Simple Math app

SimpleMath is an app that generates simple math equations for young children to help them solve and learn in a fun way. I've made this app for my 6 year old daughter because I don't have to write or print the equations and I don't need to evaluate them as well, the app does it all. I am very happy I can make my daughter's learning process easier, but this project has also given me a great "toy" to play around and learn / practice SwiftUI & Combine. It is heavily inspired by Paul Hudson's recent SwiftUI Live video, I highly recommend it.

Todo

• [ ] Add light / dark mode support.
• [ ] Customize colors / themes (it is very purple now, my target audience demanded it!).
• [ ] Support landscape layout.
• [ ] Adaptive sessions, use wrong answers from previous sessions, repetition is key!
• [ ] More gamification, with sounds and visual effects, simple achievement system.
• [ ] Helpful hints when tapping on current equation.
• [ ] Flexible equation layout, ex 1 + _ = 3.
• [ ] Whatever my target audience demands!
