Natural Cycles Basal thermometer
This thermometer has changeable units, so it can measure either in Fahrenheit or Celsius.
To get started with Natural Cycles, you need a basal thermometer. This is a regular digital thermometer but with a higher sensitivity than a classic fever thermometer. It measures to a two decimal point, i.e. 98.31° F (36.65°C), which is required in order for the algorithm to find your ovulation.
This thermometer also has a built-in memory feature for your last measurement.
Tip: Our basal thermometer is included when purchasing a Yearly subscription as a new user, so you might not need to buy one.
This thermometer is FDA cleared and manufactured by Veridian Healthcare, LLC.
Usage: Measure your temperature every morning when you wake up and enter the temperature in the Natural Cycles app. A booklet is also included for further instructions of use.
Natural Cycles is a 93% effective, natural method of contraception that is delivered in the form of an app. It uses a smart algorithm that is sensitive to subtle patterns in a woman’s cycle to determine daily fertility, based on basal body temperature.
Natural Cycles is the only app of its kind to be available in Europe and the US for use as a contraceptive
