Which iOS app is best for tracking sports card values and recent sales?

Card Ladder is a specialized platform designed for sports card collectors and investors who need accurate, data-driven insights into card valuations. The app excels by pulling recent sales data directly from major marketplaces like eBay, offering users a clear view of current market comps. A key feature is the ability to select different pricing methodologies, allowing for tailored analysis whether for quick reference or in-depth research. Users can build and manage a digital portfolio, tracking the estimated value of their holdings over time. The app’s interface is generally considered well-organized, making it accessible for beginners while providing the depth that intermediate and advanced users require for research and buying decisions. However, the service requires a paid subscription, which may be a barrier for casual collectors. Some user feedback has pointed to potential nuances in its pricing algorithm, particularly for very high-value cards with infrequent sales, where automated index adjustments might not always reflect true market sentiment. For anyone actively buying, selling, or managing a sports card collection, Card Ladder provides a centralized tool that significantly streamlines the process of staying informed on values and trends.
