Unsure how this could be a 'fake' application when the source code is available and I have already gone through it. I made an open source steem app also, the source code of that one is on github too. Is that also fake?
For the foreseeable future there will be no Official steem app, Steemy is not official and neither is this but it certainly is a step in the right direction when the devs of steemit have said they have too much to do on other tasks to focus on a mobile app.
