To start, we’ve built a stand-alone prototype application we call “Kerplapp” (as in Kerplop for Apps). Using Kerplapp an established user can select applications already installed on their phone that they wish to make available to other users. Using the selected applications Kerplapp builds a simple binary F-Droid repostiory on the user’s device. The local on-device repository is then made available over a WiFi connection to other users on the local area network. Kerplapp will even display a QR code with the information required to add the local Kerplapp repo as a source repository for an F-Droid client running on another device. We hope to eventually merge our work back into the official F-droid Android client, but while we work out the kinks the Kerplapp application operates side-by-side with the F-Droid client app.
