## Overview

Stardust is a health-tracking app for women, available for iOS and Android. It covers the core ground you would expect — menstrual cycle tracking, ovulation prediction and pregnancy tracking — and layers on a distinctive astronomy angle that syncs your cycle with lunar phases in its Moon Magic feature.

The app is positioned as women-built and data-encrypted, with its own health and data privacy policy, and it stresses that your data is private, period. Its editorial side, The Wormhole, acts as a guide to the menstrual-moon galaxy, giving the product a strong point of view beyond raw numbers.

The website itself is primarily a download and information hub: it links to the App Store and Google Play, explains the App Features, points to Stardust Buzz for community reaction, and includes a shop and FAQ. Subscription management is handled inside the app.

## Pricing & Plans

Stardust is free to download and use on iOS and Android, with optional paid features available through an in-app subscription. Subscription management is handled inside the app.

- **Hormone and body-literacy insights:** See how your hormones shift across the cycle and what each phase means for how you feel.
