Hey Product Hunt,
I'm Kartik, an iOS developer from India. Chalk & Sum is my second App Store app, after WaveQuest (it won the Swift Student Challenge this year).
I wanted a math puzzle that feels like playing with chalk on a board, not like taking a test. So there are no timers and no lives. You swap a few tiles, add + − × ÷, and make the number in chalk. Every chapter you finish adds a doodle to your board.
It's all SwiftUI, even the chalk texture is drawn in code.
Which level made you stop and think? Which level made you stop and think? And if you hit any bugs or have suggestions, please tell me. I'll read every reply.
Yes, you can doodle in this class!
