Persian Calendar Customer Insights

1. Day calendar freez until you open the appThis app is so sharp and good to have the compelete calendar right on your phone! But my problem is that the calendar notification doesn't follow the date and keeps stoping on a day, so I have to open the app and close it to fix the notification.

2. My only nitpick is not having the option for changing the holidays color in the 4x3 widget; as of now, I guess the app has chosen a color based on my wallpaper which doesn't provide enough contrast with the color I have chosen for the regular days.

3. It's odd!Well I used to like it until the last update! I don't know why but the date doesn't sync with the notification bar and it caused some mistakes for me as I check it regularly to manage my routines.

4. Other than this, everything is fine.It is a good calendar, although it is simple, this simplicity makes it attractivethe app is perfect and also comes with 2mgb updates every week that improve a lot of things not just some random stuffI used to have it for a long time.

5. But recently, it doesn't work in the background correctly, and I need to open the app to show the correct date.

6. It seems it's a technical issue with the "work manager" library!It was good until today but today it shows tomorrow's date and day, one day ahead of the correct date and timeNot good.

7. It's so annoying please fix this problem.Great app, but for the last couple of weeks, the day doesn't change automatically.

8. For example this morning it's still showing me yesterday's info in the notification bar and I have to open the app for it to update the notification.

9. Its easy to use, all optional changes are easily available, user friendly environment, and for those who do not live in Iran, the widget would be so useful.

10. Its great for having the praying times infront of you on the widget.

11. I've got to uninstall the application to avoid more mistakes.I'm using this app for 3 years and I like it so much.
