My big negative of the above wallets apart from looking overly complicated for the sake of it compared to like I said the last one is the Facebook blue used. Maybe its cause I hate FB but I think using FB blue for an app unless its just an option of many is a bad idea.
I do agree that the current wallet is simple and easy to understand. With a few tweaks it would very easy to figure out for a new user. The "receive coins addy" should be accessible from the chat screen.
Suggestions:
Transactions should be hidden unless called for by the user..much cleaner that way.
*Maybe an in app feature box tutorial is in order to lead the new user through the features.
As I'm not alone in my negativity I'll be a bit more blunt. The above wallets look kind of dated in style. They kind of look like the banners on some 90's website or something. Sorry.
To be honest I'm more worried about getting the airdrop started that the apps design. App design is bound to change over time anyway, most important is that it works at the moment.
