Intervals app

I'm a founder of the project. Originally, it was started as a pet project, since I didn't find any good app for HIIT workouts, so I've decided to develop it by myself. The project became profitable at the very beginning with 4.7 overall rating and pretty great perfomance metrics from development standpoint. The project became an isolated sandbox, which allowed me to try new approaches, technologies and tech stack in real life project.
