Please post an update. I will change my review. -- Littlewasper, 2026-05-17 ### ***-- "Simplicity Request" Could you please offer the ability to only track periods on the calendar without seeing the purple fertility days? That would be great. -- ZappityZapZap, 2024-06-12 ### *---- "Very basic" Every time I try and open the calendar on this app it closes the app it is just too basic for me -- Godfamilyniners, 2024-01-04 ### ***** "I love it" I love this app because I use to have flo and it was a good app but it was a little bit complicated but this app is not complicated but I love it and every time it tells me exactly when I’m going to start my period and when I’m going to end it and so far it’s been right -- z12oey, 2023-12-31 ### ***** "Very simple like it should be" I picked this app because the developer said your data doesn’t leave your phone. (Period math isn't so complex it needs to live on a server! I’m disturbed by all the other apps that take your info.) I was inclined to believe it because the the interface looked dignified and simple, made by one person and not a data mining company. App works great. I open the app to check when my period is supposed to start, I open to log when it does start, and I open to update the log to when it actually ended. You can adjust your standard period length and it will update its predicted dates, and if your period changes this month it will update future predictions accordingly. -- alsoadeveloper, 2023-10-01 ### ***** "😘" I love this app -- jameaka74, 2022-12-18 ### **--- "Nonexistent accessibility, unintuitive design" My eyesight is not the greatest, and this app has absolutely no accessibility. The text is inconsistent, tiny, and very low contrast. This app is one of the prettiest on the market—and I can’t see any of it. Additionally, the UI is not at all intuitive. I can’t find a place to put in past periods, the calendar seems to only let you select days you have your period (what if I want to log symptoms or events on literally any other day?), and the symptom selections are very basic. 5/5 pretty 0/5 accessible 2/5 interaction 2/5 period prediction -- HeartofGalaxies, 2022-06-03 ### *---- "Could be great" Best design out of all the apps in this category- ie not designed for a 12 year old. Howe ever it’s poorly made. The tracker is useless and glitchy. I e been using this app for over a year and if you just let it run it’s course and you have a consistent period then it’s OK. If you want to actually record start and end dates good luck! The app literally will not allow you to alter period start and end dates. It’s basically impossible to use. I think the most recent update actually made it worse. Will be deleting. -- Rose- 29484$482&28!43&&4&, 2022-01-23 ### **--- "Glitches" It often won’t allow me to put in dates that have already past. It’s December 1st and I’m trying to log that a period ended two days ago, November 29. It will not allow me to do that—I guess it’s a glitch that won’t allow you to record something from last month??? Frustrating. -- greenpig96, 2021-12-02 ### ***-- "Love but Buggy" I love this app, and it pains me to just give it 3 stars. Right now, every time I try to log in and record my period in the Calender, the app times out. Please fix this soon! -- Sequinfishbait, 2021-11-16 [View all Period Diary reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Period Diary In-App Purchases | Item | Price | |------|-------| | Period.
