Is a there a good collection of Idevice apps somewhere that we can take and compile and use for this purpose? I am starting to go down the path of making my own simple versions of popular apps like Twitter or pulling the backend apis of other apps for stores all in an effort to remove as much tracking as I can while still keeping functionality. For example, there is a popular convenience store app that gives discounts on items such as coffee but in addition to the standard tracking, I also discovered code that indicates they are using bluetooth beacons to do in store tracking. Instead I am pulling their api to fetch the deals so I can ditch the app. Would be great if there is an existing collection so I can ditch more official apps more easily.
