  FitFix is an app that wants to help people who are going on a weight loss diet, by helping them chunk their weight loss goal, set their daily calorie goal, and evaluate their progress to minimize the chance of the yo-yo effect in dieting. This is inspired by emotional eating as our initial topic, but after validating the problem through research and interview, it is actually not a problem for our user. So after we brainstormed together, we found that emotional eating is one of the causes of the yo-yo diet which leads to the creation of FitFix. FitFix is available on the App Store.- Brainstorming and conducting research to validate the problem with my teammates.- Collaborating with Project Manager, UI/UX Designer, and other iOS Developers to build this app.- Creating and testing logic to calculate calories, BMI, and more that are connected to diet.- Creating the logic for fetching step count data from the Health app using HealthKit.- Creating views.- Implementing the new Swift Charts framework in Assessment Result View.- Saving users’ diet data into CoreData. Show less trackee is an app built for the iOS platform to track and save our learning resources in the app. I built this because usually we don't document or save our resources, and when we want to access that resource again we forget the name of the web or books. trackee also has a Pomodoro timer for our learning for about 25 minutes, so our learning could be tracked properly.- Brainstorming ideas to be translated into an app.- Designing the app’s UI.- Creating the view.- Code the business logic. Show less MoviePin is an app to help users find movie set locations, so they can plan their itinerary for traveling more easily. This app is inspired by our love for movies and places-places that look beautiful and iconic in the movie, but sometimes we don’t know where the place is in the real world.- Brainstorming and conducting research to validate the problem with my teammates.- Collaborating with Project Manager, UI/UX Designer, and other iOS Developers to build this app.- Creating the Bookmark View and movie location bookmark logic.
