Juniper has been developed to be the most privacy-focused fertility tracking wearable on the market. Juniper does not have any wi-fi or bluetooth capabilities and user health data is stored locally on the device and is only accessible through indicating LEDs and a single button. The device tracks the wearers fertility window through various Fertility Awareness Methods (FAMs) primarily including wrist skin temperature and cervical discharge (Two Day Method). The algorithm learns and develops custom responses to each individual user to more accurately predict the fertility window. Additionally, the device has been developed to have a long battery life and to be comfortable for prolong wearing. The device was designed as jewelry and has an elegant shape to reflect the feminine nature of the application.
