🔥 ChallengeDays

Create, track and complete weekly challenges — and see who's winning among friends.

ChallengeDays is an iOS app where users can create their own weekly challenges and track their daily progress. The app features a friends ranking system that shows who's completing the most challenges — turning personal discipline into a social and competitive experience.

Built entirely with UIKit using View Code (no Storyboards, no XIBs) and Core Data for local persistence.
