Granular Volume: Quiet Dial

Volume too loud even at the lowest setting, on calls, media, or notifications? Your phone or tablet stops at its hardware minimum. Granular Volume goes below it.

A small floating volume control appears above any app. Seven steps from no change down to a full 30 dB below your hardware minimum. One tap to move. Drag it anywhere on screen, tuck it to an edge, close it when you are done. Your position is saved.

This is a convenience utility, not hearing protection equipment. Actual loudness depends on your device and headphones, so use good judgment with volume changes.

LOWER THAN YOUR PHONE OR TABLET ALLOWS
Every other volume app goes one direction: louder. Granular Volume goes the other way. It reduces volume below the lowest step your device's hardware allows, using Android's audio engine, on phones and tablets alike. No root required. No volume button override. No system volume panel replacement. Just the quiet end of the dial, without touching anything else.

BUILT FOR TABLETS TOO
Tablets often have an even higher minimum volume than phones, especially through their built in speakers or over headphones. Granular Volume works exactly the same way on Android tablets as it does on phones, so tablet users get the same quiet floor.

A FLOATING VOLUME CONTROL, ALWAYS IN REACH
The control lives above whatever you are doing. Open any app, start any audio, and it is there when you need it. Drag it anywhere, or tuck it to an edge between uses. One tap closes it. Your last position is remembered next time.

QUICK SETTINGS TILE
Swipe down, tap once. Add Granular Volume to your Quick Settings panel and toggle the overlay on or off without ever opening the app. No shortcuts to set up, no widgets to place.

MADE FOR QUIET MOMENTS
- Phone and app calls (regular calls, WhatsApp, video calls) where the earpiece or speaker volume stays too loud no matter what
- Sensitive IEMs and high-sensitivity headphones, where even step 1 is too loud
- Tablet speakers and headphones, where the minimum step is often even louder than on phones
- White noise or lullabies for a sleeping baby, kept barely audible
- Late-night listening next to a sleeping partner
- Quiet rooms, libraries, open offices, and meditation
- ASMR and relaxation audio at a comfortable level
- Hearing aids and amplified devices where minimum system volume is too strong
- Anyone who searched for lower volume than the minimum Android setting

DESIGNED TO STAY OUT OF THE WAY
Granular Volume does not take over your volume buttons. It does not replace your system volume panel. It does not add an equalizer suite you did not ask for. It sits quietly on top as an overlay and does one thing: make the output quieter than your hardware minimum.

PERMISSIONS, EXPLAINED
- Display over other apps: required to show the floating volume control above your screen
- Modify audio settings: required to apply the volume attenuation
- Run a foreground service: keeps the control reliable while you listen
- Start on boot: so it is ready when you need it

Works on Android phones and tablets alike. If your minimum was always too loud, this is the volume you were missing.
