Would you use this chat app?

Im really curious to know if somebody would actually use this app if it existed. The applications concept is quiet simple. It would be as simple as possible. When your friend sends to you a voice message, you press on his face or profile picture and you will hear his message. You would be able to hear it only once or twice, at this point its reminding of snapchat. After that you have heard his voice message, it would disappear. Cool features which could be the apps facelift:

-Connected with Facebook (the profile picture)

-Cool and REALLY simple design

The idea of the apps design is to be as simple as possible, as i mentioned earlier. You would be able to choose your own wallpaper. Now, the thing is that the chats wouldn't be in different message "pockets" like whatsapp and all the other chats. Instead, every chat would appear as small balls with your friends faces. When you receive a voice message, a red "1" would appear above the ball. The only thing you would have to do to send a voice message is to double tap your friends picture. Cool features which could be the apps facelift:

-Its possible to move the balls (profile pictures) anywhere on the wallpaper, just swipe them with your finger

-You can either choose your own profile picture or import from Facebook

Its hard to explain how it would exactly look like, but something like this! So what do you guys think? would this be something interesting or?
