The effectiveness of every contraceptive, as well as fertility trackers, is based on the Pearl-Index (PI). This is calculated by how many pregnancies occur in a group of 100 women in the course of one year. For example: if one out of 100 women who use the same method for one year becomes pregnant, the Pearl-Index is 1.0. If two women become pregnant in one year, it is 2.0. This means that the lower the Pearl-Index, the safer the contraceptive.
Important: Daysy is not a “contraceptive app” or “birth control computer.” Due to their certification, popular “contraceptive” apps advertise to be in the same class of medical product as the condom. According to directive 93/42/EWG, medical products that serve as birth control or protection from sexually transmittable diseases, such as the IUD or condom, are automatically assigned to class IIb. However, this classification gives no indication of the efficacy of a method of birth control. The classification only indicates the risk to the user’s health in terms of possible side-effects such as infections, intolerance, adhesions, thrombosis or the possible transmission of HIV. Since an app alone cannot prevent pregnancy or STDs, being named a contraceptive and thus placed in Class IIb is very misleading. Daysy indicates fertile and infertile days with 99.4% accuracy and completely side-effect free. It is the user’s choice to plan or prevent pregnancy on these days.
A few degrees make the difference
In addition, Daysy uses a very sensitive sensor to measure the basal temperature. Its unique feature is that it waits for the mean temperature value, which can take between 30 and 60 seconds. The sensor warms up before it records your basal body temperature in order to receive a reliable result.
Daysy waits until the final temperature value has stabilized to complete the reading. If the temperature drops during the measurement (for example, due to cold air that gets into the mouth through breathing), the sensor waits for it to rise again and stabilize. This method ensures that the measurement is as precise as possible.
