Main highlights

The basal thermometer is a must-have for easily detecting your fertile window and tracking your ovulation day. By entering your basal body temperature manually, the Premom app can automatically chart your reading inputs and draw your BBT shift digitally. Whether you are trying to conceive(TTC), avoid pregnancy naturally, or just want to know your body better, the digital basal thermometer does it all with ease.
Soft Beep Alarm: The basal body thermometer for ovulation tracking has a gentle confirmation beep, when testing is complete. No timer needed. No need to worry about waking up your sleeping partner beside you either. Turn the smart oral basal thermometer off when finished, note that pressing the ON/OFF button down for 2 seconds will switch the measurement unit between Fahrenheit and Celsius.
Quick and accurate measurement: The BBT thermometer for ovulation(1/100 Degree) has high accuracy at ±0.05℃/±0.10℉. The fast basal body thermometer only takes about 60 seconds for the result to appear. Take immediately upon awakening or before any activity for the most precision. Easily recall your last measured temperature in memory.
Flexible and Waterproof: The fertility tracker thermometer tip is flexible and waterproof. Easy to clean by using alcohol or a damp cloth. Note: When "℉" or "℃" starts flashing with Lo on display, the fertility thermometer is then ready for use. This does not mean the battery low.
Customer Service: Experienced customer service agents are available for any questions you may have. We are so confident that you will love the oral basal body thermometer.
