The iOS-Frontend is UIKit and RxSwift. The backend is pretty lean — TypeScript, Firestore with the beginnings of PostgreSQL (with Prisma!). The recommender piece for the daily tips is Python. We also use cloud functions to run async updates (e.g. for daily updates and migrations).

As for the future, we're exploring Flutter and a few other options to provide different experiences.
