The right tool, not one tool

Flutter is our usual choice, but not our only one. We recommend the approach that suits your product, and every option here is one we've shipped.

  • Flutter

    Most apps that need to be on iOS and Android, and often the web.

    ExampleEmbers of Strength and the women's fitness membership

  • Capacitor

    A web product that also needs to be in the app stores, sharing one web codebase.

    ExamplePaws In: app, website and admin CMS

  • Native iOS and Android

    Apps that depend on specific device hardware or the very latest platform features, built in Swift for iOS and Kotlin for Android.

    ExampleDuo Party, built around the iPhone Duo's fold

How app rescue works

Flutter questions

Is Flutter as good as a native app?

For most products, yes. Flutter apps compile to native code and feel smooth and polished on both platforms. Where an app depends on specific device hardware or brand-new platform features, we'll recommend native iOS or Android development instead and explain why.

Will one Flutter app work on both app stores?

Yes. One codebase produces the iOS and Android apps, and we handle the App Store and Google Play releases.

Can the same app run on the web?

Yes. Flutter web lets the product run in the browser and share code with the mobile apps. For content-heavy public websites we may suggest a separate site, so it loads fast and ranks well.

Can you take over our existing Flutter app?

Yes. We can assess it, fix what is blocking you, upgrade it to current Flutter and packages, and keep it improving. If it's stuck, see our app rescue page.

Which back end do you use?

Whatever suits the product: Firebase, Supabase or a custom API. We'll explain the trade-offs in plain English, including running costs.

How much does a Flutter app cost?

Every project is scoped to fit. One codebase for every platform usually makes Flutter the cost-effective choice, and you'll know what it costs before any work begins.
