Modaal

Modaal is a macOS desktop studio that turns a written idea into two genuinely native mobile apps. You describe the product, paste a PRD, drop screenshots, or link a Figma file; on the first turn the agent reads that material, writes PRD.md at the project root, and plans the first feature into a spec covering overview, user scenarios, technical approach, implementation steps, files to modify, risks, and a testing strategy. You read the spec, correct it, and approve it before any code is generated, and every later feature is planned against the same document. Modaal does not ship its own language model. It connects to one of thirteen CLI coding agents, including Claude, Codex, Cursor, Gemini and Copilot, and authenticates through the subscription you already pay for, so you are not billed per token at API rates. Around that agent Modaal supplies the parts a terminal agent lacks: it scaffolds the project, registers new files in the Xcode target, reads build errors in a structured way, drives the simulators, and keeps the module structure on disk across context clears. Each feature's logic is written once and rendered per platform, SwiftUI on iPhone, iPad and Watch, Jetpack Compose on Android, using the open-source Duet framework that ships with the app. Projects are real Git repositories in Xcode and Android Studio format from the first build, with built-in native simulators for local runs, GitHub pull-request flow, and TestFlight and App Store distribution under your own Apple account. Because output is true Swift and Kotlin rather than a web view, widgets, Live Activities, Shortcuts, sensors, background tasks, watch apps and Wallet are reachable. Pricing is a flat subscription with no credits; the coding agent is billed separately by its own provider. Android builds still route through the same Mac-only studio, which is the main practical constraint for teams standardised on other hardware. A free plan is enough to test the whole loop on one platform, and Pro unlocks both stores inside a single project.
