Knowing: Ovulation & Period

Knowing turns what your body is already telling you into one clear answer a day.

SCAN YOUR OVULATION TEST Point the camera at an LH strip and Knowing measures the test and control lines for you — no more squinting at two pink smudges in bad bathroom light. It plots your surge across the cycle so you can see it coming, not just notice it after the fact. The photo is deleted once the measurement is taken.

THE SIX DAYS THAT MATTER The fertile window is six days long and ends on the day you ovulate. Knowing shows you where you are in it — today, in plain language, above the fold — and builds its estimate from what you actually log: your periods, your tests, your temperature, your cervical mucus.

WHATEVER YOU ARE HERE FOR Four modes, and the whole app changes to match: trying to conceive, pregnant, just tracking, or avoiding pregnancy. Pregnancy mode follows your weeks, your due date and your blood pressure readings.

LOG WHAT MATTERS, SKIP WHAT DOESN'T Flow, cramps, mood, mucus, temperature, medication, blood pressure, notes. One tap each. Nothing is required.

EVERY CLAIM HAS A SOURCE Where Knowing tells you something about your body, it tells you where that came from and how strong the evidence is. Where the science is weak, it says so — including the moon, which is shown because it is lovely, and clearly marked as decoration that predicts nothing.

ASK, PRIVATELY Ask questions about your own cycle and get answers from Apple Intelligence running entirely on your iPhone. Nothing is sent anywhere.

BUILT TO BE PRIVATE There is no account and no sign-up, because there is no server. Your cycle data lives on your iPhone. Optional iCloud sync keeps it in your own private iCloud, and you can lock the app behind Face ID and export an encrypted backup whenever you like.

Knowing is not a contraceptive and does not diagnose anything. It is a record of your body and a clear reading of it.
