Where is the source code for the Android Blynk app?

I am looking through the github repo and cannot find the source code for the Android or IOS App that runs on the phone. I can see the source code for the cloud server and the source for the hardware libraries but no client phone app source code. Where can I find it?

Libraries and Server are open-source. Apps are closed, but we are building them based on the community feedback.

I would even be OK with closed source libraries, but it would be really good to be able to drag-drop a solution quickly and then tweak it to our needs in coded.
