Fertility Chart iPhone Apps

Natural Family Planning Assistance

Fertility chart iPhone apps can be used to assist in Natural Family Planning by charting fertility. Some great fertility chart iPhone apps have been developed to help chart basal body temperature (BBT), predict ovulation and identify fertile days.

Though fertility charts can be helpful resources if you follow the fertility awareness method, please note that these iPhone apps should be used for recreational purposes only. They are intended to gather data and provide approximate fertility predictions and are not meant to be used exclusively in any natural family planning regimen.

The myNFP iPhone app is based on the symptothermal natural family planning method. To effectively use fertility awareness methods for contraception, it is essential that you fully understand how to use these methods. With the myNFP app, you input data about your menstrual cycle, and the app helps to determine your most fertile and infertile days.

  • Allow you the choice to set the app to be used for contraception or to help you conceive.

  • Forecasts the beginning of your next menstrual cycle
  • Data can be entered for future days (a feature not included in some other charting apps).
  • Offers a place to note daily if you had protected or unprotected intercourse, medication use, quality of sleep, alcohol use, illnesses, use of a different thermometer, stress, and other environmental interferences.
  • Easy to read cycle charts.
  • Ensures privacy via a lock-screen (so others can’t access app).
  • You can import/export information about your cycles to and from the online platform of myNFP; send cycle charts as PDFs to your email to store or print.
  • Includes an in-depth manual for use.

The manufacturer of the myNFP App notes that this iPhone app:

  • Supports both Celsius and Fahrenheit temperature scales, but it is optimized for use with the Celsius scale.

  • Temperature values are rounded to the next 0.05°C step, which results in 0.09°F roundings in Fahrenheit.
