iPhone 6 with a 4.7-inch screen and iPhone 6 Plus with a display diagonal of 5.5 inches was released in 2014. The device with a large screen allows you to run all apps designed for previous models. However, some of the oldest programs, unadapted developers continue to open in 3.5 inch format on the display at the top and bottom remain black bands.
Several years passed after switching on the Apple displays with the new permission, but some apps from the App Store still not adapted to the large screen smartphones. Unofficial add-on called PerfectFit solves this problem.
PerfectFit from programmer Tony Kraft works with apps that are not optimized for screens with permissions 1334 x 750 pixels and 1920 x 1080 pixels. Once installed on the device you need to go to a new section of the OS settings and activate the radio button in front of any of them.
The Creator of the add-in has implemented “smart” system of selection of the installed software, so the list has only non-adapted programs. If the switch in front of any of them, the app will open in full screen.
If the user launches the utility that opens not in full screen format, PerfectFit independently propose to “stretch” its interface.
PerfectFit works on the principle of the tweak FullForce, but adapted for iOS 10 and the latest iPhone and iPad models. You can install it via Cydia from the standard repository BigBoss, tweak free.
