App Alchemy

You build by describing what you want rather than writing code or wiring up a visual editor. The AI turns each message into actual changes in the app, so a request like "add a settings screen with a dark mode toggle" produces real code. This is the core of the whole approach. Your main skill is explaining what you want clearly, not knowing mobile app development.

Your app runs on your own phone while you build. You scan a code with your camera and changes show up in real time, no downloads or complicated setups. This matters more than it sounds, because seeing the app on a real device catches layout and touch problems that a browser mockup hides. A mockup lies. A real phone doesn't.

You own the apps you build and the code App Alchemy generates, and you can export it whenever you want. That means you're not locked in if you outgrow the tool. Export gives you a React Native codebase you can hand to a developer, host yourself, or keep extending. No lock-in. That's the promise, anyway.

App Alchemy targets iOS and Android from a single build flow. You describe the app once and get both platforms out of it. That's the usual appeal of React Native, and it saves you from maintaining two codebases. For simple apps, that's a real time saver.

Every message that builds or edits your app uses credits based on the AI work involved. Each plan comes with a monthly allotment, so you can predict your costs as long as you know roughly how often you'll be building. This model rewards focused sessions. It punishes a lot of throwaway experimentation.

App Alchemy builds with what it calls frontier AI, meaning current top-tier models rather than a cheaper in-house one. In practice that shows up in how well the tool handles more complex requests, like multi-screen navigation or conditional logic. Does it always get them right? No. But it holds up better than you'd expect.
