## About

Femometer helps you follow your cycle and fertility in one calm place 🌸 Log your period, symptoms, basal body temperature, cervical mucus and test results, and it predicts your next period and fertile window, including for irregular cycles. It draws your BBT and LH charts for you, reads LH test strips as low, high or peak, and syncs with Femometer devices from the same maker, which also makes smart rings. There's a pregnancy log for later on too, and a paid subscription is offered through the app stores.
