Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
A cycle app that actually helps day to day. Private. Honest. Built for couples (any gender).
WHY LUNA
Not just another app that gives you a date.
Luna helps you understand your own patterns, without pretending to know everything.
And it’s built to respect what should stay private.
WHAT LUNA DOES WELL
- Track your cycle, symptoms, energy, and mood
- Calendar with phases and uncertainty ranges, not fake precision
- Daily card: what may be changing today, and what could help
- AI chat based on YOUR cycle, not generic averages
- Respectful partner mode, notes and intimacy are never shared
- Useful notifications, never guilt-driven
DESIGNED FOR COUPLES
Luna’s partner mode gives your partner the right level of context.
Not your notes. Not your journal. Not your temperature.
Just: “where you are in your cycle, and how to show up for you.”
It works for straight couples, lesbian couples, and any relationship where two people want to support each other without surveillance.
PRIVATE BY DESIGN
- Hosted in Frankfurt, EU
- No ads

WHAT LUNA IS NOT
- Not birth control. Luna is not designed to prevent pregnancy.
- Not medical advice. It’s education and guidance, not diagnosis.
- Not a crystal ball. We show ranges, not invented certainty.
