This app is called Auxo, and it completely redesigns the view when using the switcher. This app, which will require a jailbroken iPhone, really shows a great execution of what would be a welcome improvement to a future “official” version of iOS (maybe iOS 7).
Swiping to the reveal the audio controls provides neat functionality of volume and viewing the album art. Swipe further and you are presented with toggle controls for Bluetooth, Wi-Fi and more, plus there is a brightness slider. The latter of which is only accessible by digging into settings. The toggles allow direct access to the settings by simply selecting and holding that toggle. Plus, the toggles can be rearranged.
In the app preview, or multi-tasking tray, in lieu of app logos, you have a card view showing the state of each app. It is a feature that is obviously borrowed from webOS, but nicely executed. The gestures are multi-touch enabled too.
If you have a jailbroken iPhone, this app will be available in Cydia soon. It will only work on iOS 6 devices for now. Pricing for the feature is not known either. With this kind of talent working in the “shadows” of the jailbreak environment, one can see what can be accomplished with the iOS platform. Given that, by showing what can be done, great looking features like this do play against the age of the overall user experience of iOS.
