  • Great App, use it all the time!

    By DaSuss
    Really cool and helpful.
  • Extremely Convenient

    By Sissy Burgener
    I have been using CardStar for years and absolutely LOVE it!! I no longer have to carry 20+ rewards cards around on a key chain as I placed all of my cards in my CardStar app as well as any notes corresponding to that card. I also included other types of memberships and it's (my) numeric membership number so I would have record of it when needed. This app is oh so convenient and since I take my phone everywhere then of course I have all of my cards everywhere I frequent as well. It's an awesome shopping tool to have! I definitely recommend this app to anyone who loves retail and service rewards programs without the hassle of having to bring along al of those keychain rewards cards. CardStar receives an affirmative 5 star rating from me!!
  • Love the App, BUT

    By judyindaskyz17
    I'd sure love it more if the cards could be in ALPHABETIC ORDER! It would make it so much easier to find them on the spot.

    Trying to send cards but app keeps crashing Never mind- I was sharing them incorrectly
  • Adding notes

    By Cantbee
    I was able to write notes to add information to particular card. Now when I do it won't save it
  • What can't cards be sorted anymore?

    By Huar Yu
    Why is that cards cannot be sorted anymore according to preference? Your app used to include this simple feature but now it doesn't appear to exist anymore. As such it deserves less than two stars until this obvious user functionality is restored.
  • No longer my favorite app

    By BP mobile
    Moved to the cloud and all the pics are gone. No pics of cards makes this a lot less valuable for me.
  • Avoid

    By Elanman 55
    After all your accounts are entered they block your account until you provide all your personal information so they can track your shopping habits.
  • Lost most of my data

    By Dash livid
    It worked great for a few years until today when I opened it to find more than half the cards missing.
