TATA a crypto social network claiming to have 11 million users

After TATATU.com, now I discovered TATA, a Chinese app claiming to have 11 million users! (I'm not so sure about that).

Thought of trying the app just for fun, but it's asking for my phone number and I don't feel comfortable giving it to a Chinese company that I know nothing about. Anyway, in case you want to try it, here are the website, a "review" and their Android app.
