Lion's Eye is the best scanner available for Secret Lair editions, special variants, and cards with non-standard layouts. The premium tier adds collector number detection and auto-scanning, which further improve accuracy on difficult cards. For standard cards it performs well, but its real edge is on the cards that trip up every other scanner.

The interface is clean and functional, with a layout that makes scanning and browsing your collection straightforward. It follows iOS design conventions well, and recent updates have refined the overall experience. Navigation is intuitive even for new users.

Price data is available and generally accurate for the major marketplaces. For Secret Lair and variant cards specifically, having accurate price lookups is critical since these cards often have wildly different values from standard printings. The price tracking is reliable enough for informed trading decisions.

Collection management covers the essentials well, with good search and organization options. It handles the complexity of variant cards and special editions better than most competitors. The feature set is still growing, and the developer's responsiveness means requested features often arrive quickly.

Basic scanning is free, with the Plus subscription unlocking auto-scanning and collector number detection. The pricing is fair for the specialized functionality it provides. For collectors with significant Secret Lair or variant collections, the premium features pay for themselves through more accurate identification.
