App Builder

App Builder helps you plan, design, build and launch mobile and web apps by chat. Describe your idea and it turns it into a clear plan, screen copy and working code you can run. What you can do: - Plan your app: the problem, users, MVP features, screen map, user flows and data model, before any code. - Build a working app: a complete web app that installs on phones, an Expo React Native mobile app, or a clickable prototype to test with users. - Start from a template: starters for booking, fitness, habit tracking, marketplaces, delivery, CRM, social, learning and more. - Write the screens: onboarding, sign-up and sign-in, paywalls, settings, help and support copy, plus feature specs with acceptance criteria. - Check your store listing: paste your App Store or Google Play listing to get scores and fixes for length limits, keywords, metadata rules, readability and conversion. - Edit and export code: change existing code from plain-English instructions, or convert it to Expo, Flutter, SwiftUI, Jetpack Compose, React, Next.js or Vue. - Launch and grow: ASO, screenshots, release notes, ratings and reviews, retention, launch marketing, starter legal texts and a launch checklist. - Get a build link: turn your plan into a link that opens an online app builder with your app brief already filled in. Who it is for: founders, small business owners, creators, product managers and anyone who wants an app without hiring a development team first. How the tools work: the listing checker analyzes only the listing text you share in the conversation. It never opens store pages, and the text you send is not stored. The build link opens an online app builder with your brief and includes the plugin creator's affiliate code. App Builder is an independent plugin and is not sponsored or endorsed by that builder. Limitations: App Builder writes plans, copy and code in the conversation. It does not publish apps to the App Store or Google Play, create developer accounts or connect to your app's backend. Store rules change and each store reviews every app, so approval is never guaranteed. Legal texts are starter drafts, not legal advice. Details it cannot know about your app, such as prices, reviews and contact details, are marked for you to confirm or fill in. Replies that include the build link end with a short affiliate disclosure.
