What is Tempdrop?

Tempdrop is a smart thermometer that accurately derives body temperature from skin measurements for the purposes of pregnancy, contraception, or health tracking. Tempdrop is uniquely able to arrive at an accurate body temperature thanks to a combination of advanced sensors and sophisticated algorithms. 

Tempdrop uses two temperature sensors and an acceleration sensor that measures three-axis acceleration (x, y, and z) to acquire information on ambient and body temperature.

Tempdrop combines two algorithms, a learning algorithm and our patent-pending Active Temperature-Noise Cancellation (ATNC™)  filtering algorithm to both learn personal sleeping temperature patterns and filter out disturbances to temperature readings like blankets or sleeping positions. 

Tempdrop will learn and precisely pinpoint your personal nightly and monthly temperature patterns. It doesn’t matter if you’re TTA or TTC, postpartum or PCOS, light or heavy sleeper, Tempdrop delivers accurate data that’s tailored to you.
