If you’re tired of non iPhone 6/6+ apps getting into zoom mode whenever you open them, BigBoss repo has the ForceGoodFit tweak which forces older apps UIs to fit into the screen correctly, the way they are supposed to instead of just zooming in. It is a nice tweak to have if you hate the way non-optimized apps look on your iPhone. As always, installing any tweaks may cause problems with your iDevice, so be cautious and read all the instructions before installing them.
