Flutter App Development Company

A Flutter app usually costs from about $5,000 for a simple MVP to roughly $30,000 to $80,000 for a full business app, with enterprise builds running higher. The range depends on the number of features, integrations, and design work.

Because Flutter uses one codebase for iOS and Android, it typically costs 30 to 40 percent less than building two native apps. We give a fixed price band after a short scoping call, so you are not guessing.

Most Flutter apps take about 1 to 3 months for a simple app, 3 to 6 months for a mid-complexity app, and 5 to 12 months for a complex enterprise build. A single codebase means iOS and Android ship together, not one after the other.

The timeline depends on the feature set, integrations, and how ready the design and content are. We commit to a schedule at the end of scoping and show working builds each sprint.

Choose Flutter when you want pixel-consistent design, strong animation and performance, and a path to web and desktop from the same codebase. Choose React Native when your team already lives in JavaScript and React.

Both are mature in 2026 and both save 30 to 60 percent against separate native builds. The bigger cost factor is the framework your team knows. Our team builds in Flutter and native iOS and Android, so we recommend the fit for your product, not the tool we prefer.

Flutter is Google's open-source toolkit for building apps from a single codebase that runs on iOS, Android, web, and desktop. It uses the Dart language and draws its own UI, so apps look and perform consistently on every device.

Businesses use it to ship to two platforms at once, cut cost, and keep one team instead of two. Global apps from Google, Alibaba, and BMW run on Flutter, which is why it is a safe enterprise choice.

Yes. We migrate native iOS and Android apps to Flutter in stages, mapping your current architecture, rebuilding screens as Flutter widgets, and moving features across without breaking the live app.

Migration makes sense when you are maintaining two native codebases and want to move to one. We start with an audit and a migration plan so you can see the effort and payoff before committing.

Yes. You can hire dedicated Flutter developers from CISIN on a full-time or monthly basis, working as an extension of your team. Our developers work across Flutter and native Android and iOS.

This suits teams that need to add senior Flutter capacity fast without a full agency engagement. We match developers to your stack and timezone needs.

We build custom apps, eCommerce apps, progressive web apps, and enterprise apps, and we handle Flutter migration, maintenance, and project rescue. Our shipped work includes taxi-booking, messaging, and trading apps.

We work across industries including education, finance, healthcare, gaming, retail, and logistics, matching the build to the compliance and scale each one needs.

Yes. Flutter is well suited to an MVP because one codebase gets you to both app stores faster and cheaper, and the hot-reload workflow lets you change features quickly during early testing.

For a startup that needs to validate an idea on a budget, a Flutter MVP reaches iOS and Android users at once, which is hard to justify with two separate native builds.

We follow test-driven deployment on every build, run testing across iOS and Android, and work under CMMI Level 5 process maturity and ISO 9001 quality management. We sign an NDA and assign all IP to you.

For regulated products we align to the security standards the sector requires, and we can walk you through our review and release process before the project starts.

Yes. We offer ongoing maintenance, updates, and new-feature work after launch, and we also take over Flutter projects that another team started or left unfinished.

Post-launch support typically runs at a predictable monthly rate, so you can plan for OS updates, fixes, and improvements without surprises.

Flutter builds mobile, web, and desktop from one codebase. We can package a mobile app as a progressive web app so it also runs in the browser, and target desktop where it fits your product.

This is one of Flutter's advantages over mobile-only frameworks: the same code can reach more surfaces as your product grows.

CISIN has built software since 2003, with a 1000-plus in-house team, a 4.9 out of 5 GoodFirms rating across 42 reviews, and shipped Flutter apps across taxi, messaging, and trading. You get a Flutter and native team under one roof.

We are transparent about cost and timeline, work under ISO and CMMI process standards, and sign an NDA with full IP assignment, so you own everything we build.
