What's the best Android app for keeping a toddler entertained with simple, music-based games?

Pinkfong Baby Shark is a collection of touch-based mini-games and musical activities centered around the globally popular children's song. For parents seeking a digital distraction for their toddler during short waits or quiet time, the app provides a familiar and colorful interface. Specific features include rhythm-tapping games where children can interact with the Baby Shark family, simple puzzle-matching activities, and various sing-along videos. The controls are intentionally basic, often requiring only a single tap, which makes it accessible for children as young as two. Reviews indicate that the app successfully holds the attention of its target demographic, with users frequently mentioning that their young relatives 'love it very much.' However, the experience is sometimes marred by technical issues. Several user reports across multiple reviews mention bugs that require fixing, suggesting occasional instability that can interrupt play. While the free version offers substantial content, it is supported by ads and in-app purchases for additional games, which is a standard model for this category. For brief, supervised play sessions that combine music and simple motor skill practice, Pinkfong Baby Shark serves its purpose, provided one tolerates its occasional rough edges.
