Hi Welcome to this blog.
Flex and iOS 8-8.1.x works together, if you aren't sure what "Flex" is or what it can do, it basically adds a Tweak to your chosen apps or settings inside your iOS device, you can also create your own tweaks, like if you want to activate some functions on an app you can!
The video provided below shows how you can stop ads on a certain app, in this case its "Movie Box 3" as demonstrated they jailbroken Cydia works perfectly with this particular app, it stops the ads!
If you aren't jailbroken and want to jailbreak then please follow this link where you can do the same by following my guides!
Using Flex:
1. Download the necessary apps (Flex, Movie Box 3, or you can try any other apps)
2. Open Flex, then go to "the cloud tab which is the middle one"
3. Select your chosen app
4. Pick tweaks that others made for you to install in your app
5. Go to Patches (left tab) and tick the box and exit the app Flex.
Using Movie Box 3:
1. Open the app and use it, no other configurations and no ads display in your way!
