Frequently Asked Questions

How do I set a location alarm?

Open NapStop, tap the search icon or "Search Destination" button, type your destination, and select it from the results. The alarm will start monitoring your location automatically.

Does NapStop work in the background?

Yes! NapStop uses background location tracking to monitor your position even when your screen is off or you're using other apps. Make sure to grant "Always" location permission for the best experience.

What are the approach and arrival alerts?

• Approach Alert: Notifies you when you're getting close to your destination (default: 2 km). This gives you time to prepare.
• Arrival Alert: Rings the alarm when you've reached your destination (default: 500 m). This is the wake-up alarm.

What if I pass my stop?

NapStop includes overshoot detection. If it detects you're moving away from your destination after being close, it will alert you that you may have passed your stop.

Can I adjust the alarm radius?

Yes! Go to Settings to customize both the approach radius (500 m - 5 km) and arrival radius (100 m - 2 km) to match your needs.

Will the alarm work in silent mode?

Yes. NapStop uses a critical audio session that can play alarms even when your phone is in silent mode.

Does NapStop work on the subway?

NapStop includes a subway fallback mode using CoreMotion. When GPS signal is lost (such as in tunnels), it estimates your position based on your last known speed and direction.

How do I cancel an active alarm?

Tap "Cancel Alarm" on the monitoring screen, or dismiss the alarm when it rings.

Does NapStop drain my battery?

NapStop is optimized for battery efficiency. It uses balanced location accuracy and only activates high-accuracy tracking when you're approaching your destination.
