That would be great. ### 3/5 — Slight problem *2024-02-20, version 2.0.15* The problem is that we’re it says temperature, I think it’s in Fahrenheit. And I’m Aussie so just sorta left it at the same temperature as it started. Also another thing I feel like this app is more suited for older than 35 year old woman. I will say I’m gen z and quite a bit younger than 35. I guess what I’m trying to say is maybe there could be different countries/age language changes. And if you’ve gotten as far as reading all this THANK U <3 much love from Australia 🇦🇺😀 ### 2/5 — Not worth the premium price but good for a free app *2023-12-08, version 2.0.15* I like the aesthetic and good free I guess. I bought it and immediately regretted it because then the app kept crashing. I’ve requested for a refund. Not worth it ### 3/5 — Good app but need to have time zones *2023-07-17, version 2.0.15* Please allow for different time zones to be chosen the dates a wrong and confusing. Thanks so much ### 2/5 — Nonexistent accessibility, unintuitive design *2022-06-03* 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 ### 2/5 — Problem *2022-03-12, version 2.0.15* I don’t really recommend this app. It was okay for the first 7 days ,worked how it should , I wasn’t really sure how it worked exactly as the colours and there meaning weren’t clear. But then after 7 days I went to go to “calendar “ and it completely glitched out of the app. And from then it would do the same thing every time . I thought if I uninstalled and then reinstalled it again it would work but the same thing happened again. I then deleted it and got another tracker ### 1/5 — Could be great *2022-01-23* 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. ### 1/5 — Not impressed *2022-01-15, version 2.0.15* It won’t allow me to properly record my period start and end date - it’s recording the info incorrectly and is therefore pointless. I’m deleting it. ### 2/5 — Glitches *2021-12-02* 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. ### 3/5 — Love but Buggy *2021-11-16* 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! ### 1/5 — doesn’t work *2021-09-03, version 2.0.13* it doesn’t let you set your period end date don’t get this app ### 2/5 — Can’t set last period end date. *2021-06-29* I just downloaded this, happy to find an app that doesn’t track ridiculous things like kissing. I’d even happily pay $5 to remove ads if it works. However, the app defaults to the current date for your last period and the number of days out your period typically lasts as the end date. I can change the start date to the actual date of my last period, but i cannot change the end date. Every time I try, it goes back to the last day of the month, indicating a 27 day period... There is no support on the website. ### 1/5 — INSTANTLY won’t work *2021-06-20, version 2.0.12* Got excited. A period tracker that doesn’t track you and doesn’t want my appleid info to be able to access MY data (talking to you, iPeriod) without all the extra crap! YAY! Or not. When trying to input my last period, it let me enter the start date 05/23/21, but would not let me enter the end date as any later than 06/25/21. A period app that assumes I have a 32 day period (NOT a 32 day cycle, but a 32 day PERIOD) as soon as I open it is clearly DEEPLY flawed. My device is brand new and up-to-date. ### 1/5 — Bug from first minute *2021-02-28, version 2.0.10* Like the idea of no need for an account, that why I downloaded it, but I couldn’t even set it up, it wouldn’t let me save the period end date in the same month of start date. I have to delete this app. ### 2/5 — Problem *2021-02-06, version 2.0.8* Couldn’t even get started with this app as it wouldn’t let me log an end date for my last period that was in the same month as the start date. How long does it think periods are? ## Most critical reviews (10 lowest-rated) ### 1/5 — App Issues *2026-05-17* I have really liked this app; however it has stopped working. Please post an update. I will change my review. ### 1/5 — Very basic *2024-01-04* Every time I try and open the calendar on this app it closes the app it is just too basic for me ### 1/5 — Not impressed *2023-12-10, version 2.0.15* I go to set up for first time and there is a giant add covering the whole screen, it was for a dating site. the two people had their heads leaned into each other and they were both men! Which woman was that directed to? Totally immoral anyway seems tough to find normal things these days. Will not use a company that promotes immorality. Will keep looking for something wholesome. ### 1/5 — NO *2023-10-06, version 2.0.15* DONT LIKE THIS APP ### 1/5 — Too many ads *2023-09-06, version 2.0.15* The amount of ads that pop up when I’m just trying to log dates ### 1/5 — Poor *2023-01-24, version 2.0.15* Very slow and not working ### 1/5 — doesn’t work *2022-09-26, version 2.0.15* crashes every time I try to log a period. Feels misogynistic. ### 1/5 — Inappropriate *2022-09-06, version 2.0.15* This is a 12 ur old using this and it’s entirely inappropriate!!! ### 1/5 — Calendar glitch *2022-07-30, version 2.0.15* The app will not let me change the end date of my period. When I try to edit it auto sets it to the current date, throwing off my tracking and essentially making the app useless. ### 1/5 — Changing cycles *2022-04-25, version 2.0.15* I am trying to add the end of my cycle and it doesn't let me change it. I am irregular so the time varies and isn't stable. I ended two days ago and want to change my end date, and it only lets me “end” it after today and on, not before. This is highly annoying, especially since o i paid for this app. ## Most praised reviews (10 highest-rated) ### 5/5 — I love it *2023-12-31* 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 ### 5/5 — Very simple like it should be *2023-10-01* 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. ### 5/5 — Nice! *2023-06-19, version 2.0.15* This is a fine app that is useful and doesn’t have too much details. I love how you don’t need an account so you know for sure you are private. You do not have to pay for simple period tracking which is good. There IS a premium, which allows much more options. But overall, a good period tracking app. 💗🩸 ### 5/5 — Free and does the job so well *2023-06-02, version 2.0.15* No account needed. Ads aren’t too annoying and it’s the only one so far that allows period tracking which is all I want. It’s good that if you want ovulation & fertility tracking you have the option to pay. Other apps were charging even to track periods 😡 Very happy. ### 5/5 — 😘 *2022-12-18* I love this app ### 5/5 — Cute *2020-06-29* Got it cuz my sister did. ### 5/5 — I would recommend it *2020-04-14, version 2.0.3* You don’t have to be over 13 to use this app which is great for me and everyone who has gotten their period earlier than others, it gives you information about different phases of menstruation and tells you what happens during them to you, it also can let you change the date of when your period starts if it starts late, early or on time. Overall, anyone who has their periods should use this app I would 100% recommend it. ### 4/5 — Pleased *2020-04-02* I am pleased with the app. It is informative and helpful. However my confusion lies in the color coordinating. The period diagram has pink that then turns white and then purple. I don’t understand what the color coordinations are indicating. ### 4/5 — Great idea but needs location accuracy *2019-12-06, version 2.0.2* Love the visual display of the cycle and fertile days. But this app is set to a time zone that isn’t mine, so I get my period a day ahead of the day the app is set to, and therefore I can’t tap the day it starts on the calendar. Let me put my time zone in manually! ### 4/5 — It’s simple and gives you what you want strait away *2019-11-23, version 2.0.2* This app is really good because it is under 13s and it’s really hard to find a tracing app that is under 13s and when you first go in it says please put in your latest period and that means right then do just ad heads up but once your in the app you can change it and if you want to know how many days until you’re next period than you can just click on it and the that’s the first thing you see and you don’t need premium to be the best app I’m doing fine without it so definitely recommend --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
