TCG Vault VS Diffee

TCG Vault's answer

• Two markets, never converted: each card is priced from TCGplayer in USD and from Cardmarket in EUR, each from its own market, plus Japanese prints in yen from Yuyu-tei.
• 12 games in one app: Pokémon, Magic, Yu-Gi-Oh!, One Piece, Lorcana, Riftbound, Gundam, Digimon, Flesh and Blood, Star Wars: Unlimited, Union Arena and Grand Archive.
• Scan to price in one step: point the camera at a card and get its name, set, number and current market price.
• Collections with a running total value, a wishlist, price alerts and an Apple Watch app.

TCG Vault's answer

Most scanner apps cover one or two games and quote a single US price. TCG Vault covers 12 games and shows the price where you actually trade: TCGplayer for US collectors, Cardmarket for European collectors, Yuyu-tei for Japanese prints. The free plan includes 3 scans a day, so you can try it on your own cards before paying.

TCG Vault's answer

Trading card collectors and players who want to know what their cards are worth: Pokémon collectors checking pulls and binders, Magic and Yu-Gi-Oh! players valuing their collection, and people who play several games and want one app for all of them. Many of our users are outside the US, especially in Europe, where Cardmarket prices matter more than TCGplayer.

TCG Vault's answer

TCG Vault is made by Appcellent, a small app studio in Bursa, Turkey. It started because checking card prices meant typing card names into search boxes one at a time. We wanted to point a phone at a card and see what it's worth, in the market the collector actually uses, without converting a dollar price into euro. It launched in February 2026 and version 2.0 added iPad, Apple Watch, a wishlist and price alerts.
