Please rectify ### 5/5 — Brilliant *2021-03-15, version 9.5* Have been using this for 11 years and has been so brilliant and reliable. ### 5/5 — My go to app *2021-02-17, version 9.5* I’ve been using this app for 10 years. It is always reliable, always relevant, and helps me track what I need. Love it. Recommend it to all menstruating people. ### 4/5 — Good app *2021-02-14, version 9.5* Overall a good app, I’ve been using it for some years now. The only thing that’s lacking is a graph to help analyze the stats over a longer period of time. ### 2/5 — Import fail *2020-12-26, version 9.5* I am having difficulty importing my data. I was able to sync it to fertilityfriend.com but when I try to import, I get a connection/no internet error. Any idea what I could be doing wrong? ### 5/5 — [Fixed] iOS 14 not opening bug *2020-11-12, version 9.5* I updated to iOS 14 and the app would not open. Could you check on this issue please? ^^ the above issue has been resolved. Thank you. ### 4/5 — My app won’t open anymore *2020-11-07, version 9.3* I’ve been using this app for such a long time and I love it but now it won’t open for me anymore. I’ve reset my phone, checked for updates on the app. I don’t want to delete and reinstall because I don’t want to lose my cycle data 😩 HELP ### 5/5 — This app is such a gift *2020-11-01, version 9.3* I’ve been using this app for at least 12 years and it has transformed my understanding of the female reproductive system. I am a nurse and the way this app explains the amazing coordinated events that take place every month in our bodies gave me an even deeper understanding and appreciation of the dynamic human body. I have PCOS and struggled to get pregnant and charting my basil body temperature was a game changer. My daughter is now 9 years old :-) Charting my temperature was by far the most accurate method! I also cross referenced with the ovulation kits and was able to pinpoint exactly when I ovulated with the slightest increase in body temp. I highly recommend this app. ### 4/5 — App stopped working *2020-10-16, version 9.3* Used for many years, and it suddenly stops working. Wont open up. Help!!!!! ### 5/5 — Accurate and Free *2020-09-23, version 9.3* I’ve been using this app since 2012. I recently went looking for a fertility app and saw the outrageous fees being asked to track periods. I’m grateful for this app. It’s accurate and easy to use. I love the simplicity and that they’ve stayed true to women’s health and not looking for the dollar. ### 3/5 — I need help *2020-06-19, version 9.3* I need help with my app I been used it for many years and now is not working . I am trying to open it but it not working :( ### 5/5 — Does the job! *2020-06-07, version 9.3* I’ve been tracking periods with this app for 10 years (literally). Super easy; works great! I love having all that historical data. I’ve never experienced and bugs or issues with the app, and I’ve used it across several phones and iOS versions. ### 5/5 — Extremely Reliable App *2019-11-12, version 9.3* This app does exactly what it says it will do. I haven't experienced anything bad with the app until this morning after using it for years. Today the app just wouldn’t open and I needed to log in my cycle. I have record everything in this app and to have to go somewhere new to start with a new app is gonna be crushing. I was always able to go back to review info in the app whenever need be. Please fix this issue!! Other apps are not so easy to toggle. ### 4/5 — Needs to integrate with Health app *2019-08-09, version 9.3* Title says it all. When my dr asks for information, I don’t want to have to switch back and forth between apps. I also don’t want to change apps(or hand-key years-worth of data). Devs need to add the ability to export to iOS’s native Health app (now that it finally caters to the other 52% of the population), so when we’re with our doctors we can have it all at our fingertips (or even just hand it over—there are very tech-savvy drs out there). ### 5/5 — Great and reliable app! *2019-05-03, version 9.3* I’ve been using this app for years now. It’s been with me through so much and never let me down. No crashes, no bugs, just clean and easy to use interface, discreet app logo and name. Oh, and a cute cat wallpaper start up page you can select :) Can’t believe that it’s not the most popular app of its kind in the App Store. Give it a try because it’s definitely worth it, and spread the word, your friends will thank you! ### 5/5 — Amazing App *2019-04-07, version 9.3* I don’t like complicated apps and this app is super easy and great at tracking. I’ve been using this since 2009 and it has all my logs saved. I have my 11yr. old using this same app. The other apps were too complicated. You can switch off of things you don’t need to track like fertile or ovulation times. ### 2/5 — customer support *2019-02-05, version 9.3* i have tried several times to contact customer support to no avail. i have been using the app for many years and just wanted to be able to log in using a new device. ## Most critical reviews (10 lowest-rated) ### 1/5 — Over 14 years of records gone in a flash *2023-10-15, version 9.9* Very disappointed to see all my data disappear. Given I’ve used your app for over 14 years without changing a single thing in all that time of how I used the app then to suddenly lose everything is a real kick in the guts. Not reliable at all if I can’t see my stats. I guess at the end of the day pen and paper and following the Billing’s method will always trump technology. ### 1/5 — Lost years of data!! *2020-10-22, version 9.3* I went to open the app after getting a new phone (used the backup from my old phone to get it set up) and over 10 years of data is gone!! I’ve upgraded my phone before and this has NEVER happened! I am devastated!! Two pregnancies worth