Stardust
A women-built period, ovulation, and pregnancy app that also publishes cycle-and-moon material.
Best forPeriod, ovulation, and pregnancy tracking if you also like a lunar frame.
Who it's for
People who want a women-built cycle app and will treat moon material as lore, not a method.
Stardust's site describes period, hormone, ovulation, and pregnancy tracking and says data is encrypted. It also offers lunar and cycle lore. Moon content is not a medical method. Treat any fertile-window estimate as an estimate.
Pros
Covers period, ovulation, and pregnancy, and the site says data is encrypted.
The presentation is more atmospheric than a clinical chart.
Cons
Moon content is not a medical method.
A paid plan exists. Confirm what works before you pay, and treat any fertile window as an estimate.
