The smallest change and available range 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 with a name and icon, widgets, and Shortcuts. You can also turn Safety Max on or off for free. Pro unlocks additional designs, including Zen Garden and Sky, up to six presets, changes to the legacy widget’s dedicated volume value, and changes to the Safety Max limit.

Safety Max When enabled, Safety Max limits volume values set through the app. A brief notice appears on the main screen when the requested volume exceeds the limit. Changing the limit requires Pro. Sky Switch between Sunrise and Moonrise, then drag up or down on the sky to adjust the 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.
