Product Engineering

Mobile App Development

iOS and Android apps built for everyday use.

What’s included

  • App UX and interface design
  • Cross-platform development with Flutter
  • APIs and back-end services
  • Push notifications and deep links
  • In-app payments and subscriptions
  • Analytics and crash reporting

Overview

Why it matters

People judge an app within the first few taps. We design and build mobile apps that are fast, clear and dependable — shopping apps, streaming and content apps, booking tools and companion apps for existing platforms.

We build with Flutter, which gives one codebase and consistent quality on iOS and Android. Back-end APIs, push notifications, analytics and store submission are part of the same project, so the app launches as a complete product rather than a front-end waiting for its server.

Who it’s for

  • Retailers adding an app to an existing online store
  • Platforms that need web and mobile on one back-end
  • Startups launching a mobile-first product
  • Businesses whose current app is slow, unstable or hard to update

FAQ

Questions clients ask first

Do you build separate apps for iOS and Android?

Usually not. We build with Flutter, which gives one codebase and consistent quality on both platforms, and add platform-specific code where a feature needs it.

Can the app share a back-end with our website?

Yes. We design APIs so the website, the apps and the admin tools all read from the same source of truth.

Will you publish the app to the stores?

Yes. We prepare the listings and screenshots and handle submission under your own developer accounts.
