The old answer to how to build an iOS app without code was a no-code wrapper around a web app. That worked for simple content tools, but it fell apart when you needed real navigation, push notifications, subscription flows, offline behavior, or a developer handoff. The newer answer is to create iOS app with AI: describe the product in plain language and generate a React Native app you can preview, refine, and export.
AppGenie uses Expo + React Native because it gives founders one practical path for iOS, Android, and web without trapping the product inside a closed visual builder. You can start without coding, then bring in a developer later with real files instead of a platform-specific project that cannot leave the tool.
Define the native iOS behavior first
Before you generate, write the app like a user story. Who opens it, what do they do in the first session, and what native behavior matters? A fitness app might need daily reminders, progress charts, and Apple-style onboarding. A marketplace might need saved searches, chat, payments, and push notifications. A camera app needs permission handling and media upload. Say those things in the prompt.
The point is to give the AI enough product shape to create screens that feel connected rather than decorative. “Build an iOS habit app” is a weak brief. “Build an iOS habit coaching app with onboarding, a seven-day plan, daily check-ins, streaks, push notifications, and a paid Pro upgrade” is a buildable brief.
Generate, then test the first path
The first generation should give you the app shell: navigation, screens, components, state, and the first version of the core flow. Do not judge it only by screenshots. Click through onboarding, complete the main task, open settings, and look for dead ends. An iOS app is not a landing page. It has to feel coherent across multiple screens.
When something is missing, prompt for that specific change. Ask for “add a notification permissions screen after onboarding” or “add a subscription comparison screen before checkout.” Focused refinements are easier to verify and less likely to disturb the rest of the app.
Prepare for the App Store handoff
No-code does not remove Apple's release process. You still need an Apple Developer account, app metadata, screenshots, privacy details, and testing. What AI changes is the starting point: instead of paying for a custom build before you know the product works, you can generate the app, iterate on the flow, and export a codebase for review when the product is worth submitting.
That export matters. If your app becomes serious, a developer can open the project, inspect the generated components, wire production services, and prepare the build pipeline. That is a much cleaner handoff than rebuilding a no-code project from scratch.
Where AppGenie fits
AppGenie is designed for founders who want the speed of no-code but the ownership of source code. You can describe a consumer app, marketplace, SaaS mobile companion, community app, or internal workflow and get an Expo project with real screens and navigation. Then you can refine the project with follow-up prompts as the product gets sharper.
