What's the best Android app for tracking lost pets and ensuring their safe return?

Crumb is an Android app designed to help pet owners track and recover lost pets efficiently. The system centers on a durable QR code tag that attaches to a pet's collar. When someone finds a stray animal, they can scan the tag with any smartphone camera—no app required—to instantly view the pet's profile, owner contact details, and medical information. This feature is especially valuable in real-world situations, such as when a dog escapes during a storm or a cat wanders off in an unfamiliar neighborhood. Owners receive GPS location alerts the moment the tag is scanned, enabling quick retrieval. The app also automates notifications to pre-registered veterinarians if a pet goes missing, adding a layer of professional oversight. Users report that the interface is intuitive and setup takes just minutes, with many highlighting responsive customer service that resolves issues promptly. On the downside, Crumb requires a subscription, which may deter budget-conscious users. Still, the inclusion of free tag replacements and the overall reliability make it a strong option for pet safety.
