WAKARUMADE - iOS Math Learning App
A comprehension-first math learning app now available on iOS.

Started as a solo project for Hack This Fall and evolved through rapid iteration with real user feedback. The app adjusts difficulty in real time based on student performance.
Available on the App Store and on the landing page. Built for Hack This Fall.
