Hi Guys Here is an app I found that has a repository of open source apps
The F-Droid Repository is an easily-installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The server contains the details of multiple versions of each application, and the Android client makes it easy to browse, install them onto your device, and keep track of updates
How to install
Download the apk
install as normal apk
Note the first time you run the app it will take some to build the repository - be patient!
