FormelAppen

FormelAppen is a mobile app that gives Norwegian students fast, offline access to the formulas they actually use — across math, physics and chemistry, from ungdomsskole all the way to university. Instead of flipping through heavy books or scattered PDFs, everything is organised by subject and level so you can find what you need in seconds.

The app is built with React Native and Expo, with Supabase for authentication and secure content delivery, and supports both Stripe and Vipps for payments. It is now live on both the App Store and Google Play.
