Hello! We are working on a proof of concept android software which is already functional but we are adding some extra features before we release it. Until now the backend was written in java - spring framework and now we are deploying a new version written in javascript. We will release a part of it (if not all) before our ICO (June-July) together with our proof of concept software.
