About

Comfi

Read full description

A period tracker to understand yourself and help your partner understand you. Comfi helps you get to know your cycle and make sense of how you feel throughout the month. As you track your periods, symptoms, moods, and energy, you can look back at your history, notice your own patterns, and build a better understanding of your body over time. Your calendar brings past periods and expected dates together, helping you see where you are in your cycle and what’s coming next as you plan your week, a holiday, or something you’re looking forward to. The details you record stay together, so it’s easier to remember how you felt last month, follow changes across your cycles, or bring your history to a medical appointment. You can also bring your partner closer to your experience. Sharing how you feel gives them a fuller picture of what you’re going through and gives you an easier way to express what you need. That understanding can become part of how you look after each other, through changes in your cycle and everything else happening in your lives. Comfi gives that connection a place to grow alongside your everyday conversations and plans. You might be organizing a trip together, adding something to your shared shopping list, or sending a voice note because you miss each other. Your private, encrypted conversation gives those moments a home, from the things you want to talk through to the photos that only the two of you would find funny. When life gets busy or takes you to different places, a message between work and dinner, a small task taken care of, or a look at where your partner is on their journey home can help you stay in touch. Those little moments sit alongside a clearer understanding of your own cycle, making Comfi part of how you care for yourself and share your life with someone you love. 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, or emergency monitoring. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
