The Tempdrop app is designed to complement the Tempdrop device - a personalized user-specific thermometer that captures minute temperature variations throughout the night to pinpoint the basal body temperature. Detected variations in temperature correlate with hormonal fluctuations throughout the menstrual cycle. When used with the Tempdrop device, this app can help users to pinpoint ovulation and effectively track and predict the varying phases of the cycle.

The app and its wearable sensor, in themselves, are not, nor are they intended to be, a fertility monitor, a substitute for contraception, or a birth control method. We recognize the need of some to use the data and information provided to support ongoing health and menstrual cycle tracking, however, it is important to note that this should NOT be used as a substitute for an in-presence qualified professional, medical analysis, advice, guidance, or treatment. We strongly advise seeking a qualified Fertility Awareness instructor or other self-teaching resources to learn a symptothermal method and support your fertility journey. The provided interpretations and prediction guidelines are not suitable for use with irregular cycles. Optimal performance is dependent on correct and consistent use.
