Weight Watchers
The new Weight Watchers mobile app represents a major evolution of the WW brand, which is transitioning from a traditional weight-loss tool to a comprehensive, medically supported health platform.
Welcome with purpose
The first few moments with an app set the tone. Bloomly’s original onboarding felt more like a barrier than a welcome. Our challenge: make it simple, warm, and motivating—without sacrificing personalization.
The Challenge
As WW expanded beyond its classic Points program into medical weight loss and personalized care, the existing app experience struggled to:
Clearly communicate complex health and medication journeys
Support users with very different goals, motivations, and levels of engagement
Reflect the new, more premium, and clinical brand direction
Balance guidance and accountability without overwhelming users
My Role & Approach
As a Product Designer, I worked on shaping key parts of the new mobile experience with a strong focus on clarity, personalization, and emotional tone.
Key design priorities included:
Translating the new WW brand system into a cohesive mobile UI
Designing personalized health journeys based on user goals and medical context
Making complex concepts (GLP-1 medication, dosing, side effects, progress tracking) approachable
Supporting long-term engagement through progress visibility, reminders, and gentle nudges
The experience was designed to feel less like a tracker and more like a trusted companion - guiding users step by step while adapting to their pace and needs.
