The kids made their first app: Colorful Calculator

They worked on this together for a week and voila, here is their first real app, a calculator with beautiful color design, which they called “Colorful Calculator”. They also came up with the whole video setup on their own, testing and adjusting it for hours.

I teamed up with Abhay to make a calculator app! This is my first-ever calculator app, my first-ever real parser, and the first time we actually wrote about equal parts of the code! Abhay wrote the actual app, and I wrote the parser (which is basically how it calculates things). The app: https://snack.expo.dev/@abhayk/calculator

Run on mobile: download the “Expo Go” app, open the link on a computer and scan the QR code that appears

Run on the web: open the link and switch to the “Web” tab
