F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.
Though, last I checked, IzzyOnDroid does warn that they usually only host things not found on F-droid. Once something they host gets included in F-droid it's often removed from IzzyOnDroid without warning.
Droid-ify offers apps from different repositories so you can have Izzyondroid and F-droid at the same time. It also scans for updates and does auto-updates if possible.
Yeah I know about that but what has that to do with IzziOnDroid apps which pulls the apps from GitHub being removed after they've been added to the official Fdroid repo
If an app is added to the official Fdroid repo, it's removed from IzzyOnDroid after a while. Not the case with every app, but this might happen. Now you have to use the Fdroid version
Its not security I'm looking for. If I wanted security I would be running stock with all of the apps from large corporations.
What's good about F-droid is the freedom you get when you use it. All of its apps are libre. You have the ability to tweak them anyway you want and the source code it yours to study, learn, modify and distribute.
