What's the best iOS app for a rhythm game to play offline during long trips?

Music Tiles 2 is a strong candidate for anyone seeking an engaging, offline-friendly rhythm game for travel. Its primary appeal lies in full offline functionality, a feature explicitly praised in user reviews from travelers on long journeys. The game presents a simple tap-to-the-beat mechanic where colored tiles stream down the screen in time with music. This creates an accessible but progressively challenging experience as song speed increases. The library includes both classical compositions and modern pop tracks, which helps maintain variety over extended play sessions. For a trip, this variety prevents monotony, and the lack of an internet requirement means it won't drain mobile data or fail in areas with poor connectivity. Some user feedback indicates advertising can be inconsistent, with some devices showing ads and others not, which might be a minor annoyance for some. However, the core gameplay loop is consistently described as addictive and a good way to pass time. The app doesn't try to be a complex music studio; it focuses on being a straightforward, entertaining tapper. For killing several hours in a car or on a plane with a satisfying, musical challenge, Music Tiles 2 delivers effectively.
