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
App Issues
I have really liked this app; however it has stopped working. Please post an update. I will change my review.
Pleased
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.
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
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.
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.
Very basic
Every time I try and open the calendar on this app it closes the app it is just too basic for me
Great idea but needs location accuracy
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!
Problem
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
Slight problem
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 🇦🇺😀
Nice!
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. 💗🩸
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.
It’s simple and gives you what you want strait away
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
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.
Good app but need to have time zones
Please allow for different time zones to be chosen the dates a wrong and confusing. Thanks so much
Free and does the job so well
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.
doesn’t work
it doesn’t let you set your period end date don’t get this app
Can’t set last period end date.
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.
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!
😘
I love this app
INSTANTLY won’t work
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.
Problem
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?
In app purchase
I really like the app so far! It’s beautiful, minimalist and intuitive. The only thing I didn’t find intuitive was the in app purchase to unlock the other features. I haven’t been able to figure out if it’s a one time or monthly recurring payment. Please make that more clear.
Cute
Got it cuz my sister did.
Confusing
Not sure if just coming from another period tracking app that I’m not use to this one; but it seems to make this bit complicated and it has not predicted my cycle correctly or near the date since I started.
Could be much better
I like how simple it is, but it has different colours indicating different stages of the period but never explains what the colours represent? As someone wanting to learn using the app, with little understanding of the cycle, I feel a bit lost and no more informed! Fine for vaguely tracking but not for learning so much
okay
i like the look of the app but i wish it functioned better :( i try and change the start date and the app crashes, every time i try
Simplicity
I love the simplicity of the app, the color schemes matches perfectly, the app design is pleasing to the eyes. I just hope that they add a note feature.
Purchased, wish I hadn’t.
I just purchased the premium version and the app continues to crash, isn’t saving my logged info correctly and doesn’t seem to save any settings that I submit for notifications.
Try another one.🤷🏻♀️
I give it two stars cuz I like the app and the features it has but crashes too much. I had to restart one time cuz it was crashing and it recently crashed again to the point where I can’t even open the app to put new information.
Just a little more would be helpful
I’m not concerned of prognosticating apps for tracking periods. However the ability to leave notes on a calendar is more necessary. If you could apply such a change it works be appreciated. Love the simplicity and privacy of the app. Thank you.
I would recommend it
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.
Crashed!
I purchased the full app and right after doing that i go to click on the calendar button and the whole thing crashes and doesnt even pull up on the multi menu.
DARK INTERFACE
Only tried this app for a couple minutes before deciding it has a long way to go & it's not for me. The interface isn't as pictured, it's super dark. Black with great text is a bad combination!! Could barely read what I was logging in. I thought maybe I could change it in the settings but there's no option. Also if you choose not to allow notifications, each time that you click the middle icon 'notifications', it automatically shuts down the app. Very inconvenient if you just happen to accidentally touch it. Not for me.
:T
this is the ONLY period app i could find that wasn't nauseatingly bright or had motivational quotes like "yOu gO gUrl XOXOXO🤪🤪❤️❤️" it's really efficient and simple- i really like it, but it keeps crashing on my phone? idk i really like the app but maybe it's to big for my phone.
Crashes
Just paid for it and can’t even use the calendar? It crashes every time. You need to fix this.
Cannot Read anything
Just downloaded the app. The interface is black text on near to black background and it’s near to impossible to read
DONT GET!!
Great concept but SUPER glitchy and crashes all the time. Please don’t waste your time with this app. Try again
alright
can this app let me actually type in notes please and thank you but i love the simplicity of it, i just wish i can type in notes as well.
