Synchronize

I’ve used this app for years and for the past one it hasn’t synchronized once to my Google acct and is now stating that my personal information will be deleted. Such an unfortunate thing to happen on this app that I use monthly to track my cycle. Please figure out the synchronize feature and lack of updating. User since 2017.

Have to Watch an Ad Just to Record Data

It's incredibly annoying. I'm just going to remove the download and find another app or manually record my dates now because it's ridiculous that I have to watch a 30 second ad just to record my period.

Bug problems

I usually love this app. But here lately I’ve been having issues with the app. It closes automatically or doesn’t put when I end. It tries to override what I save. I can’t even open the app now. It keeps closing on its own. I tried to write to the app support but it’s not letting me. App itself closes real fast before I can take a screenshot of my period tracker dates. I even had issues looking for the app on App Store. When usually I can find it fast with no issues. I would at least like to screenshot my menstrual cycles so I can get a different app. Very disappointed because this app was my favorite one. Now I have to try out new ones.

Response from developer

안녕하세요. 원스입니다. 서비스 이용에 불편을 드려 죄송합니다.현재 개발팀에서 문제 파악중에 있습니다. 혹시 사용하시는 os가 최신버전이실까요? 앱 삭제를 하지않고 os버전 업데이트 요청드리며 그 이후에도 해결이 되지 않는다면, once@malang.kr를 통해 계정, 기기정보, os버전을 포함해 다시한번 재문의 부탁드립니다. 감사합니다.

The app stay open

I’ve been using this app for few years now. But today when I tried to open it the app just shuts down. I’ve tried several times but the same thing happens. Can you help?

App Not Working

The app used to work great but now closes automatically every time I try to open it. Wont stay open for even a fraction of a second.

Ovulation

It is the 3rd time that I have uninstalled it and reinstalled the app, because the normal thing is that when I mark my first day of period, the calendar automatically marks my approximate days of ovulation, and the app has a defect in that it does not. When I mark my first day of menstruation, it marks the past days of ovulation, I need the future not the past to show me.

Ads ads ads

Great app but I’ve never understood why a period tracker has ads. Also many of these ads aren’t in English. I dont want to spend extra time when I’m just trying to track so searching for an alternative, only downside is i cant export this data

It won’t let me login back in

I can’t log back into my account and it’s not even sending a password reset email to my account

The ads are starting to get excessive! Please stop
