WHAT WE DO

Our Flutter Developer Expertise

Cross-Platform Apps

Cross-Platform Apps

We build iOS and Android apps from one Flutter codebase — sharing business logic and UI while adapting to each platform's navigation patterns, typography, and gesture conventions.

Custom Widgets

Custom Widgets

We build custom Flutter widgets using CustomPainter, implicit and explicit animations, and shader-based effects — delivering UI that looks impossible to achieve with standard components.

State Management

State Management

We implement clean state architecture with Riverpod — separating UI state, business logic, and data access into testable, composable units without unnecessary boilerplate.

Native Integrations

Native Integrations

When Flutter plugins do not exist or are insufficient, we write platform channels in Swift/Kotlin to access native APIs — sensors, Bluetooth, biometrics, and device-specific features.

App Store Delivery

App Store Delivery

We automate the full release pipeline for both App Store and Google Play with Fastlane, including signing, build number management, and store listing metadata updates.

Performance Tuning

Performance Tuning

We use the Flutter DevTools timeline to eliminate jank — isolating expensive build and paint phases, reducing rebuild scope with const widgets, and profiling GPU usage.

Testimonials

What Our Clients Say

What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.

Frank W.

Co-CEO

Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.

Dinant V.

Co-CEO

Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.

Timur G.

CEO, Ping Proxies

Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.

Musa S.

CEO, Volume Apps

Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.

Taj S.

Product Lead, Pelago

We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.
