Three weeks
changed her read.

This is about Maya. She logged her mood for twenty-one days. What she learned surprised her. And quietly, this is what MoodGenius does.

Week 01

The rough week.

Maya had been feeling off for a month. Not depressed, not exactly. Just fogged. She'd journaled, cut caffeine, tried a meditation app. Nothing told her why.

"I knew I felt bad. I didn't know what was making it bad."

Week 02

The pattern appears.

After fourteen entries, MoodGenius wrote her a sentence. It wasn't profound. It was specific.

Week 03

The change.

Maya moved her bedtime. Not every night. Four of seven. The app tracked everything else without her thinking about it. The next Sunday's read surprised her.

"I didn't have to believe it. I could see it."

What she took away

"I still have rough days.
I'm not confused by them anymore."

MoodGenius didn't fix Maya's mood. It turned her mood from weather, something that happens to you, into weather with a forecast. The difference is everything.

The science

Mood isn't mysterious.
It's measurable.

Four decades of research shows mood follows sleep, movement, sunlight, and reflection in ways that are stubbornly consistent. MoodGenius surfaces your personal version of that pattern.

A note from the founder
"Honestly? I built MoodGenius because I couldn't get out of bed.

I was going through the hardest stretch of my life and grasping at anything that might help. Tracking my sleep, checking my HRV, pacing around at 2am asking ChatGPT how to feel better. Just trying to find one small thing to make tomorrow possible.

The data was all there. It just wasn't telling me anything I could actually use.

So I built what I needed. Something that reads your life and gives you back the one honest sentence you already half-knew.

This is the app that helped me survive. I hope it helps you too."

Questions

The short answers.

No. MoodGenius works with self-logged mood alone. But a Watch (or Health app data) makes the insights dramatically richer, because we can correlate mood with sleep, activity, and heart-rate variability.
Your mood entries and journal notes sync to your account on our servers, encrypted in transit and at rest. Your Apple HealthKit data — sleep, HRV, steps — stays on your device; we read it locally to generate insights and never store it on our servers. Delete your account any time and all associated data is permanently removed within 30 days. Full detail in the Privacy Policy.
After about 14 entries you'll see your first pattern. Three weeks is when the app starts sounding uncannily right.
No. MoodGenius is a tool for self-understanding, not treatment. If you're struggling, please talk to a professional, and consider bringing MoodGenius data with you.
