What our Cross-platform app development covers
Every major approach, chosen by evidence for your product rather than by habit for ours.
Flutter builds
Dart-based delivery with pixel-exact custom UI across iOS, Android, web, and desktop, best when brand-heavy design and platform parity matter most.
- ✓Custom widget libraries
- ✓BLoC or Riverpod state discipline
- ✓Web and desktop targets
- ✓Impeller rendering tuned
React native builds
TypeScript-first delivery on the New Architecture, strongest when your team knows React and web and mobile should share logic and libraries.
- ✓Expo or bare workflows
- ✓Hermes and Fabric enabled
- ✓Shared web-mobile logic
- ✓OTA update pipelines
Kotlin multiplatform and alternatives
For teams with existing native investment, KMP shares business logic while keeping fully native UIs, the right answer more often than its buzz suggests.
- ✓Shared logic, native UI
- ✓Swift and Kotlin interop
- ✓Incremental adoption paths
- ✓Honest fit assessment
PWA and Web-first clients
Where store distribution is optional, an installable PWA can replace the mobile apps entirely, cutting both codebases and the store commission.
- ✓Offline-first service workers
- ✓Web push and installability
- ✓Low-end device performance
- ✓Store wrapper options
Migration between approaches
Off a dying framework (goodbye, Xamarin), from two native codebases to one, or from cross-platform back to native where reality demanded it, we have done all three.
- ✓Framework exit plans
- ✓Native-to-cross-platform migrations
- ✓Incremental module strategies
- ✓Parity audits first
Store submission and release ops
Whatever the framework, the tail is the same: signing, flavours, store listings, phased rollouts, and crash monitoring wired before launch.
- ✓Dual-store pipelines
- ✓Environment flavours
- ✓Crash and analytics wiring
- ✓Phased rollout and rollback
What every engagement includes
Every cross-platform project ships with the following, agreed in writing before the first sprint begins.
Discovery workshop
A structured workshop maps your goals, users, and constraints into a scoped cross-platform roadmap with a fixed written quote before any sprint starts.
Named senior team
You get named, senior engineers with CVs you can review, not a rotating bench. The people in the kickoff are the people who ship.
Sprint demos every two weeks
Working builds are demoed live each cycle with CI running on every merge, so progress is visible in software, not slideware.
100% source-code ownership
All cross-platform source, configurations, designs, and documentation transfer to you on delivery with no licensing strings or vendor lock-in.
60 days of post-launch support
Engineering time is on standby for two months after go-live to triage defects, tune performance, and stabilise the release at no extra cost.
12 months of free updates
Compatibility updates, security patches, and framework upgrades ship free for a full year after handover.
insight
How to choose a Cross-platform approach
The honest decision factors are your team's existing skills, how custom your UI is, how deep your hardware needs go, and whether web shares the roadmap. Flutter wins on UI consistency and rendering control; React Native wins on JavaScript ecosystem reuse; KMP wins for teams protecting native investment; a PWA wins when the store is optional overhead.
We compare these approaches in depth on our Flutter app development and React Native app development pages, and our blog post on native vs cross-platform in 2026 covers the current data. Discovery ends with a recommendation we would defend in production, even when it is not the framework you expected.
The stack behind our Cross-platform builds
What we use across the approaches, stated plainly.
Flutter toolchain
Dart with sound null safety, Riverpod or BLoC, Drift and Hive for local data, golden and widget tests in CI, and Codemagic or Fastlane release pipelines.
React native toolchain
TypeScript strict, Expo and EAS where they fit, Reanimated for 60fps interaction, Detox or Maestro for E2E, and MMKV for fast local storage.
Kotlin multiplatform
KMP for shared domain logic, SQLDelight for shared persistence, Compose Multiplatform where shared UI earns its place, and native Swift or SwiftUI keeping platform polish.
Shared backend layer
Typed API contracts (OpenAPI or tRPC) generating SDKs for every client, so cross-platform parity is enforced by the compiler rather than by hope.
Quality gates
Device-lab testing across the low-end hardware your users hold, performance budgets per platform, and accessibility passes on every release candidate.
AI features
Shared AI service layers across clients, on-device inference via ML Kit, TFLite, or Core ML where latency or privacy demands it, with graceful offline degradation.
How a Cross-platform project runs
Six stages, starting with the framework decision rather than skipping it.
- 01
Discovery
Product goals, platform matrix, hardware needs, and team skills are mapped, and the framework decision is made with evidence before anything is quoted. Sometimes the answer is native; we say so.
✓ step 01 complete - 02
Design
Design tokens map directly to the chosen framework's theming system, so one design system produces consistent output across every platform target.
✓ step 02 complete - 03
Architecture setup
Project structure, CI, flavours, and shared contracts are scaffolded in week one, with a walking skeleton running on real devices across all targets.
✓ step 03 complete - 04
Sprint delivery
Two-week sprints with demos on real devices. Parity decisions are made explicitly each sprint and documented, ending platform drift before it starts.
✓ step 04 complete - 05
Hardening and launch
Device-lab passes, store compliance checks for both stores, phased rollouts configured, and crash monitoring verified before the first external user arrives.
✓ step 05 complete - 06
Support and handover
60 days of included support, 12 months of free updates, and handover documentation covering the framework choices so your team can own the codebase.
✓ step 06 complete

Why teams choose us for Cross-platform work
We are fluent in every major approach, which is exactly why we do not push only one.
Framework-agnostic advice
We ship Flutter and React Native in production and assess KMP and PWA options honestly. Our recommendation is driven by your product and team, not by which skill set we happen to be selling this quarter.
Senior engineers in each camp
Dedicated Flutter engineers, dedicated React Native engineers, and native Swift and Kotlin capability behind them, so the native escape hatches are engineered, not improvised.
AI-augmented delivery
AI tooling accelerates test generation, refactoring, and review across all our cross-platform projects while senior engineers own architecture. One codebase, faster cycles.
Parity by decision, not accident
Platform differences are decided and documented each sprint, which kills the slow divergence that makes cross-platform apps feel abandoned on one platform.
Migration experience
We have moved products off dead frameworks and between approaches without taking them out of the stores, using incremental strategies that keep revenue running.
Track record since 2010
9,000+ projects delivered and 3,900+ apps published across 25+ countries, with cross-platform builds at consumer scale among them.
