Most cycle apps are built for her. This one's built for you, to show up better.
See where she is in her cycle
One screen tells you the current cycle day and phase, so you're not guessing whether it's a rough day or a rough week.
Know what usually helps
Every phase comes with a short note on what tends to land well, whether that's planning something or just backing off a bit.
Nothing leaves your phone
There's no account to make and no server holding her dates. The app keeps everything in local storage on your device.
A menstrual cycle runs through four phases, and each one asks something different of you.
Her period. Comfort and patience go a long way here, and big asks usually don't.

Usually the most social, most connected days of the month. Worth planning something.
The wind-down before her period. Fewer plans and more listening tend to help.
Read up before you need it.
Short guides on the phases, on getting the date out of her without it being strange, and on what to do with the answer.
