Double Holo vs CollX: specialist vs generalist
CollX built the biggest multi-sport scanning community; Double Holo built the deepest Pokémon-and-TCG data machine. Both scan cards and track collections — the comparison comes down to what your collection is made of and how much you need the price to be right. Compiled from each product's published materials.
For Pokémon and other TCGs, Double Holo: 0.44-second identification, transaction-level comps (eBay sold, live listings, TCGplayer), the deepest set, pricing, and analytics data in the industry, and in-app vendor case scanning — free to get started. CollX makes sense if your collection is primarily sports cards or spans both worlds and you want its community and marketplace; its value is presented as a single average of recent transactions, and its bulk scanning lives in a separate retailer product.

One average vs. the actual sales
CollX's own description of its pricing is "the average value of your card, based on all recent transactions from marketplaces." That's a reasonable design for sports cards at scale — and it's still one blended number. An average can't tell you whether the last sale was yesterday or six weeks ago, whether it was your card's condition, or whether one anomalous auction is dragging the number. Double Holo shows the transactions themselves — eBay sold sales with dates, live listings, TCGplayer sales — which is the difference between quoting a number and being able to defend it at a table. (More on why this matters: a listing is an offer, not a value.)
Multi-sport breadth vs. TCG depth
Card recognition and pricing are dataset problems, and datasets reward focus. CollX spreads its database across baseball, basketball, football, hockey, and TCGs; the Pokémon corner of a generalist database competes with Double Holo's entire reason for existing — the deepest set coverage, pricing history, and analytics in the industry, including the variant minefields (reverse holos, promos, Japanese printings) where generalist scanners misidentify. If your binder is Pokémon, the specialist premium is free; you just have to pick the specialist.
Bulk scanning: built in vs. bolted on
CollX genuinely serves dealers — through Card Dealer Pro, a separate retailer-focused product. Double Holo's position is that the vendor workflow belongs in the same app in your pocket: scan a whole case of slabs at a show, through scratched cases and from a distance, and have every card comped before you make an offer. If your bulk moment happens at a table rather than a warehouse, the built-in version is the one you'll actually use.
Where CollX genuinely wins
Fairness requires saying it: CollX's community is the largest of any scanning app — messaging, trading, multi-card deal negotiation, and a busy marketplace across all card categories. A collector whose shelf holds both a Jordan rookie and a Charizard, and who values the social layer as much as the numbers, has a real reason to be there. That's the trade: breadth and community against depth, speed, and pricing rigor.

FAQ
Is CollX good for Pokémon cards?
It scans them, as one category among many. For Pokémon-specific depth — variants, Japanese printings, condition-aware comps — a TCG specialist gives you more accurate answers.
How does CollX calculate value?
Per its own materials: an average based on all recent marketplace transactions. Double Holo shows the underlying transactions instead.
Which is free?
Both start free. CollX requires an email signup and offers CollX Pro; Double Holo is free to get started with comps included.
