What's the best iOS app for prototyping app concepts with AI assistance?

Rork is an iOS application focused on accelerating app development through integrated AI tools. It caters to entrepreneurs, hobbyists, and developers who need to quickly transform vague concepts into tangible prototypes. The app's core functionality includes an AI-driven idea generator that produces app concepts based on user input, alongside built-in project management for organizing these ideas. For instance, a user can describe a basic app goal, and Rork's AI suggests features, layouts, or even code snippets to kickstart development. This makes it particularly useful for brainstorming sessions or early-stage validation without extensive coding knowledge. Reviews indicate that many appreciate the speed, with one user noting it helped create 'years worth of ideas in under an hour.' Specific features like real-time AI feedback and a streamlined interface for editing projects contribute to its efficiency. However, the app isn't without flaws. Some users report stability issues, such as crashes when reopening projects or bugs that hinder upgrading to premium tiers, which unlock advanced editing tools. Despite these hiccups, Rork's AI capabilities and intuitive design make it a solid choice for rapid prototyping, though potential buyers should be aware of the occasional technical glitches that the developer may need to address in updates.
