Basal Body Temperature (BBT) is your temperature when you are fully at rest. It is taken immediately upon awakening before any activity. Unlike traditional thermometers, basal body thermometers can measure with increased accuracy to easily detect your fertile window.
The BBT temps will likely surge right after ovulation, with 0.4°F-1.0°F or more shift.
The Easy@Home EBT-100 Digital Basal Thermometer is sensitive enough to measure subtle changes in body temperature with the high accuracy of ±0.09°F，and only takes about 90 seconds for the reading with proper use. The free Premom app can automatically chart your reading inputs and draw your coverline, a visual tool to help you identify your BBT shift. And with Premom you will have unlimited measurements in the cloud.
Note: Users MUST manually enter temperature in the Premom app with this non-bluetooth enable model.
