### 3/5 — Glitchy

*2026-07-31, version 3.249*

I love this app, it is so easy to use. I have the pro version, and the most up to date iOS version, but whenever I want to go look at previous years it’s glitchy and not aligned to the center of the phone it shows up on a quarter of my screen. Then if I select a year, it goes to an all white screen and freezes where I have to shut the app down and restart.
Is there something I’m missing?

### 4/5 — Great App

*2026-01-11, version 3.249*

I’ve been using this app for years and it’s been very accurate as to when I would be starting my period. I do wish there was an option to sync my data history with Apple Health.

### 5/5 — Great! But no moon phases option?

*2025-05-15, version 3.249*

I’ve used this app for so many years and I love it. The only thing I think is missing are the moon phases that I would like to keep track of beside my period.

### 3/5 — Loved since the beginning but something happened

*2023-09-18, version 3.249*

I’ve loved this app for as long as it’s been a thing. I hate the newer apps because they aren’t as simplified to me as this one. I don’t want an all girly and baby-like app. I’m not against either things, I just haven’t liked any other app layouts or anything. This app isn’t all about the frills but allows you to make changes. The problem is, within the last month or so I feel as if something has happened to ruin it and I’m just now seeing it. It could be further back since I haven’t played around with things lately but I’ve continued to log my periods and they aren’t there. I have my account set to auto-backup but it seems that it hasn’t done that. When I try to reload, it goes back nearly a year! This is unacceptable. Where’s my info?! As for ads, I don’t have them…just pay for it. It’s worth it.

### 3/5 — Incorrect Notification badge issue all of a sudden

*2023-03-30, version 3.249*

I have the most up to date app and iOS version. I’ve been using this app for at least ten years, no issues. Now suddenly, the notification badge on to app that is supposed to tell me what day in my cycle I’m in is showing +5 days of what the actual cycle day is (which is still accurate within the app on the calendar). Very frustrating, especially if you wanted to use this notification for quick reference to follow natural family planning method guidelines. So disappointed. I filled out a contact form to ask for assistance fixing this bug and got no response.

### 1/5 — Не работают данные о кольце нова ринг

*2023-01-25*

Нова ринг вести в приложении опция есть. Но вести его не получается. Поддержка не отвечает.

**Developer response:** Пожалуйста, напишите нам по адресу service@mydays.club, чтобы мы могли вам помочь.

### 1/5 — Paid for pro? Too bad, now you have to subscribe

*2022-08-27*

I’ve been a loyal user of the app for years. I paid for pro version. 

Recently sleazy ads started popping up. I complained and was told this should happen in the pro version. 

Well now it appears everyone has to subscribe if you want get rid of ads. 

Those who paid for pro previously don’t seem to be grandfathered in. 

If your looking for a period app I’d recommend the old version. Now that’s not available I recommend looking elsewhere  — this app doesn’t offer enough not make this kind of deceptive practice (making payment model change with no warning) acceptable.

**Developer response:** please send an email to androchris@gmail.com to help you. the pro version has no ads, and will install as extra app on ur device.

### 3/5 — Needs to go back to how it was

*2022-07-03, version 3.249*

I been using this app for about 4 years now and now it has taking the features off.

### 2/5 — Don’t pay just use the lite app

*2022-05-10, version 3.249*

I purchased this app because I loved the free version but lost all my info after a phone issue. So I paid for the pro version so I could do the backups. It’s been a few years and no backups. I’ve tried to find a contact or email to try and resolve the issue but I’ve only ended up at a useless blog. I lLOVE the format of this app but I just want to be able to back it up if something goes wrong so I don’t lose years of info. Serious info like miscarriages and missed periods. If someone can help me I will edit my review

### 4/5 — Simple and accurate

*2022-04-26, version 3.249*

Tried all the big name apps and keep coming back to this one. The others are so annoying and distracting. This one has just what I need, no more, no less. It’s extremely accurate with predicting my start date too after a few months’ worth of data entry. Hopefully this app will stay in the App Store!
