Your cycle calendar shows past periods, estimated next dates and the phase you're in, so it's easier to plan your week, a trip or a night out. Over time your history shows your own patterns, and it's all in one place if you want to bring it to a doctor's appointment.

They get simple support ideas, and you stay in control of what's shared. More than a cycle tracker Your private, encrypted conversation is a home for the everyday: planning a weekend away, adding to the shopping list, sending a voice note or a photo only the two of you would find funny. Private by design App lock and discreet notifications keep your cycle to yourself, even when someone glances at your phone. Comfi Plus Core tracking and pairing work without an account. Comfi Plus adds the AI cycle and supporter assistant through an optional monthly or annual subscription. Predictions are estimates, not medical advice, diagnosis, contraception, birth control or emergency monitoring. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
