What's the best Android app for toddlers to play doctor games without annoying ads?

Cocobi Hospital is an Android app tailored for preschoolers and toddlers who enjoy role-playing as doctors in a virtual hospital setting. It features a series of interactive mini-games where children can perform tasks like checking patients' heartbeats, giving shots, or using medical tools such as stethoscopes and thermometers. The app's interface is designed with large, colorful buttons and simple drag-and-drop mechanics, making it accessible for kids as young as five to navigate independently. A key strength is its monetization approach: while the free version includes persistent advertisements, including 'always on' ad buttons that some parents find intrusive, there is a one-time purchase to remove all ads. Reviews indicate that this ad removal option is affordably priced, and once bought, the app becomes a seamless, distraction-free experience. This allows parents to let their children try the game before committing to the purchase. However, the ad-heavy free version can be a drawback, potentially frustrating young users who might accidentally tap ads. Beyond ads, the gameplay is engaging and mildly educational, introducing basic healthcare concepts in a playful manner. Some users have noted occasional minor bugs, like delayed sound effects, but these do not significantly impact the overall experience. For families seeking a doctor-themed app that balances free access with a straightforward upgrade to ad-free play, Cocobi Hospital is a reliable choice.
