2. Aptoid
Aptoide client is an open source Android application that
allows one to install software. The installed software comes from multiple
sources called "repositories". Each repository has multiple
applications and are distributed over different locations. Repositories contain
the latest applications allowing you to control and be notified of updates.

3. F-Droid
The F-Droid Repository is an easily installable catalogue
of free and open source apps for Android. With F-Droid, it is easy to browse
and install apps on your device, and keep track of updates. You can also browse
the repository with a web browser, and download the app directly from there, if
you cannot or do not want to run the F-Droid client on your device.
All applications in the default repository must be Free
and Open Source software – for example, released under a GPL or Apache license.
Every effort is made to verify that this is actually the case, both by visual
inspection of the source, and by building the application from the published
source.
Software that reports user activity without permission
(e.g. via Google Analytics) or tracks user behavior (e.g. most advertising
platforms) is specifically excluded from F-Droid’s own repository, as is
software with the primary purpose of interacting with a non-Free network
service. You are, of course, free to set up your own repository for this kind
of software – the server source is available, and the client will allow
addition or removal of repositories as you see fit.
