Cardstar app will not open since my upgrade to ios 13.1.1

Cool it works, I was able to take screenshots of all of them to find another app but also if you a device running iOS 12... you can log in and see your cards too! Any recommendations for a similar app?

It appears CardStar hasn't been updated for almost a year, but you should still contact the app's developer for help:

CardStar and Express Checkout Developer

They state for help with CardStar, one should email support@cardstar.zendesk.com.

I tried the solution outlined below and it didn’t work. But opening the app a second time works. It’s odd to say the least. And you have to go through this convoluted process each time. At least I was able to record all my card numbers. Thanks everyone for your help.

Post by Misty is very helpful

"Close cardstar if it is open in the background (swipe to close)

After you select Clear Cache click on the Settings again to go back a screen then try to open CardStar and let me know."

Also Phildengri suggestion of just screen shots of each was good..then you'll have to input manually

Neither is mine! I have used it for years without problem, don’t even have my cards! One I scanned them into the app I tossed them away. Totally lost now and have tried every fix listed without success! 😟

CardStar just did an upgrade this week and now it works fine. However I already transferred to StoCard and will probably stick there. Much higher rating with quite a few reviews and good ratings from the geek magazines

just tried that & no luck, do I have to restart my iPhone?

I have the same problem I tried deleting and reinstalling a few times no luck it works for a bit then nothing does not open !

Seems there’s a lot of us with the same problem

Im having the same issue with my CardStar app. I use it alot especially at cvs it saves me money. Hope this get resolved quickly

I even upgraded to 13.1.2, still not working Hope there's a fix!

Go into settings and clear cache then the app will open. have to do each time.

I have & they never responded. Check out Stocard or mobile-pocket
