What Moody doesn’t do
It doesn’t diagnose anything. If something feels wrong, Moody can help you describe it. It can’t tell you what it is.

It doesn’t promise your period will arrive on the day it says. Nothing can. That’s why we call it a forecast.

Common questions about how Moody works
Does it work if my cycle is irregular?
→
Yes, that's the case it was built for. Moody works from what you log rather than from an assumed 28-day month, so an irregular, long, short or unpredictable cycle doesn't break it.

Does it work in perimenopause?
→
Yes. You can log symptoms and patterns without a cycle to anchor them to, and the forecast still runs.

Do I need to log every day?
→
No. More logging makes the forecast more specific to you, but it can run on your cycle history alone. What you log helps Moody highlight patterns in your moods and symptoms over time so you can be more prepared.

Why is the app called Moody?
→
Because moods are part of being human, not a flaw caused by your hormones. We chose the name to reclaim the word: understanding your body is about listening to it, not controlling it.
