Personally, it reminds me of those 'get paid for doing surveys!' apps...it's kind of cluttered.
What looks cluttered? Would like to hear your feedback.
When I say cluttered, I mean that there is a lot of real estate taken up by things that are intended to re-direct user attention and function. Get a few gemz for spreading the word on social media and then redeem your gemz - it's kind of what many 'paid for survey apps' function as. Which is fine, but if the intent is to work as a social media/chat client that enables tipping then being inundated with sponsored/sponseree content is, in my opinion, clutter.
It might work as intended but a fair point for me to make is that I am somewhat biased from the perspective of a 'centralized but decentralized' client...that and I see no point for stickers to exist...; )
Edit - Intended Bitbillions rather than bitcoin billionaire and only aspects of that website. Omitted the reference entirely.
