  • Beware

    By TerrySouth5
    App forced some kind of upgrade that locked me out. All of my cards have been in this app for years and I cannot find contact number or site to get reset. Just emails that receive no response
  • was great - new version duplicates cards & can't save "notes"

    By simplify my life
    loved this app initially - loaded all my loyalty cards - told all my colleagues about it - it was great. Then awhile back they must've had a version change, because all of a sudden, one day I went to pull up a card, and all my cards were entered twice and when I went in to add some passwords in the "notes" section, there was no way to save the notes. Looking for a replacement app now--
  • Great app!

    Easy to find and add new cards to this app. It is reliable and easy to use. Update: This app has *always* worked for me (I'm an early user of the app). And the best part, most stores are able to scan my 'key card' off this app. The people complaining about having to do extra clicks in the app... waa, waa, waa... quit crying. The app works when similar apps don't in places that scan the screen. 2008 - 2018 Update: May,2018 I dropped a star. The camera doesn’t work on the app. You have to manually input the 16 bazillion numbers. I give the 5 stars back when the camera works again.
  • Very handy. A few gripes.

    On my wife’s iPhone (but NOT on mine) some cards yield a message about an error response from a “Proxy Associate”. After selecting “OK” the appropriate barcode is displayed. (This continues after several months of use.) Not all rewards cards are handled. E.g., Krispy Kreme, for whom we must retain a separate app (which uses a QR code, NOT a bar code), Alberpersons, Panda Express. All in all, mediocre. I’ve sent a message to support but have not heard back yet.
  • Love it! But where is the “nearby cards”!

    By Confusing rating
    It’s a great app. Would like to be able to group cards. Also, my “nearby cards” section disappeared from the home screen and doesn’t appear to be a way to get it back.

    I am new to CardStar and I like the fact that I can carry my cards around digitally, without carrying them.

  • Lost All of my Data

    I have been using this app for a few months now. Today I clicked on it on my phone and all of my data was gone! Nobody will return any of my emails. Do not use!
