☽ Ovulate — Moon Cycle Tracker

Basal Body Temperature

Your temperature rises ~0.2 °C after ovulation and stays high until your next period. A reading each morning (or your Oura ring's nightly temperature) lets the app confirm when you actually ovulated — and after a few cycles, predict your next ovulation from your own body instead of the standard formula.
