Build native iOS and Android apps at once, with your own AI

From idea to the App Store and Google Play.

Describe your idea, refine the plan, then build feature by feature and flow by flow until both apps are ready to release.

iOS + Android, simultaneously

Spec-driven development

Top architecture from prompt one

Bring your own subscription

Built-in simulators

Real Xcode & Android Studio projects

Easily publish your apps

GitHub integration

Build native iOS and Android apps simultaneously, from one core.

Each feature's logic is written once. The iPhone app renders it in SwiftUI; the Android app renders it in Jetpack Compose.

One shared core

Two 100% native UIs

Parity checked by the build

iPhone now, Android later

Only true native iOS and Android apps can do all of this.

Real Swift and Kotlin talk to the phone directly — no web view, no bridge in between. Widgets, the watch, live activities, sensors, wallet: yours from day one, at full performance.

Widgets

Live Activities

Shortcuts

Sensors

Background Tasks

Watch Apps

Wallet

Every feature starts with a plan you approve.

On the first turn the agent reads your description — or your PRD, screenshots, a Figma link — writes PRD.md at the project root, and plans the first feature into a spec: Overview, User Scenarios, Technical Approach, Implementation Steps, Files to Modify, Risks & Open Questions, Testing Strategy. You read it, correct it, approve it. Only then is the code written. The specs stay in the project, so feature fifty is planned against the same document as feature one.

"I spend 80% of my time reviewing plans — so the code has no surprises for me. Modaal gives you the same."

Build the real thing, not another demo.

We've spent the last 15 years building native apps — for clients, for Fortune 500 companies, and as our own products. Shipping 100+ of them taught us one thing: structure is what separates the apps that last. Modaal is that structure, packaged — so you can ship like a team that's done this a hundred times.

Start free. Ship 2x native.

Download Modaal for Mac, connect the agent you already use, describe the first feature. Free plan, no credit card.
