Once Customer Insights

1. Good app 👍✨Needs terms, conditions and ads in native language to be of use... I will wait & see if this gets fixed, but til then, "My Calendar" is a good free app I have used for years with no issues -at different levels & with different aims-ie track period, learn natural fertility for conception or contraceptive use & it's very customizable, so I would stick with it, apart from my not liking their pink background & , which is the main reason I still periodically try out other period apps like this one.I started seeing a Chinese blue button like an ad but i was able to close it no problem.

2. It's impossible to use anymore.I absolutely love this app and have been using it for quite some time but for the last month I'm not receiving my birth control pill reminder/notification on my phone... I checked if it's still on and it says it is, I have also tried turning it on and off a couple of times but it still doesn't remind me to take the pill so I might have to find a different app if this continues.This app allows me to track my period, record my symptoms any day of the week.

3. Used to love this app, but when I switched phones I noticed it was showing a lot of non-English ads (possibly in Korean or Mandarin).

4. It says there's a network connection issue (there isn't).I love it.

5. Play Store definitely needs to investigate this!I've used this app for years, & keep coming back to it for its ease & convenience.

6. You can record when you have sex and if shows a little "love heart" in the calendar.

7. It's so simple and I never lost my data for this 2 years.

8. However, I was forced to purchase a new device when my old device started green screening a few days ago.

9. I've switched multiple devices in the past with no issue & as always I backed up my info prior to the switch.

10. Sure enough, my phone stopped acting glitchy.

11. Plus, my brand new phone was acting oddly glitchy.
