Pinping vs Sound Scope Analyzer

Pinping turns your iPhone into a smart location-based reminder system. Instead of time-based alarms you forget, Pinping alerts you exactly when you arrive near a place that matters. HOW IT WORKS Drop a pin anywhere on the map with a long press. Set a reminder radius — from 100 meters to 500 meters. Add a note and emoji so you instantly know what the reminder is about. Pinping notifies you the moment you step into that area, even when the app is completely closed.
