Volume profiles that switch themselves.
Set up a sound profile once — volume levels, ringer mode, Do Not Disturb — then attach it to a Bluetooth device. When your car stereo or headphones connect, SoundPilot applies the profile. When they disconnect, it can put things back exactly as they were.
SoundPilot has no accounts, no sign-in, no analytics, no ads, and no crash reporting. It does not request Android's internet permission at all, so it cannot send anything anywhere — your profiles stay on your phone. The full details are in the privacy policy.
SoundPilot is in closed testing ahead of its first Google Play release. This page will grow as the app ships.
