About

Momentum Health is a weight loss assistance company that delivers personalized, provider-guided plans and ongoing support. The app is designed to keep clients on track between visits, but it faced challenges with usability and engagement. Partnering closely with Momentum Health’s product team, I led the redesign of the app to enhance the user experience, align with business goals, and position it as an essential part of each client’s journey toward successful outcomes.

The Challenge: Improving Engagement, Nutrition Tracking, and AI Assistance

Despite its potential, the app struggled with three major shortcomings:

  • Low Adoption Rate: Regular usage was limited to 24% of clients. Feedback pointed to a clunky interface and lack of practical value as key barriers.
  • Limited Tracking Capabilities: Clients struggled to log food and exercise due to a complex, unintuitive interface. As a result, only 40% of frequent users tracked their nutrition, even though consistent logging is proven to drive significantly better weight loss and health outcomes.
  • Low Engagement with Nova, the AI Assistant: Despite its potential to support users, only 17% of app users engaged with Nova. Poor visibility and limited capabilites reduced its overall impact.

The goal of the redesign was to address these pain points by creating a more intuitive macronutrient tracking system, increasing visibility and adoption of Nova, and refreshing the UI and visuals to provide a modern and premium aesthetic that aligned with the company’s brand.

Version 1 (pre-redesign)

The Solution: A More Intuitive, Engaging, and Helpful App

The redesign centered on solving three core challenges: making Nova more visible and personalized, transforming clunky health tracking into a seamless AI-powered experience, and elevating the interface to match Momentum Health’s premium brand. Working closely with the team, we prioritized features that directly addressed user pain points while enhancing trust, usability, and long-term engagement.

1. Driving Nova Engagement Through Visibility and Personalization

I improved Nova’s adoption and usefulness by introducing a prominent dashboard widget that encourages clients to start a chat. The widget leverages our AI capabilities to surface personalized, context-aware suggestions, anticipating likely challenges based on patterns from similar clients and guiding users toward meaningful conversations. Inside the Nova screen, I added a history of past interactions, allowing clients to continue evolving conversations as new obstacles arise, reinforcing continuity and sustained engagement.    

2. Reimagining Health Tracking with AI

With clients frustrated by a tracking process that felt clunky, time-consuming, and unhelpful, we saw an opportunity to reimagine the experience through AI and smarter feature design. Together with the team, we introduced several improvements:

  • Daily Journal & Progress Indicators - a clear dashboard view giving users an at-a-glance understanding of their day.
  • Quick Add for Common Meals - reducing repetitive manual entry by making frequent foods instantly accessible.
  • AI-Powered Tracking - enabling users to snap a photo or write a short description, with AI parsing the meal’s nutrition, offering personalized feedback, and logging it automatically.

3. Building Trust Through Modern UI

The previous interface felt dated and inconsistent, which weakened client trust and the experience less intuitive. To address this, I elevated the UI with a cohesive design system, modern typography, and high-quality visuals and icons. These updates not only improved usability but also conveyed a premium, trustworthy brand experience—essential for keeping clients engaged and confident in the app.

Results: Increased Engagement and Habit Formation

The redesign led to significant results:

  • 2.5x increase in adoption rate, up from just 20% previously, making it an essential tool in their weight loss journey.
  • 42% increase in daily nutrition tracking from expanding tracking capabilities and addressing users' pain points.
  • 34% increase in active Nova usage, resulting in measurable improvements in health outcomes through smarter guidance.

This redesign positioned Momentum Health’s app as the core of their customer experience, driving engagement and supporting clients’ progress between provider appointments.
