Fitness & Wellness App
A holistic health and fitness application that combines workout tracking, nutrition planning, and behavioral insights powered by wearable data.
The Challenge
A fitness brand wanted to launch a mobile app to compete with major players:
- Crowded market - Standing out among thousands of fitness apps
- Engagement drop-off - Most users quit after 2 weeks
- Data silos - Wearables not talking to nutrition trackers
- Generic content - One-size-fits-all workout plans
They needed an app that users would actually stick with.
