Period Tracker - Ruby

Meet Ruby – your simple, smart, and free period tracker.

Whether you want to track your menstrual cycle, get accurate ovulation predictions, or simply have a clue about your period, Ruby makes it easy to understand your body. Think of it as having Aunt Flo, Aunt Ruby, and your own personal cycle tracker all in one app.

With Ruby, you can:
- Log your period, flow, and symptoms with just a tap
- Use our ovulation tracker to know your most fertile days
- Predict cycles with a free period tracker that adapts to you
- Track emotions, energy, stress, and notes in one place
- Get gentle reminders for upcoming periods, ovulation, and fertile windows

Why choose Ruby?

- Free forever – If you join before Sep 15th, 2025.
- Simple & private – Easy to use, built with privacy in mind.
- Your cycle, your way – From teens starting their first period, to women tracking fertility, pregnancy, or perimenopause.
- More than a calendar – Ruby helps you spot patterns, manage PMS, and make your cycle feel less of a mystery.

How Ruby Stands Out
- Have a lively cycle every month with personalized insights.
- Finally, an app that helps you truly have a clue about your period.
- Forget “my cycle” being hard to remember—Ruby keeps it all logged for you.

It's just a clean free period app experience.
