Pinpointing the fertile days is a vital to increasing your chances of conceiving. OvaCue Mobile offers a convenient and accurate method for predicting the fertile days of your cycle, offering up to 7 days advance notice of ovulation. The first fertility monitor to connect to your smart phone or iPad, OvaCue Mobile is easy to use, over 98% accurate (according to NIH-funded studies), and requires no messy urine testing. OvaCue Mobile consists of an adapter, an oral sensor, and a vaginal sensor. The adapter plugs directly into your smart phone or iPad*, and the oral and vaginal sensors plug into the adapter. OvaCue Mobile works in conjunction with the OvaGraph mobile app, a FREE download from your App Store, which stores all of your menstrual cycle information and displays this information in customizable graphs and calendars. While OvaCue Mobile is new, the technology behind this monitor has been around for decades. OvaCue Mobile uses patented Electrolyte Method to measure and track changes in the electrolyte concentration of the saliva and cervical mucus. By detecting changes in electrolyte levels, which reflect changes in hormone levels, OvaCue Mobile can predict when you will ovulate and then pinpoint ovulation. To use OvaCue Mobile, you take readings each day with the oral sensor starting on Cycle Day 2 of your menstrual cycle (the second day of your menstrual period) and daily readings with the vaginal sensor starting as soon as menstruation has ended. OvaCue Mobile will track and interpret these readings to provide a prediction of your most fertile days of the cycle. *OvaCue Mobile is compatible with most iOS devices running iOS 7 or greater, including: iPhone 7, iPhone 7 Plus, iPhone 6, iPhone 6 Plus, iPhone 5, iPhone 5C, iPhone 5S, iPhone 4S, iPad 2, iPad 3rd Gen, iPad 4th Gen, iPad Air, iPad Air 2, iPad Mini 1, 2, and 3, and iPod Touch 5th Gen.
