Did you know that you can tweak apps with no jailbreak using Extensify? Extensify is especially handy if your device is on a version of iOS later than 9.0.2 (that currently cannot be jailbroken). You can install it by visiting the Extensify website with Safari, using the device on which you’d like to install it. After the app is “trusted”, you can browse the store and install what are named “Exos” which is the name given to the extensions that are similar to jailbreak tweaks. The “Exos” will modify “App Store” apps only.
