I actually liked the last iteration of the wallet, clean and simple to understand. I'm not sure anyone would of struggled to see there was a BTC wallet as well if they swipe but hey whatever.
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.

I deleted my post after using the current app again...I think it is much better in design than the new apps. The current app is VERY clean. I think there should be access to the transactions but they should stay hidden. I'll repeat my suggestions for functionality tweaks.
Suggestions:*From the chat screen you should have buttons that paste your gemz or btc addy in the txt box. There would be no need to go copy the addy and paste it in the txt box....seems like it would be more seamless and have less room for error.
*On the chat screen, when you copy an addy in the message box, there should be a pop up option to "send coins to this addy?"
*Both BTC addys and GEMZ addys start with a "1" for single signature addy. To help avoid confusion as to weather an addy is a BTC or GEMZ addy, maybe in the app you display "GEMZ1DvRZcgfVynB8G4o1wJK3mX9uWztoQBb2E" and have the wallet disregard the "GEMZ" at the beginning of the addy for all the inner workings.
*Start your own shapeshift like service and your company could profit from the exchange fee and spread. Due to the ease of exchanging in app you could charge a higher exchange fee than the current exchanges (.5% ish).
