The most expensive software in the appstore.

The most expensive software in the appstore is Vizzywig 4K.

This photography application called Vizzywig 4K is the first application supporting 4K video shooting on the iOS platform.

Corresponding to its high price, Vizzywig 4K also has strict equipment requirements: it only supports iPhone 5s, the system must be iOS 7, and does not support the upcoming iOS 8.

The reason why only iOS 7 is supported is mainly because of the shooting principle of this application, that is, the video is synthesized by taking 24 photos a second, and the reason why iOS 8 is not supported is because of the continuous shooting mode of iOS 8, that is, taking 10 photos a second, which obviously conflicts with Vizzywig 4K.

4K video shot by Vizzywig 4K App:

Because only iOS 7 system supports this kind of extreme speed continuous shooting, users can't upgrade the system at will. In addition, the iPhone 6 of iOS 8 does not need this App. IOS 8.0 will set a limit of only 10 for the shutter speed of the camera, so friends who want to buy or buy this app should remember not to update it.
