Courbe de température is an Android application developed by Nicolas Guillochon. It falls under the category of Lifestyle and subcategory Health & Fitness. The app is designed to help women determine their ovulation day and increase their chances of conceiving.

The app is easy to use and requires you to take your temperature every morning using the same thermometer and in the same place. The app automatically constructs a graph and calculates the average temperature. The increase in body temperature is then easily visible on the day of ovulation. The period of intercourse that is most conducive to fertilization usually occurs between the three days before and the day following the increase in temperature. The app is free and does not require any personal information.
