Reelfit is a mobile fitness app where a short onboarding quiz about goals, level, and available time builds a personal training plan, then guides the user through video workouts while tracking calories, steps, meals, and body progress. As the UX/UI designer, I designed the full flow from onboarding and the home dashboard through workout programs, the nutrition tracker, progress statistics, and the subscription paywall, in a dark style with lime-green accents that keeps the app energetic and easy to read during a workout.
