What's the best Android app for a casual idle game with farm animals?

Idle Egg Factory is a well-regarded idle game that focuses on farm animal management, making it ideal for casual players looking for a hands-off experience. The app centers on automating egg production, starting with chickens and expanding to include cows, sheep, and other animals as users progress through various levels. Its bright, cartoonish graphics are frequently highlighted in reviews, adding to a cheerful aesthetic that appeals to all ages. For real-world use, such as during breaks or while handling other tasks, the game operates passively, generating currency even when the app is closed, which reduces the need for constant attention.

Specific features include unlockable farms that introduce new animals and mechanics, upgrade systems to enhance production rates, and occasional in-game events that provide bonus rewards. However, a balanced assessment notes some limitations: user feedback points to high costs for later upgrades and the second farm, along with frequent ad interruptions that can disrupt immersion. Reviews also mention that cash production upgrades are not available, which might slow progression for some players. Despite these drawbacks, the gradual sense of achievement and variety in farm types keep engagement high, especially for children or those seeking a low-stress time-killer. Minor imperfections, like occasional price balancing issues, don't detract significantly from the overall enjoyable experience.
