Review:
"Ruff's Bone is an animated interactive storybook that follows Ruff the dog's zany hunt for his bone from the yard next door to another planet and back home again. Almost every object is animated and our kid testers had predictable fun searching for the hidden animated surprise on each page. Tension builds as users try to beat Ruff in finding his bone. This app is based on the gifted Eli Noyes' book of the same title.

The developer is to be commended for advancing reading skill development in a well-crafted, extremely intelligent manner."

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
