i read it on the whitepaper that Datum will realease an early alpha before token launch.
So i think in the next week will be done.
But this is still not released? You said about launched alpha... I seen only images of app in whitepaper..
According to Theo Valich-Head of Growth, Alpha version has been released. Here link:
