A period tracker for iPhone
Your cycle, drawn plainly and kept on your phone.
Femata draws each cycle from the days you log, and shows the next expected period on a calendar.
No account. No ads. No server holding your cycle.
Try it. This phone works.Example data
One line of days, with each part of the cycle resting on it as a half disc.
The picture is drawn from what you log, so it is as long as your own cycle. Flat ink is what has happened. A line screen is what is expected.
LoggedExpected
The days you logged, in flat pink.
Day 1 to ovulation, in rose.
Where the 2 halves overlap. The teal dot is ovulation.
After ovulation, until the next period, in apricot.
Expected, so it is a line screen.
When your period starts, tap Period today.
The day is logged and printed on the picture in flat ink, and the dates that follow move with it. You can set the flow to light, medium or heavy. Each change offers Undo for 5 seconds.
Example data
Write a note on any day, and make marks of your own.
A note is plain text, up to 500 characters. A mark is a word you choose, such as Cramps or Good day, that goes on a day with one tap. Press and hold the calendar and slide across it to read back through your days.
Example data
Each phase has an entry, written the way a small dictionary would write it.
The corner of the page takes the colour of the phase you are in. Under it, the entry says what the phase is and what many people notice in it.
[phase, the first days of a cycle]
The days of bleeding that open each cycle.
A period is the lining of the uterus leaving the body. It starts when the 2 main cycle hormones, estrogen and progesterone, are at their lowest, which is a large part of why energy can dip in these days.
[phase, after a period ends]
The stretch between a period and the fertile window.
After a period ends, estrogen starts to climb while the body prepares an egg for release. Rising estrogen tends to lift energy, mood and focus a little more each day.
[window, about 6 days]
The days before ovulation, and the day itself.1
Estrogen reaches its peak and an egg is released, which is called ovulation. The few days before ovulation and the day itself are when pregnancy is most likely. Femata is not birth control, and its dates must not be used to prevent pregnancy.2
[phase, the 2 weeks before a period]
The stretch after ovulation, until the next period.
After ovulation, progesterone rises to prepare the body for a possible pregnancy. If there is none, both hormones fall in the last days before a period, and that fall is what brings on premenstrual symptoms for many people.
Share your cycle with 1 person, and choose exactly what they see.
Each thing you keep is in one of 2 lists: what your partner can see, and what only you can see. A switch moves it from one list to the other. Their view is read-only, and it follows along as you log.
Example data
Your period days, your phase and your expected dates, unless you turn any of them off.
Flow, notes and each of your own marks stay private unless you turn them on, one by one.
Shared through your own iCloud, encrypted, with 1 person only. Femata runs no server and cannot read it.
You can stop at any time. Stopping removes the shared data from the other phone.
Together is $19.99 a year and includes Femata Pro. The person you invite installs Femata for free, and needs an iPhone.
Your cycle is stored on your iPhone. There is no account to make, and no server that holds it.
Period days, flow, notes, marks and settings are stored on the iPhone and in your own iCloud or device backup, under the backup settings you chose with Apple. The developer cannot see, access or recover them.
Subscriptions are processed by Apple. A subscription service, RevenueCat, checks whether one is active. It receives the purchase receipt and a random ID, and never receives cycle data.
