Genio is a fitness and nutritional coaching app based on Dr. Paul Arciero’s research. I was a freelance iOS developer on this project; the lead developer was Nick Arciero.
One of the primary challenges was synchronizing the data with the server, as the app works offline and via the GenioFit website. We used Realm to persist data, and built a custom system for synchronizing data with the server when online. The app also includes a food database, part of which is cached offline, and coaching videos that are downloaded and stored as needed for the next day.
