Who it's for

Evidence note: The recent reviews skew heavily negative, particularly regarding unexpected charges and ads, which contradicts the high lifetime rating.

- [R6] Period: I love thish app so much like you get to now when you going to get your period
- [R12] On point guesses: I love this app. The tracker is mostly on point. checking in on how we feel every time I open the app makes me feel like it’s a step to it getting to know me more about my cycle!
- [R18] Love it but too many ads: I love that it has a teen plan and that it teaches us about our bodies I just wish that there wasn’t so many ads
- [R22] AMAZING APP.: I recently got my first period and decided to try out this app! There’s symptom logs, a cute little calendar, positions to relieve period cramps, and even an at home breast exam tutorial! Amazing app, honestly!

- [R11] for younger people: I’m a 10 year-old I got my period and this is really helping tracking it
- [R16] Slay: So I just got my first period and it was hard but this app is helping a lot
- [R50] Wonderful and reliable app!: I absolutely love and enjoy this period tracker Calendar. I’ve used it for years. Every time I get a new phone all the information transfers over. It really helps me stay on track with the things that I need when it comes to my womanhood. Thank you! I definitely recommend this app.
- [R31] Must have!: It’s pretty spot on with its predictions. It took a few months of entering it in. I like having a partner feature. I don’t plan on getting pregnant. I like my man knowing my cycle.
- [R14] Price: So I’d like to say most of this app is free. It’s free to download and it’s free to use. But behind doors. They charging u almost 50$ monthly that I keep getting charged on apple. For an app that supposedly is free. I don’t recommend downloading or using unless u want to get charged. Need I remind u it never said anywhere id get charged to use the app.
- [R333] False advertising: Says the app is free just got charged £35.99 for something I did not agree to how can that price even be justified
- [R346] Took £39 - A subscription trap: Really gutted. I’m struggling with money as it is. Lost my job due to seizures and getting in to debt :( I really could have done without this. Got in touch but no reply. If this got sorted, I’d happily change the review to 5* because the app itself is actually great. Just so upset to be charged so much money that I really need.
- [R352] Took money: Took £36 out my account without me knowing don’t use this app
- [R161] Somewhat accurate but has too many ads: If it’s a tracker, why so many ads
- [R195] Used to be good: I’ve had this app for years and loved it. Although, recently the amount of adds is so frustrating, that it’s almost not useable! Whatever you click… add. I’ve started using period tracing in my health app, and I think I’m going to stick to that one from now on!!
- [R424] Too many ADS!: I gave 2 star because apk has too many ads!
- [R469] Used to be good: Used to be a great app but have changed their ads so you have to watch a video every time you open the app or switch what you are looking at, makes it unusable. I am deleting and finding something else to use
- [R5] Confusing: Honestly, I do not like this one go back to the old one. This one is too confusing.
- [R118] 😬: confusing.
- [R445] Down grade: This app used to be so amazing now. I loved the previous interface. But it’s so so confusing now
- [R526] Ads: Good app, but confusing features and ads. Why are there ads in a period app?
- [R177] I lost my data: I have a new phone now and have had to download the app again. But my data for the past 3 years have been transferred over and it’s strange. I know I backed up my data and I’m linked to the same apple account yet it’s missing.
- [R294] 😢: I had used this app for years free, I had to reset my phone and lost all my data, also ask me to pay now. Disappointed that there aren’t free trackers as this was my go to.
- [R340] Restoring data is not possible: absolutely no way to restore data once its lost and none of the options to “restore data” actually do anything
- [R46] Cannot see when intercourse occurred: You cannot see through your partner's account when your woman had intercourse. · translated
- [R158] polyphobic: more than one partner linkable when🥹🤞 or a friend mode
- [R241] Suggestion: Pourquoi ne pas créer un chat avec ma partenaire ? Pour mieux garder l'attention et la proximité virtuelle. Une session où je peux lui de rappeler de cocher ses humeurs et autres, si elle ne le fait pas.
- [R404] Partner mode doesn’t work: Partner mode doesn’t work for me and my partner. Please work it out
- [R257] New phase in life means it’s no longer useful: Other than the stupid pet thing this has been a good tracker, up until menopause. There is no way I can put ‘missed period’ without pretending I’m pregnant. It has technically not added a period but it has started counting from day 1 again. For this reason I will be deleting it. 2 stars because women in this stage of life often feel forgotten and this
- [R350] doesn’t work for I rregular periods: It’s not good with irregular periods at all. If your period doesn’t come on the day the app assumes it will, the app will mark the day as a period day until you remove the period day it put in the calendar for you. Also once you put the actual period in, it changes the ovulation date leaving me very confused as to when ovulation actually was (i don’t need to kn
- [R456] Bad: I’ve been using this for years then I realised , I key in my period every single month and it never matches my next period not even close . It keeps giving me 40 days gap on my next period which it delay backward on my next period . I don’t know how this apps works counting the cycles . Delete bye .
- [R523] It sucks: When my period came a day earlier a day late it did not adjust which made it off and it surprised me when I got my period a week earlier than the app said
- [R102] can’t search tags: i’ve been using this app since 2017 and really have just been using it for the period tracker option which has been great. but lately i’ve been using the “diary” more often to track my cravings. i created my own tag “#appetite” but when i search in the timeline for this tag, it says there’s “no search results”. also i wish we could add custom symptoms, moods, etc. because i’m al
- [R780] Good app but some UX changes would help: Good app with wonderful core functionality. Four main requests though: 1. Ability to add the four-stars scale of severity on custom tags. 2. Ability to track emotions like symptoms. 3. Ability to easily view the dates that all symptoms have occurred or which ones tend to occur together. 4. (Most important) Please please please can the emotions and symptoms
- [R60] Do not download!!!!: The app was fine at first but then I couldn't get out of the app so i turned off my device and I couldn't get out of the lock screen or use the shortcuts on the lock screen so I had to reset it. Turns out i got a virus on my device😭😭
- [R252] Please be careful: This app is great. Very accurate and very good. But please be careful today I was taken to a page on safari by the apps trying to get me to click a link to clear viruses given to me by the app. Obviously this is a scam and I did not click this link. If you use this app because it is great make sure you don’t click anything that looks suspicious.
- [R256] Virus message: Logged on this morning & the message button was flashing red. Clicked on it and it opened a Google message with a count down timer saying my phone had been infected with a virus and I had to click the button below to save my files etc I deleted the app but wanted to notify developers - seemed linked to safari as same message was there when I went to safari to search if app had been
- [R370] Cookies: I've been using this tracker for years, also through my pregnancy. Then one day, the request for hundreds of cookies and trackers popped up. This is a deal breaker for me. What a shame. I would have preferred to pay for the app than to sign my privacy away.
- [R264] Good app: I’ve used this app for years and it helps me track my period, PCOS symptoms and my medication, which I can share with my partner. Recently though I’ve been getting daily notifications for a quiz that not only am I not interested in doing, but I also can’t seem to disable it or stop the notifications. Not sure if it’s a bug but if there’s an option to disable to quiz, that’d be perfect.
- [R632] Decent enough: Something that just bothers me is they have informational stuff which could teach you a lot of things about your body with symptoms and such but you have to pay to even read them… which I find absolutely dumb? I don’t understand why I’d have to pay to read stuff that I could deep search about or ask a doctor about, and honestly it would help if I were to even have access and read so
- [R28] Great: I love this app. Almost head on accurate all the time.
