a0.dev - AI Mobile Development Tool for MVP Building

AI Mobile Development • Freemium

a0.dev helps solo builders generate real React Native mobile apps from their phone using AI.

a0.dev

Best for:

• Rapid mobile MVP prototypes you can generate from your phone
• Solo founders or designers who need a real React Native scaffold quickly
• Creating UI/navigation scaffolds to hand off to developers

Not for:

• Apps requiring complex native modules or low-level device access
• Production-ready apps where performance, security, and polish are critical
• Teams who need tight version control and complex CI/CD out of the box

a0.dev advertises itself as a mobile-first way to “generate mobile app from your mobile,” and it mostly delivers on that promise. The tool runs on your phone, uses Claude 3.7 Sonnet behind the scenes, and outputs React Native apps (not mere web wrappers). That distinction matters: you get a real cross-platform codebase you can open in a dev environment. I think this is best if you want to sketch an app idea fast while away from your laptop or want a quick scaffold to hand to a developer. You can iterate UIs and basic navigation flows rapidly, and it saves the initial boilerplate and component wiring that normally eats hours. For single founders or designers who need clickable prototypes backed by real code, a0.dev is genuinely useful. Be clear about the trade-offs. The generated code often needs cleanup — variable names, styles, and platform-specific behavior can be messy. You’ll hit limits if you need native modules (Bluetooth, advanced sensors, custom animations) or production-grade performance tuning; expect to export the project to a proper IDE and rework parts of it. Debugging complex logic on a phone-first flow is also awkward. When to use it: rapid MVP sketches, demo-ready prototypes, and scaffolding simple CRUD or content-driven apps. When to skip it: if you need heavy native integrations, enterprise-grade security, or a polished, production-ready app without further engineering. Overall, a0.dev is an impressive phone-first generator for React Native prototypes — handy and quick, but not a replacement for hands-on mobile engineering when you need robustness and custom native features.

Tradeoffs:

Generates real React Native code quickly, but expect to clean up and rework parts for production; complex native features will need manual engineering.
