Flutter App Development

Flutter App Development Company for iOS & Android Apps

One codebase. Two platforms. Shipped in weeks, not months. Most agencies still quote you separately for iOS and Android, then take three to six months to deliver. CueBytes does it differently. We're a Flutter app development company that ships cross-platform mobile apps in 2 to 4 weeks, at a fixed price, with full source code of yours from day one. RentKeep went from concept to App Store in 6 weeks as an offline-first Flutter app. Voice Clone AI launched on iOS and Android with 500+ downloads. PaveQuote shipped to the Play Store in 4 weeks. Real apps. Real timelines. Real founders we still work with today.

What's Included

Flutter App Development Services What's Actually Included

We don't hide deliverables behind discovery calls. Here's exactly what you get.

One Flutter Codebase, Two Platforms

Native-feeling iOS and Android apps from the same code. As a Flutter development company, we build at roughly half the cost of two separate apps with consistent UI across both.

Custom UI/UX in Figma First

Our designer builds your screens before any code is written. You approve every pixel before development begins.

Firebase, REST, GraphQL, Payments

Real-time databases, authentication, push notifications, Stripe or in-app purchases, any third-party API your app needs.

Full App Store and Play Store Submission

We handle certificates, screenshots, store descriptions, and review follow-up. If Apple or Google rejects something, we handle the resubmission cycle.

AI-Accelerated Development

We use AI tools internally to ship roughly 5x faster than traditional Flutter agencies. Speed comes from process, not corner-cutting.

30-Day Post-Launch Support

Free bug fixes for the first month after launch. Maintenance retainers available after that if you want ongoing work.

Process

Our Flutter Build Process (Week by Week)

Week 1 Discovery, Scope, Design

We jump on one call and lock the scope. You walk away with a fixed price, a fixed delivery date, and 5 to 8 Figma screens designed. No hourly billing. No surprise change orders.

Week 2 Core Build and Staging

Authentication, main user journey, and payments built. By the end of week 2, you click through a working version on staging. Daily updates land in Slack or WhatsApp.

Week 3 Polish and Store Prep

Edge cases handled. App Store and Play Store screenshots prepared. Listing copy written. Quality pass on real iPhones and Android devices.

Week 4 Submission and Handover

We submit the app to both stores on your behalf. Then we hand over: GitHub repo, all credentials, design files. Your 30-day support window starts. You own everything.

Flutter Mobile App Development Services Built for Speed

Flutter mobile app development services from CueBytes are designed for founders who need iOS and Android apps shipped fast without compromising on quality. Single codebase, native performance, polished UI on both platforms.

Why Flutter Wins for Most Mobile Apps

Choosing the right framework matters more than founders realize. Here's the honest comparison from our team's experience shipping apps in Flutter, React Native, and native Swift/Kotlin over the last few years.

Versus native iOS + Android (Swift + Kotlin). Two separate codebases means two teams, two timelines, two bug-fix cycles. Flutter gives you one team and roughly half the build time. For 90% of apps, the performance difference is invisible to users.

Versus React Native. Flutter wins on UI consistency. React Native apps tend to look slightly different on iOS versus Android because they bridge to native UI components. Flutter renders its own UI on a custom engine, so your app looks identical everywhere. Flutter also handles complex animations and custom designs better.

Where Flutter excels. MVPs, content apps, social apps, e-commerce, fintech dashboards, marketplaces. Anywhere you need a polished UI fast on both platforms.

Where Flutter is not the right call. Heavy ARKit features, deep CallKit integration, console-grade gaming. We will tell you on the discovery call if your idea genuinely needs native, and recommend you go that route instead. Honesty saves us all time.

Pricing

Flutter App Development Cost Transparent Pricing

Most Flutter mobile app development services hide pricing behind a schedule a call button. We don't, because tire-kickers waste everyone's time and serious founders deserve straight numbers.

