Every Screen
We build Flutter apps for teams who don’t want to maintain three codebases to reach three platforms. iOS, Android, and web, from one team, with one person to call when something breaks.
Why We Build in Flutter
Flutter isn’t the only way to build a mobile app, but for most of what we get called about, it’s the right one: one codebase, near-native performance, and a UI that doesn’t feel like a compromise on either platform.
- Backed by Google and used at real scale, so you’re not betting the app on a framework that disappears in two years.
- Fully open source, so nothing about how your app works is locked behind a vendor’s roadmap.
- Written in Dart, which most developers pick up within a week if they already know an object-oriented language.
- Compiles to native code, so the app feels fast and responsive instead of like a wrapped webpage.
- It delivers high performance: fast compilation and smart graphics make your app smooth and responsive on every screen.
Most Flutter Apps Fail Beyond the First Release
A working Flutter app is not enough. Without the right architecture, performance strategy, and product thinking, apps become difficult to scale, maintain, and evolve. We build Flutter applications engineered for real users, real products, and long-term growth.
Slow and fragile development

Flutter Services, Built Around Your App
Six things people hire us for, from the first idea to the app that’s already live and needs someone watching it.
Flutter App Consulting
Before we write any code, we look at whether Flutter is actually the right call for what you’re building, and if it is, what the architecture needs to look like so it doesn’t fall apart at year two.

Flutter UI/UX Design
We design the interface around how people actually use the app, not around a component library we had lying around. Every screen gets checked against real user flows before it gets built.

Custom Flutter App Development
We build the app around your product, not a template. Clean architecture, state management that scales past the demo, and code your own team can maintain after we hand it off.

Flutter App Migration
Moving an existing native or hybrid app to Flutter without starting over from zero. We map what’s there, plan the cutover, and keep the app shipping while the migration happens underneath it.

API & Backend Integration
A Flutter app is only as good as what it talks to. We build and integrate the APIs behind it with real error handling, so a flaky network doesn’t mean a broken screen.

Flutter App Support & Maintenance
Someone actually watching the app after launch: crash reports, OS updates, Flutter version bumps, and the small fixes that keep it from quietly rotting.

How We Actually Build a Flutter App
Four stages, each with something real to look at before we move to the next one.
Discovery and architecture
We sit down and map out what the app actually needs to do, which platforms it has to run on, and how state should flow through it (Riverpod, Bloc, whatever fits, not whatever we used last time). Get this part wrong and you’re rebuilding the foundation six months in.
Design and prototyping
Screens get designed in Figma and wired into a clickable prototype before anyone touches a widget. It’s a lot cheaper to move a button around in a mockup than to rebuild a screen that’s already been coded.
Build in parallel
Frontend and backend get built at the same time, and you get a build to install on your own phone every week or two, not a finished app dropped on you at the end with no chance to react along the way.
Launch and handover
We handle the App Store and Play Store submissions ourselves, including the parts nobody warns you about, then hand over a codebase with documentation an actual person wrote, so the next developer isn’t guessing.
Selected Work
An offline-first inventory app for the warehouse floor
RapidStock is a B2B inventory and procurement app for businesses that manage stock across sites. We built the Flutter app and the platform behind it, connected to the client's Magento stores.

What Clients Say
Teams whose Flutter apps we’ve built or rescued, on what shipped and what it took to get there.
I have been working with Sookshum Labs directly and indirectly for over two years and very much recommend this company. We have been commissioning apps and websites for our clients in the UK using Sookshum Labs development services.
Our journey into the world of eCommerce started around eight months ago. We knew what we wanted but had no idea of how to get there. Sookshum-Labs patiently guided us and worked with us, at our speed, to build an eCommerce store we are proud of. Right from the start we found them to be professional and efficient. They did what they said they would do, on time and as agreed. We never had to push them for deliverables. Their project management was tight, and I felt we were always in control of our project. I would not hesitate to work with Sookshum-Labs again.
We have been working with Sookshum Labs for close to two years and they are outstanding. We have a fairly complex ecommerce site and regardless of the problem, Vipin and his team are fast to respond, fix, and offer solutions that have really helped our company. They are incredibly strong communicators, do excellent and fast work, and I could not recommend them more highly.
I had the pleasure of working with the Sookshum Labs on various projects (Magento – mobile development) and I recommend them for their attention to details and ability to deliver high quality web design. The team went above and beyond our expectations. I would strongly recommend them.
Wonderful experience with Sookshum Labs team. Projects were estimated accurately, team was responsive and clear, launches were smooth and they were able to accommodate some complex customizations and commerce rules. Thank you!
Moved our whole mobile and web build here after our last vendor missed the timeline and blew the budget. Three stores then, five now.
I have worked with Sookshum Labs many times now. I am always impressed by their professionalism, the high quality of their work, and their timeliness in completing work by the due date. I highly recommend them to anyone in need of engineering and development services. Keep up the great work!
Sookshum Labs team are very good at what they do. I recommend them strongly.
Talk to the practice, not a sales queue.
