### 3/5 — Mediocre app, terrible analytics

*2026-08-05*

There are a few reasons I’m writing this review today. First, the apps market value can be off of TCG by a large margin. I’ve lost hundreds sticking to double holo pricing instead of just using TCGplayer. I wanted the easiness of a scan and inventory type of deal but essentially I’m scamming myself using the feature I payed $60 for the year for.
Another reason, I hate advertisements in my email. When you give them your email - they will send you ads for arena club and other companies, mind you I’m a premium user because I didn’t cancel in time. This is ridiculous and incredibly incredulous. I unsubscribed from their emails and just plan on taking the $60 L here and move on.
I love the idea of the app, and I’m aware the pricing comes from various forms such as eBay too. I’m just not a fan, and I’m sure there are others with similar qualms.

### 5/5 — Best app for card vendors and collectors

*2026-07-16, version 1.16*

I definitely recommend this app if you are a seller or if you just like to keep up with ur collection on what to hold and what to sell

### 5/5 — Great app and accurate

*2026-07-15*

Great app and the vendor mode even though it’s in beta is really useful!

### 1/5 — Bad customer service

*2026-07-15*

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.

### 5/5 — Double holo

*2026-07-13*

Amazing card app and easy to navigate

### 1/5 — I’ve never seen anything like this

*2026-07-11*

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.

### 5/5 — AWESOME APP

*2026-07-05, version 1.15*

Great app! Needs to have a faster update when new sets come out.

### 2/5 — Nahhh

*2026-07-02, version 1.15*

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

### 1/5 — Frozen APP

*2026-06-24, version 1.14*

At least user test before launching…

### 1/5 — Faulty

*2026-06-21, version 1.14*

Page just stays frozen
