If you’ve ever fancied setting custom display brightness and/or speaker volume levels for individual apps before, then it’s your lucky day. A newly-released jailbreak tweak dubbed Appaze by iOS developer AnthoPak lets you do these things with ease.
As shown in the screenshot examples above, Appaze utilizes the Home screen’s native 3D Touch menus to function. Upon pressing firmly on an app icon to reveal its menu, users will find two new additions, including “Set custom brightness” and “Set custom volume” at the top of the list.
