How it works

Android defaults to 15-25 volume steps. 32steps lets you set your own count by splitting each system step into smaller sub-steps using a gain offset through Android's DynamicsProcessing API (falls back to Equalizer on older devices). An accessibility service intercepts your volume buttons, and a foreground service keeps it running in the background. Works across all apps.

Sound Profiles

Pick your headphones from 6000+ models and the app corrects the sound based on measured data from AutoEQ. Save presets with different headphones and step counts. The headphone database updates automatically.

Requirements

Android 8+

Setup

Install the APK
Open the app, set your preferred number of steps
Follow the guided setup (accessibility service, overlay, battery)
Close the app and use your volume buttons

Permissions

Accessibility Service - intercepts volume button presses
Overlay - shows volume popup when you change volume
No internet - the app can't send or receive any data

On Android 13+, you may need to allow restricted settings first. Go to Settings > Apps > 32steps, tap the three dots in the top right corner, then tap Allow restricted settings.
