Our Wallet was a side project result of our very wandering feet. My friends and I like to travel a lot and we always had to set a time to calculate our expenses, so we decided to create an app for that. The app is easy to use, just add your group expenses, and you can check who owes who and how much at anytime.
I designed and developed this with my friends Jervis and Nico. We published this in Google Play a couple of years ago, but we haven't updated it since then. We still use this app though, it's very handy. :)
