NFP Apps & Devices

Many people find it very helpful to use a device to help them track their fertility signs and symptoms. There are also many apps available that can help with tracking and charting. Below are a list of several popular devices and apps.

A few words of caution:

  • We do not recommend using an app or device as a replacement for learning an actual method of NFP.
  • We recommend first learning one of the four major methods, and then using an app or device to supplement and cross-check your practice.
  • The app or device may advise the use of contraception during the fertile phase (if trying to avoid pregnancy), which is not in line with Catholic teaching (see Catholic teaching page).
  • Many of the apps available use a standard cycle length, which may not apply to all women, or may use an algorithm to determine fertility/infertility that may not be personalized to the individual woman.
  • Using an app or device exclusively does not allow you to consult an instructor or doctor if you notice irregularity in your cycle or have a question (with the exception of MyFertilityMD, which has doctors on call – see below).

NFP is very effective in helping couples identify the optimum time for conception. With regard to spacing or limiting pregnancies, NFP is up to 99% successful when couples understand the methods, are motivated, and follow their method’s guidelines.
