Drop Sound app for iPhone and iPad

Imagine walking around with your headphones on and discover sounds recorded and dropped by other users. Like echos that last forever.

Record and drop your own recordings anywhere in the world for other people to hear them when they walk by the location you dropped your sound recording.

This app runs in the background so you can use your iPhone as usual and walk around (with your headphones on).

Features:
- record and drop a sound (maximum of 6 seconds) and drop it on your current location
- add a short description (optional)
- specify a radius (in meters) at what distance the sound plays when other users are near (optional)
- mark the sound private if only you want to see and hear your sound
- start the app and let it run in the background so you hear sounds other users dropped even when you are not actively using the app

Note: For this app to work in the background it needs authorization to use location services at any time.
