Split app wireframes - Manage your group expenses

Hey guys,

This is a shot of a new project i'm working on!
I'm currently in New York for 4 months with friends and it was difficult for us to find an efficient application to manage our common expenses. That's how was born the "Split" project : a simple and fun application to manage common expenses with friends.
This shot is the first part of wireframes.

I will upload some others shot soon, stay tuned!
