Six streams, one screen
Media, ringtone, notification, alarm, system and in-call audio — each on its own slider, in sync with the hardware volume keys.
Volume booster
Up to +15 dB of extra gain on top of the system maximum, using Android's own loudness effect. Your level is remembered.
One-tap profiles
Silent, Vibrate, Normal, Loud and Outdoor — five presets that set every stream and the ringer at once.
Nothing else
No launcher, no wallpapers, no search bar, no ads, no trackers. The app does not even ask for internet access.
Listen responsibly
The booster raises playback above the normal system maximum. Sustained high volume can damage your hearing, and heavy boost can distort small speakers.
The booster relies on a hardware audio effect. A small number of devices and custom ROMs refuse to attach it; on those the app says so and disables the slider.
