Say goodbye to clunky paper charts and hello to the Marquette NFP™ Pro charting app! Unlike predictive apps, Marquette NFP™ Pro uses the research-backed Marquette Method algorithm, developed by the Boland Institute for Natural Family Planning (BINFP), to provide clear insights into your fertility. 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. Key Features: • NON-PREDICTIVE CHARTING Rather than predicting fertile windows or menses, the app uses the proven Marquette Method algorithm to determine fertility status based on your daily data. • EASY-TO-READ CHARTS View your cycle in a clear calendar format or a paper chart-style view. Easily follow your cycle and share your chart with an instructor for additional support. • CUSTOMIZABLE BIOMARKER SETTINGS Choose which biomarkers to track and customize your chart with additional observations, including temperature and LH test results. • CONNECT WITH YOUR INSTRUCTOR Easily export and share your charts with your instructor, making it simple to discuss your cycle, ask questions, and receive personalized feedback. “The new app will now make the Marquette Method of NFP easier to access, learn, and use… [It] is a true device to help women monitor their menstrual cycle as a vital sign for health.” – DR. RICHARD FEHRING, Ph.D., RN, FAAN, Professor Emeritus at Marquette University College of Nursing, and a research scientist at the BINFP.
