Zion wallet (of HTC Exodus1 Blockchain Phone) has a nice UI


The reasons I think it's nice:

  • The metallic feeling of the passcode pad makes me feel secure. It's apparently borrowed from Brushed metal
  • The orange "Send" Button together with the orange transaction preview made it super clear what I am confirming and where should I look for mistakes. Note that Orange here stands for BTC. Eth, for example, has a different colour

However: I don't see the USD value on this screen, which might be just fine because I saw the USD value on the previous screen.

What does "Cancel" button suppose to do?

This is a transaction confirmation screen so cancel means the user don't confirm the transaction and is the MS-Windows equivalent of "back" button in a proper mobile design.
