Bluetooth Volume Manager remembers volume levels for each of your Bluetooth devices and reacts when they connect or disconnect.

Features: * Set music, call, ringtone, and notification volumes per device
* Auto-send media commands like Play or Next
* Launch apps on connect
* Keep screen awake
* Lock volume levels
* Restore volume after disconnect

No ads, no tracking. Open-source.
Some extras require a paid upgrade to support development.

Note: This app can't boost volume or override system volume limits.

Permissions: * Internet – for optional bug reports
* Bluetooth – to detect device connections
* Audio settings – to change volume
* Boot – to restore settings after reboot
* Wake lock – to keep screen awake or fix Samsung bugs
* System alert window – to auto-launch apps (Android 10 only)

Download Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
