Overview

One Flutter codebase, two app stores, no compromises

Perfect for

  • Startups launching a mobile-first product
  • SaaS companies adding a companion app
  • Businesses replacing an outdated app

Building separate iOS and Android apps doubles the cost and the time to market, and the two versions slowly drift apart. Flutter solves that with one codebase that compiles to fast, native apps on both platforms.

We build Flutter apps with the polish users expect: smooth animations, responsive layouts and platform conventions where they matter. Alongside the app we build the backend it needs, usually with Laravel or Node.js, including authentication, APIs, an admin panel and push notifications.

Launch is part of the job. We prepare store listings, handle App Store and Google Play submission, and set up analytics and crash reporting so we can keep improving the app based on how people really use it.

Problems we solve

Sound familiar?

  1. 01

    Two native apps would blow your budget and timeline.

    One Flutter codebase for iOS and Android, with native performance and a single team.

  2. 02

    Your current app crashes, lags or gets poor reviews.

    We audit, stabilise or rebuild it, then monitor crashes and performance after release.

  3. 03

    You have an app design but no backend.

    APIs, database, authentication and admin panel built alongside the app.

  4. 04

    App Store rejections keep delaying launch.

    We build to store guidelines from the start and handle submission and review for you.
