Store ratings include star-only taps from in-app prompts, which skew high. The peak and recent figures come only from people who wrote a review, which skews low. Compare each against itself: the drop is the signal, and a big gap between the two usually means heavy rating prompting is masking unhappy users.

No longer truly free

★ · v1.19 · Oct 9, 2026

When I first started on this app, there was no limit on the amount of items to add so I used this app as inventory. Now I have over 300 items in my inventory with now a sudden paywall, where I can no longer add items over the count of 50. So know my account is bricked unless I sign up for a plan to continue using the app.

GREED, GREED, GREED!!

★ · v1.19 · Oct 9, 2026

What a great app this WAS for vendors. I didn’t mind paying the premium service however they just launched their new Vendor premium service that is separate from their premium app service, with the lowest tier costing $200 and highest tier at $800. That want you to pay to add cards in the app which Collectr and other apps already let you do for FREE. They had a chance to change the game and still make money but greed is going to hit them as this market is cooling off. I can’t wait to share this with all of my vendor friends and my YouTube audience.

Money grab

★ · v1.19 · Oct 7, 2026

Seems like they’re just out to squeeze the hobby for every dollar they can. Scanner doesn’t work well and every feature you could want is behind another pay wall

Borderline bloatware account creation

★ · v1.19 · Oct 4, 2026

Account creation is atrocious has about 50 pages to get click through

Setup of app Sucks

★ · v1.18 · Oct 1, 2026

Takes way to long to setup and way to many questions and to much of a run around. I like simplicity.

BORING

★★ · v1.18 · Sep 21, 2026

Your onboard process is way too long…. It’s asking questions that’s irrelevant and I just want to skip and get directly into the app…. Long pointless process. Remove it or give option to skip.

Bad customer service

★ · v1.15 · Jul 15, 2026

I’ve been trying to get help with a subscription issue for over a week now. I’ve sent emails and I’ve opened tickets on their site. Really frustrating. I’m bummed because of how many creators I like that they work with.

I’ve never seen anything like this

★ · v1.15 · Jul 11, 2026

The fact that I’ve never seen anything like this and you keep asking me for money before I’ve ever even used it. I’m not gonna spend money on your app. To me it just seems like another scam.

Nahhh

★★ · v1.15 · Jul 2, 2026

Too much personal info required to create an account when collectr exists.

Frozen APP

★ · v1.14 · Jun 24, 2026

At least user test before launching…

Faulty

★ · v1.14 · Jun 21, 2026

Page just stays frozen

2 Factor is Broken

★ · v1.9 · May 15, 2026

Can’t even login to this app. 2 factor authentication doesn’t work.

Need ui fixes

★ · v1.7 · Apr 29, 2026

Can’t even make an account trying to auto fill/create my password and it won’t pull up a keyboard after it filled and wouldn’t take password said I needed to add special character and won’t let me type

Fake inventory from multiple sellers

★ · v1.7 · Apr 28, 2026

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

Overhyped?

★ · v1.6 · Apr 25, 2026

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

★ · v1.6 · Apr 24, 2026

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

Sign up process

★ · v1.4 · Apr 7, 2026

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

Terrible sign up process

★ · v1.1 · Mar 17, 2026

Signing up is terrible process keeps saying my email or password is invalid and the signup link doesn’t work would not recommend stick to TCG at least that’s easy to understand

The opportunity

What would it take to build a viable competitor, what would it cost to run every month, and a prompt to get started. Generated from the reviews on file; one LLM call per brief. Set ANTHROPIC_API_KEY for a real brief; the stub only fills in a template.
