Is Esteem really a HIVE App?

Hello everyone,

I just want to know that is esteemapp really a HIVE app? Reason to ask here is that I just downloaded the app and it is showing my HIVE contents in it, but the problem is there are allot of options to gain the EST coins which I don't see here @HIVE.blog website. I am unable to understand that why the name differ with real name STEEM instead of ESTEEM?

Sorry for my bad english but I think they are making fool to people as gained EST coins are not usable and don't have any worth.

Please guide me in this regard.
