Your body has been trying
to tell you something.

😩

The week before feels like a different person

Mood crashes, fatigue, cravings, anxiety — you've been calling it PMS without understanding why, or how to work with it instead of against it.

📅

You're still surprised by your period

Every month, the same shock. Your cycle should be predictable. The technology exists. You just haven't had it working for you yet.

💔

Your partner doesn't understand — and you're exhausted explaining

You shouldn't need to give a hormones lecture mid-argument. The right information, delivered gently, at the right time, changes everything.

🔒

Your data was sold

Flo paid $56M in settlements for sharing your most intimate health data with Facebook. Bloom stores everything on your device. Always. No exceptions.

Everything you need.
Nothing you don't.

🔮

Cycle prediction that actually learns

Not a population average. Your cycle, your history, your pattern. Prediction accuracy reaches 98% within 3 cycles logged. Period, ovulation, fertile window — to the day.

"I stopped having to explain why I needed space on day 20. He just knew. Bloom sent him a notification. It took 30 seconds to set up and changed everything."

Your animated
health companion.
She gets it.

Luna reflects how your body is actually feeling right now — by phase, by day, by what you've logged. She's not a chart. She's not a number. She breathes, she changes colour, her face shifts with your hormones.

Tap her, and she celebrates with you. Log a streak, and she lights up. She makes health tracking feel like something worth coming back to.
