Why We Built This
Lucas, Founder
The Morning Everything Changed
"One morning, my wife told me she was giving up on mood and cycle tracking apps. She'd tried dozens of them."
The apps looked great but missed the point: they tracked data without connecting the dots. None answered the real question: "Why do I feel this way?"
So we built My Bad Day — the first app that doesn't just track your life, it helps you understand it.

Everything you need to know about My Bad Day
What makes My Bad Day different from other mood trackers?
My Bad Day is the first mood tracking app that connects your mood, sleep quality, and menstrual cycle in one place. Unlike traditional mood trackers that only ask "How do you feel?", we reveal the hidden patterns behind your emotions. Our AI-powered analysis shows you insights like "Your mood drops when you sleep less than 6 hours during your luteal phase" - connections impossible to discover with single-purpose apps.
Can I share my mood data with my partner?
Yes! My Bad Day is the first wellness app that lets you share insights with your partner - completely free, always. Your partner can view your mood patterns, sleep quality, and cycle insights to better understand and support you. This feature helps couples communicate about emotions and anticipate challenging days together.
Does it track menstrual cycles and hormones?
Yes. Our menstrual cycle tracking integrated with mood data helps you understand how hormonal fluctuations influence your emotions, energy levels, and stress tolerance. The app shows you patterns across follicular, ovulatory, and luteal phases, helping you anticipate mood changes and plan accordingly. This cycle-aware analysis is unique to My Bad Day.
How does the AI pattern recognition work?
Our AI-powered mood tracker automatically analyzes correlations between your mood, sleep habits, cycle phases, and relationship interactions. Instead of manually reviewing charts, you receive clear insights like "You've slept poorly for 3 nights - this typically leads to increased anxiety within 2 days." The pattern recognition engine learns your unique triggers and warns you before mood drops occur.
