    Great app but not for the super high monthly fee.

  • Fake inventory from multiple sellers

    Doubleholo doesn’t care. I’ve received multiple canceled orders now. If you want to actually receive what you ordered then good luck.

  • Overhyped?

    Idk if these glowing reviews are paid or what - but this app is super glitchy. I had really high hopes for the scanning feature but half the time it can’t even focus properly when you do what the app tells you by filling the cert scan box on the screen- you actually have to hold the slab further back for it to even focus. This was the biggie for me but the whole thing feels like some shaky vibe-coded experiment. Most annoyingly, I had to go through the trouble of creating an account and sharing a phone number just to kick the tires and try scanning. Seems more like a user info grab app more than anything else. Uninstalling for now- provides zero value to me beyond what price charting, ebay, and the psa app already do better, for free! Good luck! This does not hold up to the hype.

  • Not worth your time

    After seeing ads for a month straight I finally decided to check it out just to find out it’s minimum $15 a month to use any feature mentioned in said ads

  • Good start

    I have been using this app for the last couple of days and I think there’s a lot of potential here. Several glitches going through the UI I think you guys need to add a story so that when someone clicks in the cart they should be able to select the seller, i can’t. Same with return buttons, they don’t work when I navigate for some parts like in the cart or click on more details, please contact me if you want to suggestions for new features.

  • Fun Concept with Big Potential for Serious Collectors

    As a collector who follows market values and trends closely, I really like what Double Holo is building. The concept is fun, engaging, and captures that same excitement you get from opening packs or chasing cards. The app is clean and easy to use, and it’s great for both casual and newer collectors. That said, adding more market data (recent sales, trends, or grading context) would take it to the next level and make it even more valuable for serious collectors. Overall, strong concept with a lot of potential.

  • Sign up process

    The app looks cool but I can’t even get in. The sign-up is broken AF—keeps erroring out on my username. It tells me to add a character, then tells me not to. Super frustrating. Please fix the registration proc

  • Innovative to say the least

    It’s a new app and yes a little buggy at times but so far it’s really solid what they have going and I expect it to only improve from here

  • some ideas to make the app better -

    By Macy Zimmerman
    app is cool in theory, would love an option to save cards from our own personal collection on the app so we can see the value of our cards to help determine if we would prefer to sell them based on what they’re worth. i don’t like that the only option is to list them for sale. i dont always want to sell my cards but if a card in my collection turns out to be worth something, i would like to know without it automatically be listed for sale right off the bat. hope this makes sense!

  • Terrible sign up process
