Does the same than a £3 thermometer
This is not an accurate way to check your fertility. I have been doing at the same time my basal temperature with the daysy thermometer and another £3 thermometer I bought in a pharmacy and both give me the same temperature every morning. Plus, daysy views just gives me an approximation of my ovulation time or fertility window as if I was an average person. I do have regular cycles of more than 28 days and less than 31. My fertile period is much earlier than what the app shows (which is an average approximation which any other free application could give you). It didn't even change when I added my cervical fluids which are out of the fertile window the app Daysy Views provides. Honestly not worthy. Just get clear blue ovulation tests and detect your fertility peak. And complete information in any other free app regarding your temperature every morning taken with a normal £3 thermometer, check your cervical fluids and that's all. £299 for a thermometer and an application which does not take into consideration your personal data is not worthy
