Expense splitting app

I've gone an a bunch of trips before where figuring out expenses between a group of friends has been a major hassle, so I decided to build an expense splitting app as an exercise to help me figure out how to make iPhone apps. So far things have been going really well, I hope to have the app submitted to the app store in the next few weeks.

Shoutout to @Treehouse for flattening out the learning curve of Swift and iOS development! Already looking forward to starting my next app... :)
