Flutter agency: one codebase for iOS and Android apps

Flutter is a framework created by Google for building iOS and Android apps from a single codebase, written in the Dart language. It draws its own interface, which guarantees a consistent, smooth look on every phone. For a business, it is often the best balance of cost, time and quality: one development, one maintenance, two published apps.

Good fit

When to choose Flutter?

  • iOS and Android at the same time

    One project instead of two: lower budget and shorter timelines.

  • A custom design

    An interface true to your brand, identical on every device.

  • A service app

    Booking, ordering, loyalty, client area, tracking.

  • A fast prototype

    Testing an idea with real users before investing more.

In all honesty

When it isn't the best choice

If the app relies heavily on very platform-specific features (advanced augmented reality, smartwatches, complex widgets), native development in Swift or Kotlin may be preferable. And if a web version is enough, a progressive web app costs less.

Typical projects

What we build with Flutter

Booking app

Time slots, payment, reminders, history.

Loyalty app

Card, points, offers, notifications.

Field app

Offline data entry, photos, sync when the network returns.

Companion app

A mobile extension of your website or platform.

Existing code

Takeover, migration and maintenance

A Flutter app that is not updated eventually gets rejected by the stores, which regularly require new system versions. We update Flutter and its libraries, fix incompatibilities and republish. We also rewrite in Flutter apps developed separately for iOS and Android, so there is only one codebase to maintain.
