Everything in one playful app

Everything below is what the app does today — not a roadmap.

Everyone you care about

Add a profile for your partner, your sister, your best friend — a name, a colour, a photo and the day her last period started. That is all it needs.

Her phase, at a glance

The app places each person on one of five phases and shows the day of her cycle on a ring, with how long this phase lasts and what comes next.

A mood wiki for every phase

How she is likely feeling, what she will want to do and what she will not, what she will crave, and a worked example — warm, playful and never clinical.

It learns her real cycle

Log a period start, its end, ovulation or a symptom, and the app measures her actual cycle and period length from the log instead of assuming 28 days.

Dashboards that feel alive

One mosaic for everyone, and a dashboard of her own for each person: today's phase, mood trends, energy, sleep and the days ahead on a calendar.

Privacy mode in one tap

Hand your phone to someone and every name and face is masked across the whole app at once. Switch it on at every launch if you like.

Three steps to start

01

Add her

A name, a colour and the day her last period started. Add as many people as you like.

02

See her phase

The ring shows where she is in her cycle today, and the wiki explains what that phase tends to feel like.

03

Keep it accurate

Log the next period start when it happens and the app re-measures her cycle from what really happened.

Who can see your profiles

Only you. The profiles, dates, moods and photos you add are stored under your own account so they survive a new phone, and they are never shown to another member — there is no feed, no sharing and no public page. Nothing is sold, nothing funds advertising, and no analytics or tracking SDK ships in the app. Deleting your account removes every profile, log and photo together.

For fun, not medicine

Phases are an estimate from the dates you log, and the wiki is written to be warm and playful, not clinical. The app is not a medical device, gives no diagnosis, and must never be used for contraception or to plan or avoid a pregnancy. Everyone is different — when in doubt, ask her.
