Tempdrop is the first wearable BBT sensor that learns how each woman's minute daily variations correlate with her specific hormonal fluctuations throughout the ovulatory cycle. Consider it your very own intelligent, user-specific thermometer.

The accuracy of Tempdrop's data allows you to identify recurring temperature patterns up to 5 days before ovulation whether you're trying to conceive, trying to avoid, or just enjoy tracking your cycles.

Powered by our patented Active Temperature Noise Cancellation (ATNC) technology, Tempdrop's accuracy is achieved using multiple sensors and an algorithm developed by top engineers and doctors.

Tempdrop learns your specific nightly and monthly temperature patterns to achieve user-tailored accuracy whether you're TTA or TTA, postpartum or PCOS, and whether you sleep through the night or wake up throughout.
