x1
From idea to iPhone app on the App Store, no coding
Visit website →About
x1 doesn't try to generate your entire app from one prompt. Instead, it guides you step by step: asking focused questions, designing each screen for review, then building the app in stages. You test it on your iPhone as you go.
It remembers the decisions behind your app — if you change something later, it updates the screens, flows, and features that depend on it instead of treating every request as a brand-new prompt. When ready to ship, it prepares your App Store listing, screenshots, and submission.
Starts free with 100 credits. Paid plans from $20/month. Built with React Native with source code export.

Why we picked it
x1 earns its spot for refusing the one-prompt-whole-app approach — guiding you screen by screen and remembering the decisions behind each one, so a later change updates everything that depends on it, is worth naming against tools that generate everything at once and leave you untangling the result.
