32steps — Open Source Productivity App

Override Android's default volume steps with custom step counts. Includes 6000+ headphone EQ profiles and a 10-band graphic equalizer. No root required.

32steps splits each system volume gap into smaller sub-steps by applying a gain offset through DynamicsProcessing (or Equalizer on older devices). An accessibility service intercepts volume buttons and a foreground service keeps it running in the background. Works across all apps. No root, no internet.

Sound profiles: select your headphones from 6000+ models and the app applies an EQ correction based on measured frequency response data from AutoEQ. Save multiple presets with different headphones and step counts. The database is updated automatically.

Graphic equalizer: 10-band graphic EQ to create custom headphone profiles or fine-tune existing AutoEQ profiles. Reset to original AutoEQ defaults anytime.
