## Most critical reviews (10 lowest-rated)

### 1/5 — Instant Paywall

*2025-08-17*

Steps: Load app, sign up, hit instantaneous paywall of 5 cards for $9.99/mo, 25 cards $49.99/mo etc etc.  (No trial of a couple cards to see the product work), last step….delete app. What a missed opportunity to show an interested party how app actually works.

### 1/5 — Pricing and user interface are not great

*2025-07-30*

Not worth the price they’re asking for the service. User interface is really clunky and not worth the time to try to navigate. Try another service before even getting started on this one.

### 1/5 — Scammed !!!

*2024-07-16*

I subscribed to a plan which auto-renewed but my card count didn’t increase !!! I’ve emailed a couple times and now getting no response … I’ve essentially been scammed .. stay away from this app

**Developer response:** We were able to correct this issue for you.  If there is another issue or ongoing concern please email us at team@cardboss.com.  Please remove or adjust this review.

### 1/5 — What a joke

*2024-01-10*

Website still has 2022 copyright, new member 1 free card redeem on app doesn’t work, and many links on the website are broken because they didn’t pay the bill on their QR code URL shortener service. So sad, I was looking forward to this app.

**Developer response:** We have removed the one card free option because “customers” were gaming the system and grading countless free cards.  That said, we listened to customer feedback and have an entry level subscription that is $9.99/month that can be cancelled anytime.  Please give us a try.

### 2/5 — Continue to have issues

*2026-01-26*

Every month my account charges me for the app. But my card counter doesn’t increase. This has happened several months in a row.  So often I barely use the app anymore. And it takes several hours before I am notified that the grade has come in. I like the system but still continue to have issues. I think this is my last month.

### 2/5 — They want money before you even get a chance to see if this service works.

*2025-04-12*

So this service might be great, And I might pay for it but jeez. You have to spend a minimum of $10 just to use the service. WITHOUT knowing how good it is. Give people who sign up like 2 free cards or something to get looked at so there is a WANT to give you my money.

### 5/5 — Great APP

*2026-05-27*

This app has worked amazing saved me a bunch of money on cards i would have sent in and also for cards I was not sure of. Customer service if there is any issues is amazing and fast someone reached out to me and offered me a mat that helps you when grading cards never seen such great customer service. For sure now when it seems like it gone everywhere else. LOVE THIS APP will let everyone know in the card game.

### 5/5 — Card boss is a game changer

*2026-03-17*

Love this app, it has been a huge help in my PSA ratios .. highly recommend!!

### 5/5 — A game changer for the hobby!!

*2023-09-22*

We have been using Card Boss for a while now and we strongly feel at 828_cards that this app is a game changer for the hobby. If you grade cards, this is a MUST use app first. We have pre-graded over 100 cards and sent many off for grading by PSA and SGC. We’ve had a 96% success rate using Card Boss. 

Gone are the days sending and paying for a 7 or 8 and getting that grade back and the card being more valuable raw. We can see the pre-grades of a 9 or a 10 and invest in the grading process and 4x our money of some cards. 

This is why this is a game changer for the hobby and for us!!

### 5/5 — Fast and Easy

*2023-07-26*

Submitted a card and received a grade in under an hour. Definitely using this as a pre-grading tool!
