Cross-platform APP development

One app for iOS and Android instead of two. Faster to build, cheaper to maintain, and easier to keep consistent across platforms, built by a team that gets the framework right for your product.

Our collaboration models

What we do

Flutter development

We build Flutter apps that share one codebase across iOS and Android, without cutting corners on native performance. Our engineers handle platform channels, custom animations, and state management to match what each platform’s users expect.

Our specialist knowledge includes:

  • Detailed understanding of the declarative nature of Flutter
  • Component-oriented architecture and software testing
  • Experience in publishing Dart/Flutter libraries to the pub.dev repo

React Native development

We build React Native apps for products that need to move fast without losing quality, from consumer apps to complex financial platforms. Our engineers write native modules when performance demands it, so you’re never boxed in by the framework’s limits.

Our specialist knowledge includes:

  • Writing bridges to connect native modules with JavaScript
  • Redux for state management and Redux-Sagas for async side effects
  • Declarative UI paradigm to manipulate native views directly

Kotlin Multiplatform

For teams that want to share business logic without giving up native UI, we build with Kotlin Multiplatform (KMP). Core logic, like networking, data models, and business rules, stays in one shared codebase. iOS and Android interfaces stay fully native, built with SwiftUI and Jetpack Compose.

Our specialist knowledge includes:

  • In-depth understanding of Kotlin’s shared code architecture
  • Expertise in building platform-specific modules alongside shared logic
  • Proficiency in publishing libraries to repositories like Maven Central and custom artifact systems
  • Advanced experience in integrating Kotlin Multiplatform with native APIs and third-party libraries
  • Porting existing Android apps to iOS by reusing the existing Kotlin codebase, enabling cost-efficient cross-platform development while preserving performance and functionality

Why it works so well

Senior engineers only

42% of our engineers hold an M.S. in Computer Science, and we hire only the top 1.5% of applicants who apply. You get people who’ve already solved this problem before.

Agentic engineering

Our engineers use AI to handle repetitive work, then review every line themselves. That combination cuts timelines in half without cutting corners on quality or introducing risk you can’t see.

The best open source frameworks and libraries

Our senior engineers pick the right tools for the job, not the trendiest ones. We take advantage of the best the market offers, so we spend less time on standard elements and more on the features that matter.

One team, one project

Once your team is assigned, they work only on your product, nothing else. No context switching between clients, no rotating engineers. The people who start your project are the people who finish it.

Seeing it through to launch

Your dedicated team stays with your product through app store submission and approval on both platforms, guiding you on best practices for a smooth release, not handing off once the build is done.

Benefits of cross-platform development

  • One codebase for iOS and Android, less duplicate engineering work
  • Faster time to market, ship both platforms at once
  • Lower cost, one team instead of two
  • Easier maintenance, fix once, deploy everywhere
  • Consistent UX across platforms

Still not sure whether to go for native or cross-platform?

Cross-platform apps we’ve built

We’ve loved working with many fantastic companies, and are really proud of the cross-platform apps we’ve created with them.

Still unsure about something?

Don’t worry, whatever it is, we’ve got you covered in our FAQ.

We review your product requirements, timeline, and existing team before making any recommendations. Flutter and React Native cover most use cases well. We recommend Kotlin Multiplatform when you need deep hardware access or heavy platform-specific performance work.

For most products, yes. Flutter and React Native handle demanding, animation-heavy interfaces well today. When a specific feature requires native-level performance, such as camera processing or Bluetooth, we write that component natively and keep the rest of the app shared.

It depends on scope, but we’ve taken cross-platform MVPs from kickoff to launch in a few months. A Flutter fitness app we built for a Canadian startup launched on both app stores and hit 11,000 downloads in its first month.

Yes. We’ve helped teams move from separate iOS and Android codebases into a single Flutter or React Native app, migrating feature by feature so you’re never stuck maintaining two versions mid-transition.

We set up CI/CD pipelines that build, test, and release to both app stores from one codebase. Over-the-air updates handle most fixes without a full store review, so critical patches reach users fast.

NEXT STEPS

Before we start our partnership, we have to make sure
we’re a right fit for you.

Over a relaxed call or two, we’d like to hear as much as possible about your project
(fully NDA’d of course).

We’ll talk about:

  • Your expectations
  • Services you need
  • Your vision

There are a few steps in this phase:

  • We’ll hand-pick a team based on your desired seniority level and other requirements.
  • We’ll send you their CVs so you’ll know every engineer working for you.
  • If necessary, we can set up interviews between you and every engineer.

Only when you’re 100% on board with our choice, we’ll go to the next phase.

If everything sounds good to you, we’re ready to get started.
