Review summary

Users like OneCollector for easy collection management, missing-item checks, and set/price views, but cite frequent downsides: high subscription/ads, incomplete content (OP12, promos, ST/precon), limited features (no portfolio/deck builder/cross-device sync), and localization/currency issues. Overall a strong tracking tool hampered by content breadth, pricing, and feature gaps.

Pros

Easy to manage your collection and see what’s missing, helping you avoid duplicates.
Organized views by set and rarity make it visually appealing and easy to navigate.
Useful for tracking set lists and prices, aiding purchase decisions.
Helpful for specific card lines (e.g., Japanese One Piece cards) and overall collection management.

Cons

Subscription pricing and ads are a frequent complaint (expensive plans, paywalls).
Key content is missing or not uploaded yet (OP12 and other sets/cards); some cards like Royal Blood aren’t available in all languages.
Limited feature set (no portfolio view, deck builder, store HUD, or cross-device sync; no promo/ST/precon card support).
Currency/localization issues (prices shown in Euros; lack of USD option; language availability limits).
Data completeness and scanning issues (some variants not matched correctly; occasional inaccuracies in card data).

2026-03-09	Pu*****	Was excited to download the app due to the reviews saying it was great in tracking, until i opened it and the first thing that i find out is that they have $30 subscription to do simple things. Terrible experience, deleted after 2 minutes

2025-08-28	Lo*****	I’ve only had the app for just a bit of today, but so far it’s going well! Is there any schedule of when OP12 will be added? That’s where a bulk of my cards are from and I can’t add them yet lol. Oh and there are three cards that won’t show up for some reason. OP07-113, OP07-109, and OP09-034. There are others with that number but the art is different?

2025-06-14	On*****	I really like this app for Japanese one piece cards. It took me awhile to learn how to use it. I am wondering when you’ll upload OP12 😅

2025-05-09	Th*****	I love this app! The only change that I would make is updating the search function to include alt arts.

2025-02-04	AG*****	As a card collector it makes it easy to manage all my cards and see what’s missing if I stumble upon a card in the wild. Has helped prevent me from buying duplicates I didn’t need

2024-10-16	To*****	This app is the best I’ve seen for keeping track of my collection. A couple things I’d like to see in the future would be to have the option to see the card values in different currencies, also there’s no way to add promo cards, that would be kool to have.

2024-09-29	#d*****	While this may be a newer app, for this review I am going to be comparing this App to what I believe to be its biggest competitor Collectr Pros: 1) unlimited use of the scan function. When using CollectR you have to pay for the pro version after 25 scans. 2) having a place where you can view cards organized by set and rarity is a nice touch, that’s aesthetically pleasing. 3) the price is much better at 9.99/year Vs. 7.99/month 4) card information seems accurate enough Cons: 1) doesn’t have the ability to add any ST or precon cards. This is a bigger deal than you might think, as some of the ST SR cards are worth a few dollars which makes them substantially more valuable than a lot of commons or uncommon. Most ST SRs only have 2 available in a precon so it’s not unusual for people to buy multiple of the same precon. Meaning a long term collector will have quite a few nicer cards they can’t track 2) no portfolio view. This is HUGE. Without this view people can’t easily organize or view their cards based on rarity or value. Furthermore the whole point of a collector app is to track the value of your cards as time progresses. Currently there is no easy way (as far as I’m aware) to manage and view the value of your entire collection. It would also be inaccurate without the ST cards available. If these two cons were addressed I could easily see me using this app over CollectR and even paying for the add free version. For now I’m going to wait on uploading my collection to either in hopes this app improves 3) no store HUD. While this may not be the most important option. It’s very nice to have an integrated HUD that shows you what cards are currently being auctioned for, and can even link you to where you can buy said cards. While this isn’t the mostly necessary feature purely for collecting it does help the user with ease of access and information. 4) no deck builder. While not everybody who uses your app will want or use this function. It makes it easier to compare and view your cards when trying to assemble a deck for tournaments or anything else. 5) the least important but still notable is that this app only tracks one piece cards whereas collectR can track all your cards across multiple TCGs. While this can get in your way if you only play OPTCG. If you play others this feature is valuable. As somebody transitioning away from other TCGs this is the least important to me. 6) prices are in Euros and not dollars. While I understand this is more convenient for many people, a USD option would be nice. I’m new to the app so it’s possible I’m missing that view, from a menu I haven’t explored enough. Some other things I’ve noticed is that when you scan a card. It might just be looking for the OP number on the bottom right. I scanned in my secret rare Uta (version 3) from OP2 but it suggested the Version one. Which wasn’t a big deal because the version 3 was the second recommended option. But I found it interesting enough to note. If these changes get addressed please feel to reach out and i will happily amend my score / review.
