A nonprofit fertility-charting app for periods, cervical fluid, temperature, and hormone tests.

Best forCharting your own fertility signs, without an app declaring an all-clear.

Who it's for
People learning to record cervical fluid, temperature, and hormone tests who want a nonprofit app.

Read Your Body's site describes a privacy-focused menstrual app from a female-led nonprofit. You chart your own signs rather than receiving a contraceptive clearance. The publisher links to the App Store and Google Play. Charting takes practice, and this app is not a certified birth-control device.

Pros

  • Female-led nonprofit, with a privacy-focused pitch and apps on iOS and Android.
  • You keep the chart. The app does not hand you a contraceptive clearance.

Cons

  • A free trial is followed by a monthly or annual payment.
  • Charting takes practice, and this is not a certified birth-control device.
