Link Alarm

This app connects two iPhones via Bluetooth and monitors their communication status. When you tap “Start Communication” on one iPhone, it starts Bluetooth communication with the other iPhone. If the Bluetooth connection is lost, an alarm notifies you and the app attempts to reconnect. If the connection is restored, the alarm stops and monitoring resumes. After the app has been running in the background for a long time, the connection may not be restored. For example, the app can be used to monitor two iPhones that you want to keep nearby, or to notify you when your child’s iPhone moves away.
