Plenty of people want a period tracker that just tracks periods. You might be on the pill, or not trying for a baby, or you just don’t want a fertility forecast every time you open the app. You don’t have to hunt for a special app. Clue, Apple’s Cycle Tracking and Plum let you switch off the ovulation day and the fertile window, and your period forecast keeps working. Flo is the odd one out, because its own help page says ovulation days stay on the calendar.
We make Plum, so read our part with that in mind. What we say about the other apps comes from their own help pages, read on October 19, 2026.
Which period apps let you hide ovulation and fertility?
| App | Hide fertile window? | Hide ovulation day? | Where |
|---|---|---|---|
| Plum | Yes | Yes | Me > Cycle Preferences |
| Clue | Yes | Yes | More Menu > Cycle Personalization |
| Apple Cycle Tracking | Yes, plus its notifications | No separate switch | Health > Cycle Tracking > Options |
| Flo | Hides the chance of pregnancy | No, ovulation days stay | Menu > Cycle and ovulation |
How to turn off ovulation in Plum
- Open the Me tab.
- Tap Cycle Preferences.
- Turn off Show Ovulation and Show Fertile Window.
The ring on Home and the calendar then show your period days and the next forecast, and nothing about fertility. Both switches are free.
If you’re on hormonal birth control, you can skip the steps. Add the pill, patch, ring, shot, implant or a hormonal IUD under Birth Control on the Me tab and Plum turns both off for you. It also stops the “Ovulation may be close” reminder, since that method usually stops ovulation. A copper IUD doesn’t, so Plum leaves the settings alone for it.
Two things still mention ovulation. The phase guide still names the four phases, and ovulation is one of them. And the Cycle Reminders switch under Notification Preferences covers the “Ovulation may be close” heads-up as well as your period reminders. Our guide to tracking periods on birth control has more on what a period app can and can’t tell you on the pill.
How to turn off the fertile window in Clue
- Open the More Menu, the = icon in the top right of the Cycle View.
- Tap Cycle Personalization.
- Turn off Show ovulation, Show fertile window, or both.
Clue’s help page says the change saves right away, and it recommends hiding the fertile window if you take hormonal birth control or medication with hormones in it.
How to turn off fertility predictions in Apple Health
- Open the Health app and go to Cycle Tracking.
- Scroll down and tap Options.
- Turn off Fertile Window Estimates.
- Turn off Fertility Notifications too.
Apple lists these as two switches, separate from Period Predictions and Period Notifications, so your period forecast and its reminders carry on. If you have an Apple Watch, our page on whether Apple Watch tracks periods explains the temperature-based ovulation estimate on newer models.
Can you hide ovulation in Flo?
Only partly. Flo’s help page says you can turn off the chance of getting pregnant under Menu, then Cycle and ovulation. Once that’s off, it says, only ovulation days are displayed. It also says the fertile window disappears when you start tracking hormonal contraception. We couldn’t find a way to hide the ovulation day itself, so if that’s what you want, Clue, Apple or Plum will suit you better.
Why hide the fertile window at all?
The most common reason is hormonal birth control. The fertile window is worked out by counting back from your next period, on the assumption that you ovulate around the middle of each cycle. Most hormonal methods stop ovulation, so the window an app draws is a guess about something that isn’t happening. Clue recommends hiding it for that reason.
Other people just find it noise. If you’re not trying to conceive, a highlighted “fertile” stretch every month doesn’t tell you anything you’ll act on. And for teens, a period app that leads with fertility can feel like the wrong app. Our guide for teens covers that in more detail.
Whatever you pick, the fertile window was never birth control. It’s an estimate from your past dates, and how the fertile window is calculated shows why it can be off by days.
What about sharing with friends?
If you share your cycle in a Plum group, your friends see your period days and when the next one is due. They never see your fertile window or ovulation day, even if you leave both switched on for yourself. That’s a fixed rule, so there’s nothing to set.
