General information. Not a substitute for your doctor.
If you are not sure, leave it at 28 — the estimate already allows for that.
Cycle apps got the day of ovulation right at most 21% of the time. So we show the chance for each day rather than a single window.

How we calculate this
Worked out from what you entered. The days ahead are still a prediction.

And one day, another image
The same story carries on here. No starting over, no second app.
From the first cycle to the first year
Everything you log stays in one place, through every stage.
Trying to conceive
a fertile window shaped by your cycles
Pregnancy
week by week, appointments and tests
Baby

Memories
becomes a timeline, then a book
With you on the easy days, and the hard ones
The hard moments are where an app shows what it is. That is where we put the most care.
The two-week wait
The days counted to the test, without promising what nobody can know.
The day of the positive test
The due date comes from your own cycles, and there is a moment of your own to tell whoever you want.
If a pregnancy ends
Everything pauses, with care. Nothing is deleted, and the cycle comes back when, and if, you want it to.
Three in the morning
The feeding timer keeps the side and the time, so you do not have to.
And none of it goes to advertising companies.
In the end, memories
Everything you log is already a page. The album only gathers what is there.
