SCAM!
Payed $12.99 for a monthly and they took $51.99 out of my bank. Disputing it definitely but want as many people to know they are scamming. Also rating they scan same exact card in a lot of these reviews and people are getting different grades. Hope many people see this review.
Great if you don’t have eyes
Graded 1 card came out differently each told me centering was a 9 even though I know the centering is good. It’s great if you are blind.
Not accurate when grading
Very inaccurate grading. It doesn’t even work when scanning all older cards it can’t find them. Do not recommend paying for this app. It’s not it.
False equivalence
False information for psa pricing and shows the wrong pictures of the cards I scan
Don’t know the cards design
So Rosa’s Encouragement #123 POR, the banner at the top is split down the middle between the words “supporter” and “trainer. The app only gave the surface a 5 saying it was damage. THAT IS THE DESIGN!
Sad
Sadly, you have to pay for more scans.
Lame
Won’t even let you try it out before you buy it. You have to pay to use it. Deleted the app.
Buns
Why do i have to pay to get an ai grading so stupid
Annoying
Constantly saying card not found on high value cards when I scan them.
DONT GET
Genuinely gets in my nerves how you can only scan like 30 cards before paying to scan more(grading also costs money) also can’t grade most your cards cause it won’t show up when searching for it also about 80-90% of the time gets the card I scanned wrong and doesn’t change the card when I re scan also it keeps adding these random cards to my collection that I don’t have and didn’t scan or add.
Waste of money
App is absolute garbage. Costs money to try AI grading then never works. Tried multiple times and it kept saying error. Don’t waste your time or money on this
Pro
I saw so many ads and i thought “hey ill get this app to ai grade my cards” oh no! i need to spend 12$ a month to do so!
Price
Showed in app that there was a discounted first year subscription for under $3 (normally $30 something) ended up immediately getting charged $46.97! Absolutely insane. Charged me $10 more than the normal price. Sent email for refund.
You gotta pay to use the app
You gotta pay to scan unlimited amounts of cards 😭
Ai grading is terrible
The ai grading is so incredibly inaccurate. I scanned over 30 cards and every single one was a 9. Every one. Even some I purposely picked that were very clearly off center or titled, and even scanning some of my PSA 10 slabs, or even cards that were damaged, all the way to pack fresh. So if you’re getting this app for the ai grading function it definitely is not worth the purchase.
This is so bad
They basically force you to buy the upgraded version just to use it! Don’t buy this app!
Grading sucks
Have to pay for the grading🤦♂️
It’s trash don’t buy
Just bought this and when trying a grade a card it asks you what condition it is in. After you make selection it won’t let you scroll down anymore to start the grading process. It’s a junk app avoid
Customer service
Trash customer service. Reached out to them, never heard back. Don’t know why they rated so high when app cant even locate of identity any of the cards.
Awful
This app won’t let you import current collections you have nor will it export them… absolutely trash.
Scam
You have to pay to grade which it never says and was the only reason I got the app
Why do I need to pay for ai grade
The title says it all, this is insane. I hate how the app says to pay for the ai grades
But the ads don’t mention nothing about it
But the ads don’t mention nothing about it
Dont waste your money
Completely unreliable scanned the same card twice 8.5 the got a 9.4 same with other cards ai just aint there yet
Your only going to get 9s
Graded 3 of my CGC Gem Mint 10s with this and they all received a 9 lol. Will be deleting this app you can tell by the naked eye that it’s better than 9s.. Had this app for about 1 hour..
Not free grading
Ads make it seem free but it’s not.
Grading features behind paywall
The only reason I wanted to try this app was to see what it would grade some of my higher end cards at, but that feature is locked behind a (currently priced at a yearly fee of $35 but that was a 60% discount price) paywall. The “free” features of this app are literally just a pricing guide that honestly is outdated by what feels like a week or longer (which is a long time in card pricing) they don’t have sets that have come out within the last two months. The “free” features won’t let you check the price difference between first edition and unlimited which can be substantial for some cards. Also in order to filter a card based on its rarity you will have to pay for that as well. I would be more willing to try a membership if they gave me a chance to use the feature but given the rest of the app I don’t want to pay for an app that uses outdated information. The app doesn’t show all rarity versions of a card within one set only the cheapest option was shown so if you happened to have the $300 copy of the card it will show the $60 version as if it was the same thing.
Subscription Required
Can only add 35 cards by scan without paying a subscription. Cannot ai grade at all without subscription. Joke of an app.
This app doesn’t calculate centering well at all!!!
You are better off buying a centering tool! Don’t waste money on this app!!
Doesn’t even tell me if his PSA 10 or not, and it brings up different cards
And doesn’t work how it said on the commercial I would definitely not get this app. It’s a scammer in my opinion.
Why not unlimited scans?
