Say Goodbye to clunky paper charts and hello to the Marquette NFP™ Pro charting app! Unlike predictive apps, Marquette NFP™ Pro app uses the research-backed algorithm developed by The Boland Institute for Natural Family Planning (INFP) to give you clear insights into your fertility. With a 98% accuracy rate, Marquette Method offers couples a natural, reliable way to joyfully embrace their fertility. Marquette NFP™ Pro makes charting using the method simple. With clear, easy to interpret charts, couples are able to achieve or avoid pregnancy with confidence. PLEASE NOTE: We recommend learning the Marquette Method from a Marquette Method Certified Professional (MMCP) before relying on the app for Natural Family Planning decisions. Key Features: ● NON-PREDICTIVE CHARTING. Instead of predicting fertile windows and menses, the app uses the proven Marquette Algorithm to determine periods of fertility based on daily data input. ● EASY-TO-READ CHARTS Clear charts allow users to better view their cycle overview and share it with an instructor to get help if needed. ● CUSTOMIZABLE BIOMARKER SETTINGS. Couples can choose which biomarkers to track! Allowing for users to add additional biomarkers such as temp and LH tests to their charts. ● COMMUNICATE WITH YOUR INSTRUCTOR. Clear easy to read charts make it easy for the couple to see and understand their fertility. Easy export options allow couples to easily share their chart with their MMCP for personalized conversation and 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 Boland Institute for Natural Family Planning. The Marquette NFP™ Pro app is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Subscription Required.
