Yoona Femtech Personalized Health Platform

A phase-aware mobile companion combining predictive cycle algorithms with an interface that adapts to how the user actually feels.

Client context

Where things stood.

Yoona Femtech, a personal cycle and wellness platform.

Yoona Femtech wanted to redefine personal cycle tracking by moving beyond simple calendars to an empathetic, phase-aware digital health companion. Ascendiz designed and built the mobile experience, combining personalized algorithmic predictions with adaptive user interface themes based on the user's biological phase (Menstrual, Follicular, Ovulation, Luteal).

Solution

System capabilities.

Phase-aware adaptive UI (dynamic themes)

The interface dynamically changes visual theme and tone depending on the user's active cycle phase — soothing tones for Menstrual, fresh energy for Follicular, peak-performance highlights for Ovulation, and a grounding aesthetic with sensitivity tips for Luteal.

Predictive cycle & fertile window algorithms

Calculates personalized cycle length, period duration, and fertile windows based on logged symptoms and historic data, delivering real-time physiological warnings and recommendations as phases change.

Integrated health & e-commerce ecosystem

Direct integration with educational content, personal health tracking tools, and specialized wellness e-commerce products.
