Modaal: plan-led native iOS and Android development from a Mac workspace

Modaal is advertised as a Mac application for building native iOS and Android apps with an AI agent. Its workflow centers on approving a plan before generating code, then developing features and flows until the projects are ready for release.

A specification before each feature

The site describes an initial turn in which the agent reads an idea, product-requirements document, screenshots, or Figma link. It writes PRD.md at the project root and prepares a feature specification covering user scenarios, technical approach, implementation steps, affected files, risks, and testing.

The user reviews and approves that specification before coding begins. Keeping the documents in the project is intended to give later features the same reference as the first, rather than repeatedly recreating the design intent.

Modaal also offers Production, Duet, and Quick prototype architecture choices. The public page presents these as structures the agent follows; it does not supply evidence that every generated application is production-ready merely because that option was selected.

Shared behavior, platform-specific views

The described dual-platform approach uses a shared behavioral core with separate views: SwiftUI on iPhone and Jetpack Compose on Android. The page says both apps replay the same fixtures and a mismatch fails the build.

That is a stated parity check for the covered behavior, not a guarantee that all device features or edge cases behave identically. Users can start with one platform or both and add Android later. The Duet framework is described as open source.

The projects remain real Xcode and Android Studio projects in Git on the user's disk. Local native simulators support running them, while GitHub integration supports pushes, pull-request review, and team workflows.

Agent access and release responsibilities

Modaal says users can bring an existing Claude, ChatGPT/Codex, Gemini, Copilot, or other subscription instead of paying token-based API prices through that workflow. This is the vendor's integration claim, not proof of an official partnership or a guarantee that every account's plan grants every advertised use.

The page advertises a free plan without a credit card but does not state complete limits or paid pricing in the captured material. TestFlight and App Store distribution use the user's own Apple account.

The appeal is a visible approval process alongside local, editable native projects. Generated code, platform permissions, fixtures, and release settings still need review. The public description explains the intended workflow; Franklin has not built or submitted an app with it to establish its success rate.
