Say goodbye to clunky paper charts and hello to the Marquette NFP™ Pro charting app!

With a 98% accuracy rate, the Marquette Method offers couples a natural, reliable way to joyfully embrace their fertility. Marquette NFP™ Pro makes charting with the method simple and accessible. With clear, easy-to-interpret charts, couples can work toward achieving or avoiding pregnancy with confidence. PLEASE NOTE: We recommend learning the Marquette Method from a trained Marquette Method instructor before relying on the app for Natural Family Planning decisions.

RICHARD FEHRING, Ph.D., RN, FAAN, Professor Emeritus at Marquette University College of Nursing, and a research scientist at the BINFP.
