What's the best iOS app for experimenting with simple game design without needing to code?

Rezona is an iOS app that serves as a lightweight digital workshop for aspiring game creators or hobbyists. It demystifies game development by offering a library of pre-built game templates and visual components that users can drag, drop, and modify. The core appeal lies in its 'remix' functionality, allowing users to take existing game concepts shared by the community, tweak the rules, and insert their own assets like images and meme templates to create personalized variants. This approach is particularly effective for prototyping simple arcade-style games, interactive stories, or playful digital toys. Real-world scenarios include a teacher crafting an educational quiz game for students, a social media user making a custom game for a group chat, or a parent collaborating with a child to build a simple interactive birthday card. Reviews indicate the process can be genuinely engaging, with one user noting the addictive nature of 'messing with other people’s ideas.' However, the tool has boundaries; it's not suited for complex, high-fidelity game production, and some interface elements can feel a bit finicky. The app's strength is its low barrier to entry, but users should temper expectations regarding polish and depth compared to professional desktop engines.