of notes, 10 years of period data, 10 years of migraine-tracking notes, plus other medical data- all gone. I relied on this app for over a decade!! What can be done to fix this?! ### 1/5 — What happened? *2019-03-27, version 9.3* I’ve been using this app for over 10 years, and all of a sudden I can’t log in. It keeps saying incorrect code, and I’ve NEVER changed it. I’ve asked to reset my password, but I haven’t received an email. What have you done? Have I lost all of my data for the last 10+ years? How many emails do I have to send before you’ll reply to me? ### 1/5 — Crashed, MONTHS of data LOST *2018-05-13, version 9.2* I was really enjoying this app until I set a passcode/face ID and the app immediately crashed and force closed. I couldn’t re-open the app, each time it would glitch out and continued to immediately force close. I restarted my phone, including a hard reset. There was no option to back up data to iCloud or link email in hopes of restoring data if I had to uninstall/reinstall the app. I ended up losing months of important data and am devastated. Not a reliable tracking application!!!!!!!!! ### 1/5 — Silly little app *2018-03-04, version 9.1* This is the worst thing on earth. Why would anybody want to use. If people say it is great and brilliant then they are wrong don’t listen to them. ### 1/5 — LOST ALL YEARS OF DATA *2017-08-04, version 7.8* Great app but lost all data when I reset my iPhone from iOS 11 beta back to iOS 10.3.3 Is there a way to get my data back? Very accurate in tracking cycles. Doctors usually ask when was your last cycle so this is handy. Also, you could take inventory of your sanitary supplies and pills before your period hits. I especially like the notes section for writing details. ### 1/5 — Can't set up password after updated ios10 *2017-01-12, version 7.8* I changed the device to iphone 7+ but can't set up password after installation FMC and after updated ios10.2 ### 1/5 — Last update is disaster *2015-04-04, version 7.4* It was a wonderful app but last updated destroyed it! If we add a note to a date and then we delete it....the note mark stays forever in the calendar view! I have ended with a calendar full of note marks but if u open the specific date it's empty! Moreover, i'm on pregnancy mode and today the app notified me to expect my Aunt Flo!!! What??!! Please fix it! ### 1/5 — Для разработчиков... *2013-09-11, version 6.4* Пользовалась этой программой до беременности - все отлично. Но! Нет функции - беременность и роды. На это время надо, что бы цикл прерывался, а программа все считает деньки... Русский язык нельзя ли добавить? ### 1/5 — I hate this damn application! *2010-08-18, version 0* I hate this application soooo much!!!! I kept on tracking my period for over 6 months then suddenly, everything was deleted!!! Will never trust this application ever!!!! ## Most praised reviews (10 highest-rated) ### 5/5 — Simple and effective *2026-06-18, version 10.0* I’ve been using this app for over 12 years. It has everything I need without annoying things I don’t. ### 5/5 — シンプルで使いやすい *2026-01-29, version 9.9* 色々入れてみましたがこれが一番気に入ったので10年以上使っています。おすすめです。 ### 5/5 — pretty good ngl *2025-09-07, version 9.9* great app for younger ppl, simple and straightforward. ### 5/5 — Great app! *2024-07-09, version 9.9* I have been using this app for over 15 years now and it’s great. I like it’s simplicity and the fact that it’s user friendly. I’ve had 2 children in the meantime and it helped me keep an eye on my fertile days as well as my cycle. Stats are great and always useful if you need to remember the last day of your period ☺️ ### 5/5 — Perfect practical easy to use *2024-01-15, version 9.9* Straightforward app with everything I need. Simple to use and very well designed. I’ve been using it for 12 years at least. No bugs no crazy updates where your data is changed around. You can add symptoms feelings weight etc if needed. Tracks days since last cycle, body feels and emotional ones. Shows info in charts if you want or on calendar. Displays information clearly. No clicking through weird complicated pages. I can go back through my data easily. Shows trends by year/month etc with few taps. I am never confused while using this app. It’s easy simple complex brilliant I love the look too. No pink!!! Easy to follow use and best app out there. I used their other product fertility friend for getting pregnant, which was hard bc of endometriosis issues plus. It was simple and brilliant ### 5/5 — Отличный календарь *2023-02-28, version 9.8* Пользуюсь уже много лет, отлично предсказывает дату ### 5/5 — Best period app hands down. *2021-11-10, version 9.6* I’ve been using this app for at least 8/9 years and I refuse to use others. Easy to use and accurate each month. Please keep it around! ### 5/5 — Amazing *2021-10-03, version 9.6* I’ve had this app for a few years now because my periods would show up whenever they felt like it. At first the app would give me the standard 28-day cycle, but it started learning my body. I’ve been inputting every cycle and it’s now properly guessing when my next cycle will begin and it’s been nearly correct every time! Kudos to the developers ❤️❤️ ### 5/5 — Don’t ever stop updating *2021-08-21, version 9.5* I looked back today. This app has been helping me keep track of the madness since 2009. I downloaded and sync’d the Fertility Friend app since you haven’t updated this one in 9 months. The other hasn’t been updated in 2 months. My doctor and I are using this to track my progress. Please keep updating both! If you want to sell this app, reach out to me. This is how much it has helped me over the years. It needs to live on. ### 5/5 — Extremely useful *2021-08-10, version 9.5* Being using this app for years to help me remember my cycle dates. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
