CONTEXT
Designing a smarter, more personal way to track your cycle.
I worked Aurelia Vitals, a health-tech startup, to design a mobile app that pairs with their wearable sensor—an earring backing that tracks your vitals overnight. The idea was simple: turn all that data into something people can actually understand and use in their everyday lives.
PROBLEM
Lack of accurate & adaptive cycle tracking in current tools.
Many cycle-tracking apps rely on averages and self-reported data, leaving predictions inaccurate and users feeling unsupported.
GOAL
Turn real-time vitals into meangingful, supportive insights that feel clear and actionable.
Our guiding question was: How might we design an experience uses real-time vitals to make cycle tracking smarter and more supportive? By making data easy to understand, the app helps users feel informed and confident—whether they’re tracking for wellness, fertility, or eventually, birth control.
Onboarding — helping users get started quickly while respecting their privacy
Through our research, we learned that many users are hesitant to start using health tracking apps because of long onboarding flows and concern about data privacy. To address this, we streamlined the onboarding experience give users the flexibility to personalize their setup without sharing sensitive data.
Home — giving users a clear snapshot of their current cycle
We prioritized summaries that highlight the most relevant information at a glance, avoiding medical jargon and clutter.
Calendar — letting users visually track and understand their cycle patterns
Our goal was to reduce visual clutter while clearly distinguishing cycle phases. Additionally, after learning from users that they occasionally reference past cycle data during medical visits, I also proposed a Cycle History view to help users easily compare cycle lengths, period days, and ovulation windows across time.
Track Period / Symptoms — making daily logging fast, flexible, and personalized
Working with my teammates who designed earlier iterations of this screen, I gave feedback based on user preferences for intuitive and minimal input. We also clarified the distinction between predictive inputs (used for AI models) and personal logs.
My Data & Trends — helping users visualize trends and build self-awareness
While the device currently only tracks temperature, we designed the page to display useful trends now and expand easily as new vitals become available. The goal is to help users understand long-term patterns, and position the app as a reliable reflection of their health over time.

→ Iteration is everything!
Each round of feedback—whether from users, our PM, and the client—pushed the design to be more intentional. I learned not to get attached to early ideas and to treat every iteration as a step closer to building something that actually works.
→ Words matter & providing real-time health data does not have to be overwhelming for the user
I learned a lot about what it means to visualize vitals in a way that’s easy to interpret—and also gained a better understanding of how inclusive, thoughtful language can completely shift how supported a user feels. Copy isn’t just way you say it, it’s how you say it!
→ Good UX goes beyond just digital screens
I realized that cycle tracking isn't just about the features and the way things are laid out and how they look—it's about creating a whole experience where people feel seen, supported, and confident about managing their own health!
