How to use a Basal  thermometer with Natural Cycles

Your subscription also includes a basal body thermometer, this measures body temperature to 2 decimal places - this is more sensitive than a regular fever thermometer as it detects shifts in temperature that happen during the menstrual cycle. Measure in the morning as soon as you wake up. Input the temperature reading into the app and the algorithm will tell you today’s fertility status i.e. Green Day (not fertile) and Red Day (fertile, you need to use protection). It doesn’t matter if you can’t measure every single day of your cycle, the algorithm can still get to know you if you can measure most of the time. If you’re a snoozer, don’t worry the basal thermometer stores your last temperature so you can measure and input data later.
