Many developers informal applications for iOS draw inspiration from desktop operating systems. So there were a theme in the style of Snow Leopard and the Mavericks, tweaks SwipeSelection, AltKeyboard and others. By the same token, a new add-VolumeStatus.
Developer VolumeStatus decided to add to the status bar iOS volume level indicator, similar to how it is implemented in Mac OS X. This allows the user always knows the level of sound in the system without causing any control point or by clicking on the volume buttons. As a result, the chance to leave the iPhone in silent mode tends to zero.
Developer Tools warned that VolumeStatus not tested on 64-bit models, iOS-devices (iPhone 5s, iPad Air and iPad mini). Work on these gadgets can not be guaranteed. Also not without annoying limitations: icon tweak responds only to software controls iOS - iPhone pressing physical buttons have no effect on the meter reading.
VolumeStatus available for download free of charge. Jailbreak iOS 7 and install it on the device catalog Cydia for access to the entire database of tweaks you can use the utility Pangu .
