TAPP is a mobile app to help take care of the bill when going out to the bars. Users can add their debit or credit card to the app and open and close tabs without having to worry about carrying around cash. When you're done drinking, you just pay through the app. When you're out with friends, you can also use TAPP to split the bill.
We have been the developer on this project since it's inception in 2015, helping the app transform from early demos to a fully functional app with currently over 40 bars participating.
