QalbIT uses Flutter to design and build cross-platform mobile apps that feel close to native on both iOS and Android. We focus on clear user journeys, reliable offline behaviour where needed and clean integration with your backend so the app is maintainable long term.

Flutter development overview
We adopt Flutter when you want to deliver high-quality mobile apps for both iOS and Android without running and funding two completely separate codebases.
For some edge cases (for example very device-specific or graphics-heavy apps) we may still recommend native – otherwise Flutter is often a strong default for multi-platform products.
What we build with Flutter
We focus Flutter on mobile applications where user experience, performance and long-term maintainability matter.
Customer apps
B2B and B2C apps for customers – bookings, orders, accounts, dashboards and self-service workflows on iOS and Android.
Internal tools
Apps for internal teams or field staff to capture data, manage tasks, inspections, deliveries or service visits on the go.
Companion apps
Flutter apps paired with existing SaaS/web platforms to provide mobile access to key features, notifications and dashboards.
MVPs
Focused MVPs to validate new ideas with real users quickly, with a clear path to grow into a production-ready mobile product.

Discuss your Flutter app scope →How Flutter projects work with QalbIT
Our Flutter process is designed to reduce surprises around UX, integrations, timelines and app store approvals.
1–2 weeks
Understand your users, key journeys and backend systems. Map which parts of your product need to be in the app and which can stay on web.
Key outcome: User journeys, high-level information architecture and a realistic first release scope.
2–4 weeks
Define navigation, screen layouts, key components and state management approach, aligned with your brand and backend APIs.
Key outcome: Approved UX/UI flows and a technical blueprint for the Flutter app.
4–10+ weeks (scope-dependent)
Build Flutter screens and components, wire them to your APIs, implement authentication, validation, offline behaviour and error handling.
Key outcome: Working Flutter app builds for iOS and Android in testing or staging environments.
2–4 weeks
Functional and device testing, performance tuning, crash monitoring setup and guiding you through App Store and Play Store submission.
Key outcome: Approved app releases in stores or ready for phased rollout and internal distribution.
Ongoing, month-to-month
Support for OS updates, bug fixes, small improvements and new features via retainers or dedicated teams.
Key outcome: A Flutter app that keeps pace with your users, roadmap and platform changes.

Walk me through this Flutter process for my app →Where Flutter is usually the right fit
Most of our Flutter projects are tied to serious products – customer apps, internal tools and SaaS platforms – not just brochure apps.
For SaaS and product teams
When you already have a web portal or SaaS product and want a mobile app so customers can access key features anytime.
For Operations, logistics and service teams
When on-the-ground teams need reliable mobile tools for data capture, checklists, site visits, deliveries or inspections.
For Founders and startups
When you are validating a new mobile-first product and want to reach both iOS and Android users with one initial build.
For Teams with legacy apps
When existing hybrid or dated mobile apps feel slow or hard to maintain, and you want a cleaner Flutter replacement.

Making the app reliable in real-world usage.
Keeping the app healthy over time.
If you already have a backend, we integrate with it. If not, we usually pair Flutter with Laravel or NestJS APIs designed specifically for your product.

Contact our expertsFlutter is a cross-platform mobile framework by Google that lets you build iOS and Android apps from a single codebase. It provides near-native performance, a rich set of UI components and a strong ecosystem, making it ideal when you want consistent experiences across platforms without maintaining two separate native apps.
We use Flutter to build customer-facing apps, internal and field operations apps, companion apps for existing SaaS or web platforms and focused MVPs to validate new product ideas. Many of these apps integrate deeply with backends, payment gateways and other systems rather than being simple brochure apps.
Flutter gives you a single codebase for iOS and Android, which usually reduces development and maintenance effort compared to two fully separate native apps. For most business, SaaS and workflow-driven applications, Flutter’s performance and UX are more than sufficient. For very specialised use cases – such as advanced 3D games or extremely hardware-dependent features – fully native code may still be the better choice.
Yes. In many projects we connect Flutter apps to existing backends and APIs built in Laravel, NestJS or other stacks. We review your current API design and authentication, then integrate the app with those endpoints, adding or adjusting APIs only where necessary to support mobile use cases cleanly.
We can. We usually begin with a code and architecture review to understand how the current Flutter app is structured, any technical debt and the state of integrations. Based on that, we stabilise critical issues, set up crash monitoring if needed and then plan ongoing improvements and new features.
Timelines depend on scope, design depth and integrations. As a rough guide, a focused Flutter MVP that covers a clear set of user journeys can often be delivered in 8–14 weeks after discovery. Larger, feature-rich applications or complex integrations will take longer and are usually delivered in phases.
We design Flutter apps with real-world usage in mind – optimising critical screens, reducing unnecessary API calls, caching important data and implementing offline-friendly flows where required. We also handle network errors gracefully with clear messages, retries and fallbacks so users are not stuck on a blank screen.
Yes. We prepare builds, app metadata, screenshots and release notes, and guide you through using your Apple Developer and Google Play Console accounts. We also help set up internal testing tracks, review workflows and a repeatable release process for future updates.
For clearly scoped Flutter projects we typically work on a fixed-price, milestone-based model. For evolving products or long-term roadmaps, we usually recommend a monthly or dedicated team engagement. In both cases we provide transparent estimates tied to scope, complexity, design and expected support after launch.
