This is an alternative F-Droid client which is based on the older UI of the official client (pre 1.0).
While the new client UI looks pretty, it's sometimes a bit clunky.
Lots of information that was provided clearly in the old UI is now not available or hidden behind more taps now.
F-Droid Classic brings features of the modern 1.x version of F-Droid to the classic UI, this includes:
* Index-v1 support
* Inline changelog entries
* Localized metadata
* Screenshots
* Donation links
Upcoming features:
* Better mirror support
It doesn't support the following features and probably never will
* Swap
* Index-v0 (old xml based index) support
* Support for Android < 4.4
Note: If you want beta updates you can enable the F-Droid Classic repo in the repo management screen. Releases will also usually be available there a few days before they make it into the main F-Droid repository.
