Whether you ride the bus, train, or ferry, NapStop watches your location and wakes you up before you reach your stop. HOW IT WORKS Set your destination, and NapStop monitors your position using GPS and geofencing. When you approach your stop, you get a gentle heads-up. When you arrive, the alarm rings loud and clear, even in silent mode. KEY FEATURES GPS Geofencing NapStop uses CoreLocation to track your position with precision. Set any destination by searching for a place, and the app creates a virtual boundary around it. Approach and Arrival Alerts Get a two-stage warning system. The approach alert notifies you when you are getting close, giving you time to gather your things. The arrival alarm rings when you have reached your destination. Overshoot Detection If you pass your stop without noticing, NapStop detects that you are moving away and triggers an alert so you can take action quickly. Works in the Background NapStop continues monitoring even when your screen is off or you are using another app. Lock your phone, read a book, or take a nap with confidence. Silent Mode Bypass The alarm plays at full volume even when your phone is set to silent. You will not sleep through your stop. Live Activity See your remaining distance right on the Lock Screen and Dynamic Island. No need to unlock your phone to check your progress. Subway and Tunnel Support When GPS signal is lost in tunnels or underground, NapStop uses CoreMotion to estimate your position based on your last known speed and direction. Customizable Radius Adjust the approach radius from 500 meters to 5 kilometers and the arrival radius from 100 meters to 2 kilometers to match your travel needs. Alarm History Review your past trips and alarm records anytime. Favorites Save your frequent destinations for one-tap alarm setup.
