SwiftTally was designed for one thing and one thing only; to allow the fast entry of a totaling list. It was originally created by me for my old Pocket PC in order to keep track of my spending while grocery shopping. I have completely recreated it for the iPhone. It has both allowed me to not spend over what I have planned to spend, and has helped me catch miss-priced items on many occasions, since I knew about what the total should be before getting to the register. This is an updated version created to teach myself React Native using Expo.
