Modaal.dev
AI builder for native iOS and Android apps from a specDescribe an idea, get SwiftUI and Compose code.
Highlights
What you can do with it
- An independent developer ships a to-do app to both stores
- A startup imports a PRD and generates a dual-platform MVP
- A developer adds an Android version to an existing iPhone app
How to use it
- 1 Install the Mac client and register a free account
- 2 Connect your existing AI services in Settings
- 3 Create a project and describe the idea, or upload a PRD, Figma link, or screenshots
- 4 Review and approve the PRD and the first feature specification
- 5 Approve the spec to generate code, preview in the simulator, then publish
Who it is for
Pros
- A free plan with no credit card required to start
- It uses AI subscriptions you already pay for rather than billing for tokens
- Projects are standard and openable in Xcode or Android Studio
Limitations
- It is a Mac desktop client, so Windows and Linux users are left out
- Spec approval is a gate, so you must read documents before code appears
- Generated code still needs review, and free plan limits are not detailed
What Modaal.dev is
Modaal is a Mac desktop client that turns a product idea into native iOS and Android apps. You describe what you want in plain language, or upload a PRD, a Figma link, or screenshots, and it works in a spec-driven way: each feature starts with a PRD and a detailed specification covering user scenarios, technical approach, files to change, risks, and testing. Code is written only after you confirm the spec. The same business core produces SwiftUI for iPhone and Jetpack Compose for Android, with the UI layer kept native on each side and consistency checked between them. It connects to AI services you already subscribe to, such as Claude, ChatGPT, Codex, Gemini, and Copilot, instead of billing you for tokens. A free plan is available and no credit card is required.
What you can do with it
- Import an idea, a PRD, a Figma link, or screenshots as a starting point
- Review and approve specifications before any code is generated
- Build and preview both platforms in the built-in simulator on your Mac
- Open the generated projects in Xcode or Android Studio, or publish through TestFlight and Google Play
Who it is for
- Independent developers who want a native app without writing every screen
- Product managers who need a runnable prototype from an existing PRD
- Startup teams that need both platforms without a large native team
What to watch out for
This is a Mac tool. If you work on Windows or Linux there is no client for you, and the simulator depends on running locally rather than in a browser. The spec-driven flow is the point of the product, but it is also friction: you are expected to read and approve documents, and skipping that step removes the safeguards the tool is built around. It relies on your own AI subscriptions, so cost and rate limits come from those accounts rather than from Modaal. The generated projects are yours, but they are still code that needs review before you ship it to a store. What the free plan covers beyond initial signup is not detailed in the listing, and plan terms can change.
