How does it work?

The app uses a unique algorithm to analyse fluctuations in a woman’s basal body temperature to identify ovulation and predict fertile days. The app is used by women in combination with a basal thermometer and informs a woman on which days of her cycle she is fertile and recommends her to use protection (e.g. a condom) or abstain from sex during these days.
