As women, our bodies are constantly changing. We flow through distinct phases, experiencing shifting waves of energy, focus, and emotion. I created Flo to replace rigid traditional tracking with a playful, adaptive user experience that transforms data into an empathetic journey. By connecting the dots between our hormones, mood, and energy, the app serves as a supportive companion—giving us the clarity to decode our unique biological rhythms and live in harmony with our bodies, rather than fighting against them.

This app is WIP and created using both Codex & Claude. Checkout the demo: https://yuinchien.com/flo/.

To embrace all our complexities, I designed a dynamic, adaptive system that visually mirrors your daily mood prediction. The typography and colors shift with your biological state: calming blue for balance, optimistic green for elevated moods, gentle coral for low-energy phases, and vibrant magenta for anxious shifts. This translates raw data into an empathetic visual language, creating an immediate, responsive mirror for your day at a single glance.

the "Cycle insights" dashboard serves as the intellectual engine of the application. Driven by data, Flo synthetically evaluates your logged history to generate a comprehensive, personalized overview of your unique rhythms—such as mapping out your luteal phase, predicting your next period window, and tracing your mood patterns.
