FAMnerd is an iPhone app that can be used for both Natural Family Planning (NFP) and the Fertility Awareness Method (FAM).
The main difference between NFP and FAM is that NFP doesn’t allow for the use of barrier methods of birth control (like condoms and diaphragms) during the fertile phase, and FAM does. NFP is generally used by folks who don’t agree with the use of contraception, particularly Catholics. FAM doesn’t have any religious affiliation.
Wherever you choose to stand on barrier methods, FAMnerd will work for you. FAMnerd allows you to record intercourse on your chart, and choose whether it was protected (like with a barrier method), or unprotected. FAMnerd includes charting rules that will work with both FAM and NFP, and allows you to choose the rules that best meet your needs.
Whether you’re trying to get pregnant, really needing to stay not pregnant, or somewhere in between, whether you use FAM or NFP, FAMnerd will make it easy to chart on your iPhone.
