Overview
For our third project in the Iron Hack UX/UI Design Bootcamp, we had to create a dashboard for a wellness app to explore the intricacies of data visualization.
We chose to focus on the correlation between the menstrual cycle and mood swings.
Scope
We had 2 weeks for this project to do user research, competitive analysis, product development and prototyping.
We were expected to deliver the dashboard screen alongside one user flow that illustrated how to input and use the data.

My role
Although we were all equally involved in the design thinking process and product development, I took the lead in the design implementation.
Understanding the relation between Mood and Period
Designing a mood and period tracking app began with a simple but crucial observation: not all bodies follow the same biological rhythm.
Male bodies operate on a predictable 24-hour testosterone cycle.
Female bodies move through a 28–29-day pattern of shifting oestrogen and progesterone levels.
Yet most products, systems, and even definitions of normal are built around the male cycle, leaving many people with hormonal cycles underserved or misunderstood.
We wanted to challenge that by focusing on how hormonal changes influence mood and well-being and creating a tool that feels supportive and compassionate.
Understanding these fluctuations helps users navigate their monthly rhythm with more clarity and kindness.
User research
We surveyed users better to understand their experiences with mood during their menstrual cycle.
We learned that many people before their period are overall
More emotionally sensitive
Experiencing mood swings, sadness, and irritability.
Interestingly, even with different levels of consistency and regularity, 88% of surveyed users rely on apps to track their menstrual cycle.
Users are generally curious about the link between their menstrual cycle and mood and want to learn more.
Periods tracking apps focus on reproductive health and pregnancy.
Period tracking apps rely on articles as main source of recommendations.
Manual data input, both in period and mood tracking, prevents continuity.
None of the competitors offer daily personalized tips.
Daylio only focuses on mood and journaling.
There isn’t any app that combines mood and period tracking at the same level.
