I have been using this app for YEARS! (Approximately 5-6). It is fantastic and helpful, especially when I go to my OBGYN for a check-up because I can log my symptoms, gauge their severity, and share these findings with my doctor. Also, the free version is effective, and there is not a bombardment of ads!! I highly recommend it!
as a woman with PCOS period tracking is a struggle. I've never found apps that work until this one, I've tried many apps but this one has been the most accurate for me over the last 3 years. I love that you get features without having to pay, I hate the way apps do women that way. it's always on time and not a regular schedule but MY regular and that's huge for me. overall just love the app and definitely recommend!
I've used it for 8 years now. It has kept record of 3 pregnancies for me, predicted my cycle changes very accurately, and reminded me on time! This is a very good app! Smooth layout. I'm sure there are other decent cycle apps out there but this one has been the most logical one from the beginning so I have stayed with it! 8 years later it has still not disappointed. Thank you!

I love that I have a dedicated place to always look up when the first day of my last period was. As a female, this is what any doctors office asks every single time, even if i wrote it on the intake form! There are a lot of features to use in the app to help keep track of and find patterns. Whether you're single, with a partner, avoiding pregnancy or trying to get pregnant. You can put moods, cravings, amount of flow, and more.

Simple and straightforward. There are not too many ads and a clear design. I just wanted an app to alert me when my cycle was getting close and to keep track of it, which this app does. It also lets me know what my emotional state might be due to hormonal changes. You can imput your mood, bloating, cramps, etc., as well to help keep track. It will let you know when you are ovulating to help with conception. I have had this for about 3-4 years and have never needed anything else.

Been using this app for monthsss ( don't remember how long :3) and it's the best thing I've come across. Due to something traumatic that happened to me in the past I decided to try tracking my period and this was the first app I decided to try and guess what? I wasn't in any way disappointed. Barely any ads (well for me) and works amazing even though I use a free account lol. You guys are amazing! KEEP IT UP ♥

I've been using this Period Calendar app for a while, and it's been really helpful. The predictions are quite accurate, the interface is simple and easy to use, and the reminders always come on time. It helps me track my cycle, symptoms, and ovulation without any confusion. I highly recommend this app to anyone looking for a reliable period tracker.

FAQ
Frequently asked questions
What is Period Tracker and Calendar?
Period Tracker and Calendar is a menstrual cycle tracking app that helps women monitor periods, predict ovulation, track fertility windows, and log symptoms such as cramps, mood changes, bloating, and basal body temperature.
The app is available on iPhone and Android and can be used without creating an account.
Who is Period Tracker and Calendar for?
Anyone who wants to understand their own cycle — whether you're tracking for general health, trying to conceive, newly pregnant, navigating perimenopause, or logging your first few cycles as a teen.
How does the app predict periods and ovulation?
Predictions are calculated from your own logged cycle history rather than a fixed 28-day assumption.
Prediction accuracy typically improves the more cycles you log, since estimates are drawn from your own history rather than a fixed average.
Does the app work for irregular cycles?
Yes. You can log periods and symptoms even when timing is unpredictable — predictions are simply less precise until more cycles are logged, the same as with any cycle-tracking app.
Can I track ovulation?
Yes — the app estimates your ovulation day and fertile window based on your own logged cycle history.
Can I use the app while trying to conceive?
Yes — TTC mode surfaces fertile-window and ovulation-day estimates in addition to the standard cycle tracking.
Is there a Pregnancy Mode?
Yes — pregnancy mode lets you track week by week once a cycle turns into a pregnancy; your prior cycle history stays saved for when you return to cycle tracking afterward.
Is there a Perimenopause Mode?
Yes — perimenopause mode is built for longer, less predictable gaps between periods, so predictions adapt as your cycle changes.
Is Period Tracker suitable for teenagers?
Yes — teen mode is a simplified view aimed at someone tracking a period for the first time, without the fertility-focused features aimed at adults trying to conceive.
