If you were looking for a Google Play Store alternative, consider F-Droid. It is an app store featuring open-source software that comes with source code, allowing developers to customise. The apps aren't as many as in Google play, but the selection is excellent nonetheless.
Multiple version downloads
F-Droid asks for no user account for you to download apps, which means that it won't store your downloads. All applications come with free licenses, as well as the source code. It also enables its users to download several versions of a piece of software, helping them avoid incompatible apps.
Doesn’t have search categories
This programme features a well-organised interface, showing you the list of installed and available apps. Browse through the selection or find something specific using the integrated search tool.
There are also many configuration options to customise your search. The only downside in the design is the lack of defined categories.
Transmit apps wirelessly
If you want to expand the list of apps available to you or play around with the standard version, F-Droid is there for you. Once you alter them, you may send them to other devices either through Android Beam or Bluetooth.
A Fantastic Alternative
F-Droid features an excellent app selection free of charge, in many versions. With no login requirement and the streamlined UI, there aren't many downsides to the app. What it does lack is the versatility and detailed descriptions of most other app stores.
