What's the best iOS app for offline entertainment for young kids during travel?

Toca Boca World is a digital playset that offers a sandbox environment for children to explore and create their own stories. It's particularly effective for travel entertainment because it functions entirely offline, making it ideal for car rides or flights where internet access is limited. The app includes features like customizable characters, buildable houses, and various locations for role-playing, which encourage imaginative play without structured goals. User reviews highlight its success in keeping kids occupied for hours, with one noting, 'it always keeps you entertained no Wi-Fi included and in a road trip you could play it.' However, some limitations exist, such as occasional technical glitches like unexpected logouts, as mentioned in feedback. Additionally, while the base game is free, many expansion packs require in-app purchases, leading to requests for more free content from users. Despite this, the app maintains high ratings for its kid-friendly design, lack of ads, and safety features. For parents seeking a reliable way to foster creativity and minimize screen-time friction during journeys, Toca Boca World delivers a robust solution, though monitoring in-app purchases is recommended.