So you guys should definitely add a feature where, okay not unlimited scans but at least like 20 a day or something not 35 forever
Doesn’t even work
Paid for the grading ai tried for over an hour just to get one card to grade and just kept getting “something went wrong, try again” error, waste of money
Could be so much better
I got this as my first choice app to scan all my cards only for the camera to be blurry even in good lighting and clean phone lens. Also I edit and save my cards in the moment only for my cards to change to holo having me go one by one to fix each one.. needed to completely delete and restart app and using now it’s not any better. Very dissatisfied and might cancel my subscription
Honest review
Looked very good at the start and stated that it costed no money at all but to even start the app you have to pay money
Cancel the charges please I’m not paying for them and it keep trying to charge me

Inconsistent AI grading and not free to try out.
Wanted to try this “AI Grading” everyone is talking about online and saw this app advertised on a YouTube video. Not very impressed. The AI Grading in this app was not free to try and required you to sign up for a monthly or annual membership. I chose just the monthly membership for $7.99 to try out the software. I have a Mega Charizard X EX #125 SIR from Phantasmal Flames I want to get graded. After using the AI grading App twice on the same card, it gave 2 different grades (first one an 8.5 and the second one a 9) with completely different reasoning for both grade reports. Pictures were taken on the same dark colored background using natural light. The grade reports gave different information for the rear centering and the rear edges of the card. One grade report said the edges showed whitening on the top edge whereas the other grade report said it was very sharp and clean. One grade report said that the rear centering was off center to the top and right and the other grade report said the rear centering was off center to the bottom and right. Even when you measure the rear centering with an actual centering tool it is within the 55/45 split specification but the AI Grading report rated it an 8.5. Will not continue the membership and highly discourage people from wasting their money on this gimmick of an app.
AI grading super inconsistent
I like this app for the most part but the main problem is the AI grading for one it’s $7.99 to even use the feature that would be fine. If not for being super inconsistent I used it today to grade a one piece, uta alt art from eb03 and when I used this app to AI graded at GameStop with great lighting it gave the card a 9.7 then when I got home, I tried it again and the AI gave it a flat 9 grade. So I decided to grade it again so I put it on my bed and graded it and behold the card got a 9.5 grade. I did it one more time on my nightstand right under my light. And yet again, I’m getting 9. I wish the AI was better and more consistent because right now I feel that it’s definitely not worth the 7.99 price tag Every month. Especially when I’m submitting cards for $25 each based on the grades from this app
Ai grading sucks
Good luck getting the AI grading to work. EVERY SINGLE SCAN, it says to “retry” and when you retry it says there was a problem. I’ve only scanned 10 card and I had to fight tooth and nail just to get them to work. Absolutely canceling my membership, which by the way. Before you download. It costs $35/year for the AI grading.
Hiding basic features behind paywall
I downloaded this app because i cannot stand the collectr apps horrendous UI… after about 5 minutes i deleted this app… they hide the most basic features behind their paywall so you become a pro member… i couldnt sort by cards i dont have or just filter specific type of cards without becoming a pro member. The pure greed to make that kind of decision… will look at another app to track my cards
Not worth the time
You would think the app would give you 2 or 3 free scans of the AI grading just so you know what the expect. Nope. Locked behind a monthly subscription - not worth the time and money for something you don’t even know what to expect in quality. If you’re looking for something to track your collection or get pricing from, use CollectR which is free.
Dumb
Why do I need to pay for a membership just to see what the ai grading would be.
Honest review
From what I saw, you could see the condition and grade it would estimate. Only lets you scan.
Disappointed
I just paid for the app and when I select AI GRADING it freezes and I have to exit the app and restart it everytime. It doesn’t even let me get to scan a card, I click ai grading, a loading wheel pops up and immediately freezes the whole app
Don’t download this app
Tried using the AI scan and it was absolute garbage. Feels like I was robbed of 7.99
Not useable!
Just downloaded it and it’s not useable. I created an account, just for it to log me out immediately and make me reset my password, which then gave me an error when I entered the code from the email. Cool. Tried creating a whole new account, but got an error doing that too so I quite literally cannot use this app
Nothing is frww
The ads make it seem like the ai grading system is free it is not and you can only add a set amount of cards a day such a lame thing to lock behind a paywall
Bro
Got this app to check a grade, have to pay, also tired to scan a card didn’t scan after 20 minutes deleted this app
DO NOT BUY FOR ONE PIECE
This app is TERRIBLE for one piece. It is missing I’d say about 90% of the cards that exist in English. ZERO recognition of alternative languages. Half the alt arts aren’t in the system. This is just a really worthless app. 0/5 stars
Ai is wrong and camera sucks
The camera sucks, it doesn't focus properly. Also for sum reason there limited scans and I'm NOT paying for pro. I scanned my base set pikachu with 50 HP and with a red name, it gave me a random chunk a chu with 40 HP and a black name and said it was 3.58. The ai might be good at searching prices but please insted of spending money on adds saying how good and accurate it is just fix your app and focus on peoples happiness and when it's good start making the adds.
Trash
Paid for a year and now can’t log in
Don’t bother.
The app can barely identify any of my photos I take. The ones it does register can’t even match the correct card. It can’t handle this and yet I’m suppose to believe it can accurately grade a card. Waste of my time downloading this.
