The Daysy fertility tracker recognizes, analyzes, and accurately displays a woman’s unique menstrual cycle.

This technologically supported basal body
temperature (BBT) method is one of the most reliable fertility-tracking methods in the world. Daysy is a lifestyle-fertility tracker that supports couples in their decision-making process to achieve their family planning goals.

To identify fertile and infertile days, the user measures her basal temperature in the morning with the integrated, highly sensitive thermometer. With the aid of the proven and reliable algorithm, Daysy calculates the fertility status and displays it via the integrated LED.

The optional combination with the DaysyDay app for smartphones provides deeper insight and higher user engagement.

Daysy tracks your cycle for you

There are only a handful of days each cycle that you are fertile. The process of tracking when those days occur each cycle is called fertility awareness. The Daysy fertility tracking computer uses the Fertility Tracker Method (FTM) to calculate your fertile days and predict your ovulation. This means, Daysy takes your basal body temperature and menstruation data, and calculates when you are fertile and when you are not.

Daysy draws on the science of different models of fertility awareness to provide highly accurate calculations of your fertility status each day – fertile or not fertile. The self-learning algorithm does all of the necessary calculation work for you to come to these conclusions. The intuitive nature of the Daysy fertility tracker device itself reduces the potential for any user errors and mistakes.

Daysy combines

• A precise temperature sensor that gets the most accurate data reading
• A unique, intelligent algorithm based on a database of 5 million menstrual cycles
• An intuitively designed tracker that eliminates the potential for user error

Easy handling and use

1. Measure Temperature
2. Enter Menstruation
3. See Fertility Status (3 colours)

With these 3 colours you can keep track of your cycle and fertility status:

• If Daysy shows you a red light, you are fertile / possibly fertile.
• If Daysy shows you a green light, you are not fertile.
• If Daysy shows you a red flashing light, that is your predicted day of ovulation.
• Yellow days indicate cycle fluctuations. They can also mean that Daysy is still in the learning phase and should be considered potentially fertile.
