Ealthiness is a mobile health and fitness companion. It guides users through workouts, tracks runs live, visualizes mood and activity over time, and connects them with coaches — turning everyday movement into measurable progress.
We designed and built the app experience end to end, from the exercise and run-tracking flows to the mood graphs and activity insights that keep people engaged day after day.
