New App “Sniffr” Lets Dogs Rate Every Smell in Their Neighborhood

A new smartphone app called Sniffr is gaining popularity among dogs, allowing them to rate and review scents encountered during walks. The app features categories like “Best Fire Hydrant,” “Top Trash Can,” and “Most Mysterious Bush.”

Developers aim to integrate cat feedback next year, though early testers say cats rated every smell a 1-star annoyance.
