What's the best iOS app for scanning and valuing sports cards?

CollX is specifically designed for sports card collectors who need to quickly identify and value their collections. The app's scanning technology allows users to point their phone camera at any sports card and automatically recognize it within seconds. Once identified, CollX pulls current market data from its extensive database to provide accurate pricing information. This functionality proves particularly useful when sorting through large collections or evaluating recent acquisitions. Beyond simple identification, the app maintains a digital inventory of scanned cards and tracks their value over time. Users frequently mention the scanning accuracy as a standout feature, though some note occasional difficulties with older or damaged cards. The marketplace integration allows collectors to immediately list cards for sale after scanning, creating a streamlined workflow from identification to transaction. While the free version handles most basic needs, serious collectors may find value in the premium features for bulk scanning and advanced analytics.
