Create an iPhone app without starting from code.

Rey’s iOS app builder brings visual design, AI, data and publishing together. Build the screens your audience needs, connect user accounts and content, and test the complete experience on your iPhone before launch.

Begin with a free app template or create your own layout. The Luna meditation template shown above is one starting point: replace its sample content, change the design, and shape the navigation around your app.

You can work on the interface using Rey’s drag-and-drop app builder, then preview in the Rey mobile app and use TestFlight for pre-release testing. Rey guides you through connecting your Apple developer account and submitting a build.

Apple reviews App Store submissions independently. Read Apple’s submission guidance and App Review Guidelines when preparing your release.

An app you can test before you launch.

An attractive screen is a starting point. Preview your iPhone app as you build, then test the complete journey: creating an account, finding content, completing an action and returning to the app later.

Use TestFlight to collect pre-release feedback. Testing gives you a chance to find confusing navigation, missing content and broken flows before your App Store audience encounters them.

Prepare for Apple’s review.

Your App Store release needs more than an app build. Plan your app name, icon, description, screenshots and privacy information. If reviewers need access to signed-in content, prepare the information they need to evaluate the experience.

Rey handles the build and submission workflow without requiring you to set up your own Xcode deployment pipeline. You remain responsible for the content, account configuration and information you submit to Apple. Approval and review timing are determined by Apple.

Plan your publishing and subscription costs.

You can start designing your iPhone app on Rey’s Free plan. Publishing to iOS requires Rey Pro and your own Apple Developer Program membership. Keep those costs separate when planning your launch budget.

If your app offers premium content, Rey Pro includes paywalls with RevenueCat. Review Rey’s pricing and Apple’s developer membership information for current details and fees.

What our users say

As a solo founder building EDGE, an emotionally intelligent AI app, I needed more than drag-and-drop features. With Rey, I’ve been able to shape a deeply personalized and privacy-first user experience without a dev team.

I’m genuinely excited about what a tool like Rey could mean for the future of femtech, and for every so-called “niche” space that’s been underserved for too long.
