Because her Tappy app got like 100+ downloads on Google Play Store, and seems like no one use it at all (I tried it and there was like 1 inactive chat room for the whole Ho Chi Minh city area).

If someone pay 7 figure for an app no one use, the whole app developer community are all millionaires by now.

Is this the Tappy app ? --- http://tappy.co

So from what I see , what it does is help the user make games from themes.

I signed up for access, still waiting for confirmation

Looks like a pretty cool concept ... a lot of users like to play mobile games while waiting for their friends or travelling ... I mean, its not on the level of Starcraft or Diablo , but its a pretty neat concept ...

No it's not.

This is Tappy: https://play.google.com/store/apps/details?id=com.tappy.app&... - a location based chat app.

The tappy.co is redirected to weeby.co, which is the company she claimed to have bought Tappy for 7-figure sum.

Cool ... how is this different as a social networking working compared to FaceBook ?