Simple Flutter App (5-7 screens)

$4,500 - $6,500

Mid-Complexity App (10-15 screens, integrations)

$6,500 - $10,000

Complex App (custom features, backend, multiple integrations)

$10,000 - $18,000

Every package includes Figma design, full Flutter build, backend setup if needed, App Store and Play Store submission, and 30 days of post-launch support. No hourly billing creep. No retainer required. If your scope genuinely needs more, we will quote a custom range on the discovery call. We would rather lose a project than misquote it.

Why CueBytes

Why We're a Top Flutter App Development Company

We work with founders across the US, UK, Nigeria, and Asia. Here's what makes the difference.

30+ Flutter apps shipped. Real apps on real stores, not concept demos. Many of our US clients found us specifically because they wanted the best Flutter app development company that ships fast without the typical agency overhead. We're consistently ranked among top Flutter app development companies for speed and pricing transparency.
Senior-only team. Every developer at CueBytes has 5+ years of Flutter experience. We don't subcontract to junior offshore developers. The person you meet on day one writes your code.
Daily updates, not weekly status meetings. You get a Slack or WhatsApp message every working day with what shipped, what's next, what's blocked. If something slips, you hear about it the day it slips.
Pakistan-based, US-friendly timezone. Our overlap with both US and EU business hours is workable. We provide Flutter app development services in the USA, UK, and globally, working remotely with founders worldwide. Most US clients are surprised how seamless this is once they try it.
You own everything. Source code, design files, credentials, store accounts. All yours after delivery. No vendor lock-in. No "we host your repo" arrangements. No licensing fees.

What We Won't Build

Most agencies say yes to everything. We don't.

We won't take a 6-month Flutter project. That's not our model. If your scope genuinely needs that long, we will tell you on the discovery call and recommend you bring on a long-term team instead.

We won't build something just because Flutter is trendy. If your app needs heavy native iOS or Android features that Flutter handles poorly, we will say so and point you to a native development shop.

We won't quote a price we can't honor. Fixed price means fixed price. If we underestimate scope, that is our problem to solve, not yours.

This honesty has cost us projects. It's also why founders who work with us once tend to come back for their next app. If you would rather Flutter developer talent on a dedicated retainer instead of a fixed-price project, we offer that too. As a professional Flutter app development company, we work with founders both ways see our Flutter developer service for retainer engagements.

FAQ

Frequently Asked Questions

Flutter is Google's open-source framework for building cross-platform mobile apps from a single codebase. In simple terms, Flutter app development means writing your app once and shipping it to both iOS and Android, with native-feeling performance on each platform. It cuts build time and cost roughly in half compared to building separate native apps.

For most use cases, yes. Flutter handles content apps, social apps, e-commerce, fintech, marketplaces, and MVPs extremely well. The UI looks identical across iOS and Android, performance is near-native, and the build process is significantly faster. The exceptions are apps requiring deep native integrations like ARKit, CallKit, or console-level graphics.

Our Flutter app development cost ranges from $4,500 for a simple 5 to 7 screen app, up to $18,000 for complex apps with custom features and backend integrations. Most of our projects fall in the $6,500 to $10,000 range. Pricing is fixed before we start, with no hourly billing or scope creep.

Simple Flutter apps ship in 2 to 3 weeks. Mid-complexity Flutter projects take 3 to 5 weeks. Complex apps with backend, multiple integrations, and custom features run 6 to 8 weeks. Most of our clients have a working version on staging by the end of week 2, regardless of scope.

For 90% of apps, yes. Flutter renders its own UI through a custom engine, so animations and scrolling feel native. The exceptions are graphics-heavy games and apps relying on platform-specific frameworks. For typical business apps, content apps, and most consumer apps, users can't tell the difference between Flutter and native.

Yes, fully. We handle certificates, signing, screenshots, listing copy, and the entire review process. If Apple or Google rejects the submission for any reason, we handle the resubmission cycle. You don't deal with rejection emails or DUNS numbers.
