Cross-platform apps

One codebase, every screen. No compromise.

Flutter, React Native, Compose Multiplatform. iOS + Android + Web + Desktop from a single codebase. Native bridges for Apple Intelligence and Gemini Nano when relevant. Time-to-market halved.

The context

Why cross-platform is back in 2026.

Five years ago, choosing Flutter or React Native meant accepting a compromise on native quality. In 2026, that compromise dissolved. Flutter 3.27 reaches native 120fps on iOS and Android. React Native New Architecture (Fabric + TurboModules) removes the slow JS bridge. Compose Multiplatform shares Kotlin UI between Android and iOS without perceivable degradation.

The economic argument is massive: a team of 3 developers ships in 4 months what required two native teams × 6 months (so 4× more expensive) in 2021. For a startup or B2B product where premium iOS UX is NOT the differentiator, cross-platform is now the default rational choice.

Our approach: we look at your product, team, UX constraints. If premium iOS quality is a business argument (Apple Watch, Vision Pro, central Apple Intelligence), we recommend native. Otherwise, cross-platform with Flutter or React Native based on ecosystem, with native modules on critical zones (payment, camera, on-device AI).

The frameworks

Four options, we choose together.

No dogma. Each framework has its sweet spot. We help you choose based on your product, team and constraints.

Flutter

by Google

Most mature for app + web + desktop.

PROS

  • + Native performance (Skia → Impeller)
  • + iOS + Android + Web + Windows + macOS + Linux
  • + Legendary hot reload
  • + Rich pub.dev ecosystem

CONS

  • − Dart: less common language
  • − Heavier iOS bundle (15-25 MB)
  • − Custom look (little iOS native)

Best for B2B apps, fintech, dashboards, multi-platform productivity.

React Native

by Meta

Universal JavaScript ecosystem.

PROS

  • + JS/React skills already widespread
  • + Native iOS and Android look by default
  • + New Architecture (Fabric, TurboModules)
  • + Expo to deploy in days

CONS

  • − Performance < Flutter on heavy animations
  • − Native bridges sometimes needed
  • − Heterogeneous lib ecosystem

Best for Consumer apps with JS team, fast MVPs, moderate native integrations.

Compose Multiplatform

by JetBrains

Kotlin for iOS + Android + Desktop.

PROS

  • + True native compiled Kotlin
  • + Excellent performance everywhere
  • + Share business logic Android ↔ iOS
  • + Desktop (Win, Mac, Linux) supported

CONS

  • − iOS UI less mature than Compose Android
  • − No mature web support
  • − Smaller community

Best for Android-first teams wanting to add iOS without rewriting everything.

Kotlin Multiplatform

by JetBrains

Business sharing only, native UI.

PROS

  • + 100% native UI (SwiftUI + Compose)
  • + Share only networking/DB/business
  • + No iOS/Android UX compromise
  • + Progressive integration possible

CONS

  • − Non-trivial initial setup cost
  • − Not all-in-one (separate UI)
  • − Native Kotlin learning curve

Best for Apps where premium native iOS UX is non-negotiable but you want to avoid coding business logic twice.

What we build

Six cross-platform app profiles.

From startup MVP to multi-OS enterprise deployment, profiles we ship.

Consumer startup MVP

From concept to App Store in 8-12 weeks.

To validate a product idea without committing 2 native teams. Flutter or React Native, design adapted iOS and Android, Stripe / RevenueCat for monetisation, Firebase to start. If the product takes off, we can migrate to native later.

iOSAndroid

Multi-role B2B app

One codebase for technicians, sales, admin.

When your SaaS needs a phone + tablet + desktop app for different user profiles. Flutter by default (best multi-platform), responsive layout, offline-first with sync, enterprise SSO integration.

iOSAndroidWebWindows

Multi-platform consumer app

Phone + tablet + web from one team.

Productivity, lifestyle, education. Flutter or React Native + Next.js for web. Synced cross-device accounts, cross-platform push notifications, IAP iOS/Android/Web (Stripe), unified analytics.

iOSAndroidWeb

Desktop app (Win + macOS + Linux)

Pro tool that runs everywhere.

Desktop apps for creative, coding, engineering pros. Flutter or Tauri (Rust + web). Native performance, filesystem, memory, GPU access. Distribution via Microsoft Store, Mac App Store, Snap, AppImage.

WindowsmacOSLinux

Fintech / banking app

Max security, shared code.

For fintechs avoiding double security certification cost. KMP (shared business logic + native UI) often wins: one-time certification of network/crypto layer, but iOS and Android UX stays native.

iOSAndroid

Enterprise MDM app

Fleet deployment 10k+ users.

Internal apps for iPhone (sales) + Android (field) + tablet (admin). Flutter, MDM deployment (Jamf, Intune), SSO, offline-first, private distribution Apple Business Manager + Managed Google Play.

iOSAndroidTablet

Our approach

Four steps, from stack choice to deployment.

We start by recommending the best stack for YOUR case. Then we ship in parallel on all target platforms.

01

Stack choice (1 week)

Audit your constraints: budget, team, target platforms, premium iOS UX criticality, native integrations needed, GDPR. Quantified comparison Flutter vs React Native vs KMP vs native. Argued recommendation.

▸ Stack recommendation + budget estimate × 4 scenarios

02

Architecture & design (2-3 wks)

Multi-platform architecture, adaptive Figma design (mobile + tablet + desktop based on targets). Code share strategy (% shared vs native), native bridges identified, CI/CD pipeline for all targets.

▸ Architecture + Figma mockups + shared design tokens

03

Parallel development (6-12 wks)

Incremental build on ALL platforms in parallel. Internal testing (TestFlight + Play Internal + Vercel Preview) every sprint. Automated tests on each target. Regular performance audit.

▸ Functional app on all platforms + tests

04

Multi-store submission (2 wks)

App Store + Play Store + Web + Microsoft Store + Mac App Store based on targets. Coordinated release dates for marketing coherence. ASO optimised per store.

▸ Apps live on all stores + ASO report + 30-day guarantee

Measurable guarantees

Four contractual commitments.

≥ 60fps

Native performance

60fps minimum on transitions, 120fps on iPhone Pro and Pixel Pro. Profiling tests on real devices before delivery.

≥ 70%

Shared code

At least 70% of code shared between platforms (often 85-95% with Flutter). The rest = native bridges and UX adaptations.

AA

Accessibility everywhere

VoiceOver (iOS), TalkBack (Android), desktop screen readers. WCAG AA on web. Tests on the 3 environments.

30d

Bug guarantee + 1 OS update

30-day bug guarantee. Major iOS or Android update within 6 months? Free patch.
