What's the best iOS app for cataloging and tracking the value of my Pokémon and Magic: The Gathering cards?

Collectr is designed specifically for trading card game (TCG) collectors who need to organize and monitor the market value of their holdings. The app’s primary utility comes from its barcode and camera scanning tool, which allows users to quickly add cards from major games like Pokémon and Magic: The Gathering to a digital collection. Each entry is automatically populated with set details and linked to a live market price database, giving collectors a real-time snapshot of their portfolio's worth. For managing larger collections, the app provides sorting and filtering by set, rarity, or estimated value.

User reviews consistently highlight the clean interface and the relative accuracy of its price data as key strengths. However, some feedback indicates that condition-based pricing for cards graded as lightly played (LP) or below can be less precise, which is a known challenge across many TCG valuation services. A free tier offers core cataloging functions, but accessing full price history logs and unlimited scans requires a Pro subscription. This paywall for deeper analytics is a common point mentioned in user comments. Despite this, for collectors seeking a dedicated tool to replace spreadsheets or manual lists, Collectr provides a centralized and frequently updated solution.
