"One codebase, two apps, half the price." That line, or something close to it, is on most pages selling Flutter, and it's why most estimates of Flutter app development cost start from the wrong number. A production Flutter app costs $60,000 to $150,000 for a first version. That means auth, a real backend, payments, push notifications, an admin panel and approval in both stores, built by a senior team of three or four over three to five months. The low end is a focused app on a managed backend. The high end is a two-sided product with payments and several native integrations. Compared with building native iOS and Android separately, Flutter saves roughly 20 to 35 percent. That's real money, but it's well short of half.
The range comes from simple arithmetic. A senior nearshore team at $50–99 an hour costs about $20,000 to $55,000 a month, depending on headcount and seniority mix, and a real V1 takes three to five months. The $10,000–$25,000 Flutter quotes you'll also find are real, but they pay for something else: a reskinned template or a UI prototype with no backend behind it. Our mobile group builds in native Swift, native Kotlin and React Native, so we price the cross-platform decision against the alternatives. We have no framework to defend. From that angle, the consensus on Flutter pricing gets about half of it right. Here it is, one claim at a time.
Claim One: One Codebase Means Half the Cost
Flutter shares the client app, and the client app is only part of the bill. In a typical V1, the iOS and Android code together take maybe 40 to 50 percent of the hours. The rest goes to the backend and API, the admin panel, design, QA, release management and project coordination. None of that changes when you pick Flutter. A server that handles bookings, payouts or claims costs the same whatever draws the buttons.
Flutter also doesn't turn two client builds into one. It turns them into about 1.2. The extra 0.2 is the per-platform work that never goes away: permission flows that behave differently on each OS, push notifications set up separately through APNs and Firebase Cloud Messaging, two store reviews with different rejection habits, design tweaks where one platform's conventions win, and device testing on real hardware for both. Take a $150,000 native budget: $50,000 for backend and admin, $35,000 each for iOS and Android, and $30,000 for design, QA and delivery. Rebuilt in Flutter, it comes to roughly $50,000, plus $42,000 for the shared client, plus $25,000 for design, QA and delivery, which is about $117,000. That's a saving of about 22 percent. QA drops less than people expect, because you still test on a matrix of iPhones and Android devices.
Claim Two: The Hourly Rate Sets the Price
Rates vary about twofold between credible senior teams. Scope varies five to tenfold for what the founder would call the same app. The framework decision moves the total by 20 to 35 percent. Scope moves it by multiples.
Meal4U shows this clearly. We came into a stalled build that the previous team had failed to deliver. Before writing new code, we spent a week pulling the scope apart and re-estimated it about ten times, cutting 30 to 50 percent on each pass until we reached the smallest product that could actually ship. The cuts compound: three passes at 30 percent leave about a third of the original estimate. The framework never came up as a lever, because nothing it could do was anywhere near that size. When a Flutter quote looks expensive, the feature list is almost always the reason, and the rate or the framework rarely is.
Claim Three: Flutter Works for Any App
Flutter draws every pixel with its own rendering engine. That's why its UI looks the same on both platforms, and it's also where the cost structure changes. Anything that reaches into the operating system goes through plugins or platform channels. That includes background location, Bluetooth Low Energy, HealthKit and Health Connect, CallKit, and in-app purchases once you get past the happy path. If a solid plugin exists, you pay little extra. If the plugin is thin, abandoned or missing, someone writes Swift and Kotlin anyway, and the project now needs three languages instead of one.
Some surfaces can't be built in Flutter at all. iOS home-screen widgets are built with WidgetKit and SwiftUI. Apple Watch and CarPlay experiences are native work too. An app that needs three or four of these deep integrations can use up the entire cross-platform saving, and it ends up with a codebase that's harder to staff than either native option. So the integration list matters more to the cost than the screen count. It's the first document worth writing before anyone quotes a number.
Claim Four: Once It Ships, the Cost Is Behind You
A mobile app needs regular work just to stay in the stores. Apple and Google ship major OS releases every year. Google Play raises its minimum target API level on a yearly schedule and eventually hides apps that don't keep up. Flutter adds its own layer: SDK upgrades that occasionally break things, and a plugin ecosystem where many important packages on pub.dev are maintained by one or two people. When the plugin your payments or maps flow depends on stops getting updates, the choice is to fork it or rewrite that part.
A reasonable planning figure is 15 to 20 percent of the original build cost per year. A $100,000 Flutter V1 means $15,000 to $20,000 a year before any new features. None of that is specific to Flutter. Native apps need the same OS-release work. But the "one codebase" pitch tends to leave maintenance out, and plugin dependency is a maintenance risk native builds carry less of.
Claim Five: Flutter Developers Are Cheaper and Easier to Find
Senior Flutter engineers charge about what senior mobile engineers charge everywhere else. The real difference is the size of the talent pool and what else those engineers can work on. Outside Flutter, Dart has almost no mainstream use, so a Flutter team can't easily move onto your web product, and your React and TypeScript web team can't move onto the mobile app. React Native lets a company with a React web product share engineers, patterns and some business logic across both. Flutter makes mobile a separate team.
In year one this barely registers. It shows up in year two, when you're hiring a replacement, or when the web team is idle while the mobile backlog grows. It also affects quality. The cheapest Flutter quotes usually leave out code review, and in a single shared codebase an unreviewed shortcut breaks both platforms at once. Our rule that a second senior engineer reviews every pull request before merge costs hours up front and saves a lot more in rework. That applies to any framework, but a shared codebase is where skipping it costs the most.
When Flutter Is Worth the Money
Flutter earns its place when several conditions hold together. You need both platforms from launch, because a meaningful share of your users are on Android, as they are across much of Europe, Latin America and Asia. Your UI is custom and brand-heavy, and you want it to look identical on both platforms, which is exactly what Flutter's own renderer is good at. Your device needs are standard: camera, maps, push, Stripe payments, social login. And you have no React web team whose skills you'd otherwise want to reuse. Under those conditions, the 20 to 35 percent saving is real, and a V1 aimed at learning from users can spend it on two or three more iteration cycles. At that stage, extra iterations are usually worth more than platform polish.
When It Isn't
It doesn't pay off when one platform is enough. For an iOS-first consumer launch in the US, one native iOS app costs less than a Flutter app for two platforms, and Android can wait until there's traction to justify it. It doesn't pay off when the product depends on the operating system, like fitness apps built on health data, logistics apps built on background location, or hardware companions built on Bluetooth. There, the plugin layer becomes the most expensive part of the project. It doesn't pay off when you already run a React web product, because React Native gives the same cross-platform saving and lets the two teams share people. And it doesn't pay off when feeling native is part of what users are paying for, as with professional tools whose users expect every system convention to behave exactly as it does elsewhere on their phone.
The Straight Answer
A production Flutter V1 costs $60,000 to $150,000. It runs about 20 to 35 percent below building native iOS and Android separately, and it costs 15 to 20 percent of the build every year after launch. The factors that move the number, in order of size, are scope, the number of platforms you actually need at launch, how deep the native integrations go, and last, the hourly rate. Most budget conversations begin with the rate and the framework, which are the two smallest factors on that list.
That order is why we start with a free discovery week and hold off on the quote. During that week, scope gets pulled apart, the native integration list gets written down, and the choice between Flutter, native and React Native gets made against your actual features instead of a slogan. After that, a paid pilot with no lock-in puts a real team on the build and gives you a measured monthly cost before you commit to the full V1. The work then runs in two-week sprints with daily standups. If you have a feature list and a budget figure, send us both, and the discovery week will show which of the two has to change.
