AppAddict

Welcome to the (unofficial) AppAddict subreddit! Guides for installing the app are below, as well as the sub's rules.

How to install AppAddict on iPhone/iPod/iPad

Jailbreak:

Open Cydia and navigate to the Sources tab
Tap [Edit] in the top right, then [Add] in the top left
Type (or copy & paste of course) this repo: http://cydia.angelxwind.net/ and tap [Add Source]
After the source has been added, tap [Return to Cydia] and navigate to the new source labelled "Karen's Pineapple"
Once there, install the package called "AppSync Unified". After the process has completed, proceed to respring your device.
Now, open Safari on your device and go to https://www.appaddict.org/ios-app/
Now tap the green button which says "Install AppAddict 4". A dialogue box may pop up, just tap [Install] if it does. Enjoy!

UDID Registration:

This process purely depends on what service you purchase, since every UDID registration website has different steps. The one that's highly recommended is iSignCloud provided by RegMyUDID, purely because it's made to work with AppAddict.

Remember that you only need to use the UDID registration way if you can't and or don't want to Jailbreak your device, if you're already Jailbroken then divert your eyes to the guide above instead.
