About this app

Bluetooth Brain automatically applies your preferred volume and brightness when your headphones, car or speaker connect. When they disconnect, your old settings come back.

🧠 HOW IT WORKS

1. Pick your Bluetooth device
2. Set the levels you want for it
3. That's it. Your settings apply every time it connects.

✨ FEATURES

- A separate profile for each device
- Your previous settings return when a device disconnects
- With several devices connected, the last one takes over. When it leaves, the previous one's settings return; when all leave, yours do.
- Smart device detection: tells audio devices apart from devices without sound, like smartwatches
- "This device has a speaker" option for smartwatches with a speaker
- Works in the background, light on battery

⭐ PREMIUM

The free version sets media volume for one device. Premium adds:

- Unlimited device profiles
- Ring, notification, alarm and call volume
- Screen brightness
- Signal strength gauge for BLE devices
- Night schedule: different levels during the hours you choose
- Ad-free experience

👍 EXAMPLES

🚗 Car: volume to 80% on connect
🎧 Headphones: 50% by day, quieter at night
🔊 Speaker: a different level for each room

💡 TIPS

- Android 17 and later: if the app asks to link with your headphones, tap "Allow". This lets it work in the background.
- Xiaomi, Redmi and POCO: turn on Autostart for Bluetooth Brain in your phone's settings.
- Night schedule is applied at the moment of connection. If you change it, reconnect the device.

🔒 PRIVACY

Your profiles are stored only on your phone. Ads in the free version are served by Google AdMob.

What’s new

What's new in 1.10.0

🎧 A one-tap way to let Bluetooth Brain work in the background on Android 17 and later — the app now asks Android for permission using your headphones, instead of sending you into battery settings.
↩️ You can undo that permission any time from Settings, where the app also shows you which device it is linked to.
✨ Small polish under the hood so the app draws correctly on the newest Android versions.
