Up to three people
You, her, and one more. Each person gets their own color, and that color follows them everywhere — calendar, reminders, widgets.
Multi-person period tracker
You have a cycle. So does she. Know whose week it is — before it arrives.
Chapter I · The Overlap
When you share a life with someone who also has a cycle — your girlfriend, your daughter, your roommate, your sister — your hard weeks don't politely take turns. Sometimes they land on exactly the same days.
Most period apps are built for one body, or for a partner who just watches from the outside. Hers is built for two people who are both in it.
One of you keeps the calendar — you log her days next to your own. She doesn't have to install anything, and there's no account to connect.
Chapter II · Try it
Chapter III · What it does
You, her, and one more. Each person gets their own color, and that color follows them everywhere — calendar, reminders, widgets.
Not just yours. Hers predicts each person's next period and PMS window, so you can see the collisions coming.
Set PMS and period reminders per person.
A tiny question, answered every morning: is anyone on their period today?
Syncs with Apple Health, backs up through your own iCloud.
Pick a theme — it repaints everyone's dots.
Chapter IV · Who it's for
Me and my girlfriend
Two cycles that don't sync, and one week a month where you both need someone to be the calm one.
Me and my daughter
Her first year of this. She forgets to write it down — you don't.
Me and my roommate
Not a couple. Still worth knowing why the kitchen felt tense on Tuesday.
Me and my best friend
Trips, festivals, the beach weekend. Somebody has to look at the dates.
Just me
One person is fine too. Hers works alone, and waits quietly until there's someone to add.
Chapter V · What's not in here
Hers has no advertising, no social features, and no community timeline. There is no version of this app where a stranger sees your calendar. It syncs through your own Apple Health and your own iCloud — we don't run a server that holds your cycle.
Chapter VI · From the people using it
“It's so simple I upgraded to Pro right away. My wife and I had been using another app — too cluttered, and between work neither of us had the energy for it. This one just solves what two people need.”
“I love the home screen — the type, and the color palette across every screen.”
“A wonderful app for women — and one that respects them. Practical, beautiful, and fairly priced.”
“Clean and beautifully simple — and the predictions have been accurate for me.”
“So easy to use — and the free features are honestly plenty for me.”
