    Why Modaal exists

    Build the real thing, not another demo.

    AI tools get you a demo in an afternoon — then the real app begins, and without structure it falls apart. Modaal is the structure: a senior architect in the workflow — architecture decided up front, features planned before they're built, wrong turns caught while they're cheap, codebase consistent as it grows.

    Share the logic, not the screen

    Cross-platform makes your apps look the same. Duet makes them think the same.

    Cross-platform tools like React Native and Flutter give you one screen design for both phones — and users can tell. Duet shares the other half: what your product does lives once, tested and shared. How it looks lives twice — an iPhone app that behaves like iPhone, an Android app that behaves like Android. Same behaviour, checked by the build on every release.

    The same feature running side by side — native iPhone simulator and Android emulator inside Modaal

    One shared core

    Business logic and feature state live once — pure, tested, the single source of truth for both platforms.

    Two 100% native UIs

    SwiftUI on iPhone, Jetpack Compose on Android. No web view, no bridge — every native SDK, all the hardware, full performance.

    Parity, guaranteed by the build

    The build replays the same scenarios on both platforms and fails on any mismatch. Divergence is a decision, never an accident.

    Duet is open source, and inside Modaal it saves your agent tokens on every feature. → Explore Duet

    Pricing philosophy

    Others sell credits. We sell certainty. You pay less.

    Every other tool meters your iteration — and iteration is where apps get good. Modaal is flat: bring any of 13 supported AI agents you already pay for. No per-token markups, no credit burn — and the workspace makes your agent's tokens go further.

    The workflow no other tool has

    You approve the plan. Then it gets built.

    For every feature, your agent writes a plan first — scenarios, approach, risks. You read it, correct it, approve it. Only then does the code get written. Those plans become the map of your project: in charge at feature fifty exactly as at feature one.

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

    Solo to team

    Build it once. Ship it everywhere. Never start over.

    Xcode & Git

    Code on your Mac, not locked in a cloud editor.

    Specs ship with code

    Decisions documented; new teammates get context instantly.

    Solo → team

    Shared feature maps and tasks. Nobody starts from zero.

    Native features

    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.

    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.
