Questions
Everything you need to know about using these tools.
Yes. All seven tools are completely free to use. No sign-up required, no hidden fees. We built them as entry points to hormonal literacy because every woman deserves to understand her body.
These tools are educational guides, not medical devices. They work best when you track your cycle consistently over a few months. For personalized predictions, the Muuse app uses your individual data to refine accuracy over time.
Absolutely. The Phase Quiz helps you identify where you are right now, regardless of cycle length. The Perimenopause Checker is specifically designed for women whose cycles are shifting or unpredictable.
Your privacy is non-negotiable. These tools don't require login or data collection. Nothing is stored, tracked, or sold. We built Muuse the way we'd want it built for ourselves.
The tools stand alone and work independently. If you download the Muuse app, you can sync your cycle data for daily personalized guidance from Éllia, our AI companion, across all eight life domains.
