Absolutely—we believe everyone deserves access to high-quality cycle tracking. That’s why our free version isn’t an afterthought—it’s thoughtfully built to be robust, insightful, and genuinely useful. You’ll get accurate cycle predictions, daily insights, symptom tracking, and a little moon magic (yes, we sync with lunar cycles). Premium’s there if you want to go deeper, but the free experience more than holds its own.

Yes!

Stardust Super (our premium subscription) is designed for anyone who wants to go deeper with their cycle—and themselves. Here’s what you unlock:

• Daily Decode: Fresh, cycle-specific content every day across key areas like mind, body, gut health, movement, sex, work, and beauty. Think of it as your daily cosmic-hormonal weather report.
• The Cyclepedia: A searchable library that helps you decode over 150 symptoms, feelings, and conditions—so you can finally understand what your body’s been trying to tell you.
• Signal Sync: Connects the dots between your sleep, energy, and activity patterns and your cycle phases, helping you spot trends and work with your body—not against it.
• Archetype Deep Dives: Get a richer, more personalized breakdown of your period personality—and explore how your archetype interacts with others.

You can also connect with friends or partners to share cycles, dive into the Cyclepedia to decode 150+ symptoms and feelings, and access cycle-specific content across areas like food, sex, work, and more. It’s not just about tracking—it’s about understanding yourself on every level.
