Fitness tracker for watch

Mobile iOS developer

At the start of the project, I worked on data analysis, documentation, flow architecture and project plan. I provided the solutions which didn't violate Apple policy. The functionality was tracking the pulse, calories burned, training time, tracking the athlete’s state (critical pulse, calm pulse, rest, lack of activity). The challenging parts were watches, animations, management of large volumes of data and business logic, working with a pulse.
