How it Works?

Rightyme is an app powered by an algorithm that determines your fertility status based on basal body temperature. Just measure with your Rightyme Device, enter it into the app, and let our algorithm do the work.

How BBT works?

During the menstrual cycle, your basal body temperature (BBT) changes and can be used to detect ovulation and identify your fertile window. It is not necessary to measure your BBT every morning, but a routine of doing it most mornings will help the algorithm understand your cycle.
