Modaal

The ability to bring your own AI agent is another core feature. Modaal works with 11 supported agents including Anthropic’s Claude, Cursor, GitHub Copilot, Google Gemini, Mistral, Cline, and Open Code. Integration requires only one configuration line, thanks to the Agent Communication Protocol (ACP), which instantly gives any compatible agent architectural intelligence. This means the AI doesn’t just write code snippets; it understands how to structure an entire iOS app, reason about navigation flows, and separate concerns between UI, business logic, and data layers. Because you bring your own API keys, you never burn unpredictable credits inside Modaal itself. You pay for your own AI usage exactly as you want, maintaining full cost control while receiving senior-level architectural guidance automatically generated by the system.

Modaal doesn’t stop at basic screens—it helps your AI agent implement the full range of native iOS platform features. From widgets and Live Activities to Shortcuts, sensors, background tasks, Watch apps, and Wallet passes, the architectural blueprints cover the entire Apple ecosystem. When you ask your agent to build a widget, Modaal’s guidelines ensure it uses the correct WidgetKit APIs and updates properly. The same applies to background processing with BGTaskScheduler or real-time updates via Live Activities. This depth means your app can compete with professionally built software that takes full advantage of iOS capabilities. Instead of learning each framework individually, you rely on Modaal’s embedded expertise to steer the code generation toward correct, App Store–compliant implementations.

The overall workflow is built around vertical slices—a development method that delivers complete, working pieces of functionality rather than isolated layers. You start by describing your product idea in natural language. Modaal then prompts the AI to generate a Product Requirements Document (PRD), a user flow map, and a SwiftUI architecture plan. These artifacts are saved directly in your project repository, giving you and any future collaborators immediate context. With the plan in place, the agent is guided to implement one complete feature at a time, such as user authentication with Sign in with Apple, a home feed, or a settings screen, all the way from the interface down to the data model. This slice-by-slice approach ensures that you always have a functional, testable app after each iteration, rather than a fragile house of cards.

Real-world use cases highlight the power of this approach. A solopreneur at a company like Miro or Revolut can use Modaal to build a companion iOS app for their side project. They connect their existing Claude subscription, describe the app, and within days have a working prototype with widgets and background sync. When it’s time to polish in-app purchases or App Store submission, they can add a vetted iOS engineer through Modaal’s human-help system. The engineer works inside the same Xcode project at a fixed rate for a time-boxed session, solving StoreKit issues or crash bugs without rebuilding anything. Another scenario is an indie maker who creates a native watch app to accompany their fitness service, all while keeping costs predictable and never writing a line of Swift themselves.

Modaal is priced at a flat $9 per seat per month, offering a free 2-day trial with no credit card required. This contrasts sharply with credit-based competitors like Replit, Bolt, and Rork Max that charge you more as you build. The target users are solopreneurs, indie hackers, product managers, and non-coder founders who want to launch on the App Store without hiring a development team. They often work nights and weekends, value predictable costs, and need the flexibility to bring their preferred AI model. Because Modaal runs as a native macOS application, you get a fast, responsive experience with all code stored locally. In summary, Modaal is the AI native iOS app builder that combines bring-your-own-agent freedom with real Swift output, architectural certainty, and a simple flat rate—making it the definitive tool for shipping serious iOS apps without code.
