Modaal for Android - Ship on both stores from one project using Swift + Kotlin

by
•
Modaal for Android let you ship one app to both stores with your own AI agent - no rebuild. Rather than one React Native codebase that draws the same screens on both phones, Modaal shares the logic, not the screens: your agent writes real Swift/SwiftUI for iPhone and real Kotlin and Jetpack Compose for Android from one project, and the build proves both behave the same. So anyone who built an iPhone app with Modaal can add Android without touching a line of logic — no credit meters, no rebuild.

Congrats on the launch! What happens when a feature work differently on each platform?

Maker

 Thanks for the question! Duet (the framework behind Modaal-build Android + iOS apps) supports two variants of "features": 1) a Kotlin-multiplatform implementation that defines types, protocols, and the the behavior (i.e. the reducer that produces state changes and effect), which is consumed by both iOS and Android app shells (thin SwiftUI and Compose surfaces that render the state); or 2) a "dual" implementation (Kotlin- and Swift-based reducers), that are validated against each other by behavioral tests that produce and then compare the fixtures - that two cores behave identically --
So, ideally, there is no situation when two cores work "differently".

well done!

Maker

 Thank you!

I built my IOS app and I’m going to start android with modal it’s greater opportunity 🔥

Maker

 Great! Looking forward to seeing you build! Also, join our Discord comunity - we run Hackatons, and events -

Thanks for giving us such helpful tool to build native apps! Congrats on the launch, !

Maker

nice product! this is exactly what i've been looking for for a while, but i'm on windows :( do u plan to release a windows version too?

Maker

 I'm interested in your use case, can I ask a few questions? Do you plan to work/release an Android app only, or both Android and iOS? How long are you planning to work on them (in weeks/months)? We might add support for building Android apps natively on Windows, is there is enough demand. Alternatively, you might want to check for running Modaal remotely - with full iOS and Android support.

 thanks for the suggestion!

i'm planning to release both an Androind and an iOS version

if the apps go well, i'd definitely be interested in working on them for months (like improving them, adding more features, etc...)

Woild love to see you in our Discord community: We’re running buildathons and workshops. The next one starts next week:
Very cool! What’s your support like for elixir/phoenix apps?
Maker

 Do you have any specific mobile app wrapper for elixir/phoenix in mind?

Because Modaal builds native apps (Swift/Kotlin) on the Duet ramework (again, native mobile app-level framework for native Swift/Kotlin apps). They are not directly comparable in any meaning.

real swift + real kotlin from one project is the right call, no react native tax 👏 congrats on android! how do you keep both builds in sync when the logic changes?

Maker

 Thanks! The logic core is either a single Kotlin Multiplatform module shared by Android and iOS apps; or two "pure" functional modules, with their behavior recorded and cross-tested on every change -
