Fine Volume Control

Fine-tune iPhone system volume with 1% controls, presets, and a widget. This is not a volume booster.

Fine Volume Control is not a volume booster. It is a tool for adjusting iPhone system volume in small steps from within the app.

【Key features】 • On-screen controls in 1% steps • Precision controls in 0.1% steps • Request low volume levels in finer steps than the side buttons • Mute • Presets for frequently used volume levels • Color customization for the standard design • Home Screen widget on iOS 18 or later

The app sends volume values to the iPhone in 1% or 0.1% steps. The smallest change and available range that are actually applied depend on the iPhone and the connected earphones, speakers, or other audio device. The side buttons continue to use the iPhone’s standard volume steps.

【Free and Pro】 The free version includes the standard design, color customization, one preset, and the widget. Pro unlocks additional designs including Zen Garden and Living Horizon, up to six presets, widget preset customization, Safety Max, and more. Additional designs require Pro.

【Living Horizon】 Switch between Sunrise and Moonrise, then drag up or down on the sky to adjust the volume.

【Widget】 The widget requires iOS 18 or later. Tapping the widget opens the app to apply the selected volume.

【Bluetooth and external audio devices】 Depending on the device and connection method, fine values requested by the app may be applied in larger steps.
