I'm using it and I like the interface, but I agree it could have some security issues, especially since the wallet doesn't lock or require your password, unless you try to do a transaction. That could be a problem, as anyone accessing your phone could see all your balances, simply by pressing the app's icon to open it. They definitely need to add an auto-lock on idle feature and a require a password to open the app. One cool thing though is the QR code scanner, you can send coins to cryptopia wihout typing anything! Perfect for lazy artists like myself lol. Of course, right now, I'm HODLing, there is no way in hell I will be dumping my precious coins at such a low price, when we know this coin is going to the moon!
