Mobile apps that feel native everywhere — and migrate forward cleanly.
Cross-platform iOS, Android, Windows, and macOS apps in .NET MAUI — plus the studio that quietly migrates legacy Xamarin codebases forward without breaking what already works.
Write once. Feel native. Move with the platform.
.NET MAUI lets a single codebase hit iOS, Android, Windows, and macOS without giving up native look-and-feel or platform-specific integrations. We've been shipping cross-platform .NET mobile apps since the Xamarin days — same disciplines, current tooling.
Cross-platform, native feel
One C# / XAML codebase compiled to genuinely native iOS, Android, Windows, and macOS binaries. No web-views pretending to be apps.
Companion to your storefront
B2B order apps, sales-rep tools, dispatch and warehouse companions — all sharing the same ERP source of truth as the storefronts we already build for you.
Offline-first patterns
Field operations rarely have perfect connectivity. We design with conflict-free local edits, queued syncs, and clean visual cues for what's pending.
Deep native integrations
BLE, NFC, camera, biometrics, push, deep linking, App Clips, Android share targets — when an integration matters, we drop into platform-native code.
Senior team
Mobile bugs are subtle. Battery, memory, threading, push reliability — the people who scope your app are the same people who ship it and stand up for the next year.
Modern release pipeline
Automated builds, signing, internal testing, App Store / Play Store deployment, crash reporting, and release-train cadence so updates aren't an event.
We migrate Xamarin codebases forward. It's a real differentiator.
Microsoft retired Xamarin in May 2024 in favor of .NET MAUI. If you're still on Xamarin.Forms or Xamarin.Native, your app is on a platform that no longer gets fixes — security, OS updates, store-policy changes — and you're competing against teams already shipping on MAUI.
We've done both sides
The same engineers who originally built apps on Xamarin are the ones now shipping on MAUI. We know exactly what changes, what breaks, and what the migration is actually going to cost.
Parallel-run validation
We migrate incrementally and run the new MAUI build alongside your existing Xamarin app against the same test traffic — so behavior parity is proved, not assumed.
Risk-managed rollout
Phased internal release → beta cohort → store rollout with kill-switch and remote config. We don't flip a switch and hope.
How we build mobile.
Stack & architecture
- Cross-platform:
.NET MAUI+C#+XAMLtargeting iOS, Android, Windows, macOS - MVVM with
CommunityToolkit.Mvvm, source-generated bindings for performance - Local data:
SQLitefor offline-first,Realmwhen sync semantics fit better - Networking:
Refit+HttpClient,Pollyfor retry / circuit breaker - DI & navigation: built-in MAUI Shell or
Prismfor larger apps - Native interop via partial classes per-platform when MAUI abstractions aren't enough
Native integrations
- BLE / NFC for warehouse, retail, and field ops
- Camera, ML Kit / Vision for barcode & document scanning
- Biometric auth (Face ID, Touch ID, Windows Hello)
- Push notifications via APNs + FCM with quiet-hours and segmented delivery
- Deep linking, universal links, App Clips, share targets
- Background sync, geofencing, and platform-appropriate scheduling
Offline-first patterns
- Local-write, server-confirm with optimistic UI and clear pending-state cues
- Conflict resolution: last-writer-wins for low-stakes, custom merges for orders / quotes
- Queued operations with persistent retry and backoff across app restarts
- Bandwidth-aware sync (Wi-Fi-only large media, foreground-only ERP catalog refresh)
- Diagnostic export so field issues are reproducible without another phone call
Quality & CI/CD
- GitHub Actions / Azure Pipelines builds for iOS + Android in parallel
- Automated signing, provisioning, and store metadata management
- UI tests on real devices via BrowserStack / Sauce Labs / Appium
- Performance budgets (cold-start, memory, battery) tracked across releases
- Phased rollouts on Play Store and TestFlight cohorts before broad release
Observability & ops
- Crash & ANR reporting via Firebase Crashlytics / Sentry / Bugsnag / Azure Monitor with deobfuscated stacks
- Structured analytics events for funnels, with consent-aware collection
- Remote config + feature flags so we can disarm a bad release without a store update
- OTA-friendly patterns within store-policy bounds (RN-style hot-fix is not it)
- Real-user network tracing to catch ERP-bridge timeouts before customers do
Security
- Secure storage via Keychain / Keystore — never SharedPreferences for tokens
- Certificate pinning where the threat model warrants it
- Biometric step-up for sensitive actions (price overrides, order approvals)
- Jailbreak / root detection for high-value B2B contexts
- OWASP MASVS controls baked into the build pipeline, not retrofitted
Common questions
Can you migrate Xamarin.Forms to .NET MAUI?
Yes — this is one of our core mobile workstreams. We’ve moved Xamarin.Forms apps onto .NET MAUI cleanly: project-file conversion, Forms-to-MAUI control mapping, custom-renderer-to-handler rewrites, and Platforms-folder reshuffling for iOS / Android / Windows / macOS heads. We don’t do a one-shot rewrite; we lift the existing app onto MAUI in branches, ship behind feature flags, and burn down platform-specific deltas one at a time so the team keeps releasing while the migration is in flight.
What about Xamarin.iOS / Xamarin.Android (not Forms)?
Same answer with more handler work. Xamarin.iOS / .Android (sometimes called “classic Xamarin”) doesn’t map 1:1 to MAUI’s single-project model the way Forms does. We typically rebuild the UI layer in MAUI handlers, keep the underlying business logic and platform-specific bindings, and bring it across in stages. Plan for a longer migration than a Forms project; budget extra time for any custom native bindings you maintain.
Is .NET MAUI production-ready for B2B?
Yes, with eyes open. We ship MAUI in production for B2B sales-rep and field-ops apps, paired with ASP.NET Core 10 backends. Strengths: shared C#, Blazor Hybrid for content-heavy screens, real iOS / Android / Windows / macOS reach. Weaknesses to plan for: pixel-perfect custom controls take more handler work than native, deep BLE / camera APIs sometimes need platform-specific code, and the supported-iOS floor keeps rising (check Microsoft’s current matrix before committing).
How long does a Xamarin → MAUI migration take?
For a mid-size Xamarin.Forms app (say, 50–150 screens with the usual handful of custom renderers): 8–14 weeks of senior-engineer work, including QA. For Xamarin.iOS / .Android: 14–24 weeks because of the handler / UI rewrite. Budget gets cleaner once we see your project file, your custom renderer count, and how much native code lives in the head projects.
