75 Challenge: A Fitness & Mental Strength App

75 Challenge is an iOS app I developed for one of my Upwork clients. It allows users to track their habits, workouts, and water intake.

The app was fully developed by me from a Figma design file.

Technologies: - UIKit (front end) - Core Animation (animating views & transitions) - Realm (storing users' data locally) - StoreKit (in-app purchases)
