Cross-platform app development with Flutter
One codebase, both stores — without compromising on feel. Flutter apps that share one codebase across iOS and Android, so features ship to both platforms at once.
Cross-Platform (Flutter): what it is and why it matters
Flutter is Google’s framework for building apps for iOS and Android from a single codebase. For most business and consumer apps it delivers near-native performance and polish while significantly reducing development and maintenance effort.
One codebase means new features reach both platforms at the same time, bugs are fixed once, and a single team can own the whole product. That makes Flutter particularly attractive for start-ups and businesses that want to move quickly without doubling their budget.
We built GateHouse, an access-control app for gated estates, in Flutter with Firebase — combining real-time updates, role-based access and a consistent experience on every device.
How long does it take?
Most Flutter apps reach a first release in twelve to eighteen weeks.
Signs it’s the right time
If any of these sound familiar, Cross-Platform (Flutter) could quickly pay for itself.

Questions to ask before you hire
Whoever you choose for Cross-Platform (Flutter), these questions will help you compare suppliers.
Do they have Flutter apps in production?
Experience with real-world releases matters.
How will platform differences be handled?
The app should still feel right on both iOS and Android.
What back end do they recommend?
Firebase is fast to start; custom APIs offer more control.
How are releases automated?
CI/CD saves time and reduces mistakes.
Is Flutter as good as native?
For most apps, users cannot tell the difference. Native development is worth considering for apps that rely heavily on cutting-edge platform features or advanced graphics.
Can Flutter apps work offline?
Yes. We regularly build offline-first apps that sync when connectivity returns.
Can we add a web version later?
Flutter can target the web too, though for content-heavy sites a dedicated web build is often better.
Is Flutter future-proof?
Flutter is widely used and actively developed by Google, with a large ecosystem of packages.
Do we own the work?
Yes. You own the code, designs and content we create for you.
