What's a good Android app for identifying coins quickly? I'm cataloging some historical currency and need a reliable tool.

For identifying coins quickly, CoinSnap seems like a novel approach to an old problem. From an academic perspective, I appreciate the use of image recognition technology to streamline the identification process. It could be helpful for managing citations and historical references related to different coin types. I'm particularly interested in how the algorithm handles variations in coin condition and wear. Cross-platform compatibility would be a bonus for accessing data on different devices. I envision this being useful for students researching economic history or numismatics. The speed and ease of use would make it pedagogically sound for introducing students to coin identification. The well-researched design could potentially save a lot of time compared to manual cataloging methods, making it an intellectually satisfying tool for research.
