Flutter renders its own UI, so a product grid, a promotion screen, or a custom checkout looks and behaves identically on iOS and Android from one codebase, typically at 30 to 40 percent less than building two native storefronts. It compiles to native code, which keeps scrolling smooth on the mid-range Android devices where much of retail traffic actually happens. The platform-specific parts — Apple Pay and Google Pay sheets, some payment provider SDKs — are reached through platform channels, which is routine but real engineering work.\"},{\"title\":\"How much does it cost to build an e-commerce app?\",\"text\":\"Our published e-commerce tier covers catalog and search, cart and checkout, payment gateway integration, order tracking, reviews, and inventory management over four to six months — the exact range is on this page and on the Flutter app development page rather than behind a sales call. Multi-vendor platforms and branded app fleets price as enterprise work. What moves the number is the count of payment methods and markets first, and how much catalog machinery your backend already provides second.\"},{\"title\":\"Can a Flutter app use Apple Pay and Google Pay?\",\"text\":\"Yes, through platform channels backed by each platform's own payment SDK, presented as the native payment sheet users recognize. Native sheets convert measurably better than typed card forms on mobile, so we wire them alongside the provider's card flow rather than instead of it. Raw card entry stays inside the payment provider's SDK, which keeps your app out of PCI scope wherever the provider allows it.\"},{\"title\":\"Can Flutter handle a large product catalog?\",\"text\":\"Yes, with the right architecture: the catalog lives on the server and the app holds a paginated window over it, with search on the backend, images sized and cached per screen, and product pages that render instantly from cached list data while details load behind them. The failure mode is not Flutter — it is treating a hundred-thousand-item catalog as a list to fetch. We have shipped the browsing mechanics at marketplace scale, with multi-currency pricing and location-filtered feeds.\"},{\"title\":\"We already sell through a website. Do we need an app?\",\"text\":\"Not always, and we will say so when a well-built mobile web experience is the honest answer. An app earns its budget through the retention surface a website does not have: push notifications for offers and order updates, a home-screen icon, native payment sheets, and loyalty mechanics that reward returning. If most of your revenue is repeat customers, that case is usually strong; if it is one-off search traffic, spend on the web first — we build that too.\"},{\"title\":\"Can one codebase power several branded shop apps?\",\"text\":\"Yes — that is our most direct commerce credential. One Flutter codebase we built produces more than fifteen fully branded consumer apps plus a merchant app, with an admin panel that launches a new brand without engineering work. The store-policy trap is Apple guideline 4.2.6, which exists to reject fleets of near-identical apps, and a white-label platform has to be designed to pass it from the start.

The business case is structural: one codebase means one team, one release train, and every feature built once — which is why a Flutter build typically costs 30 to 40 percent less than two native apps, with the gap widening over the product's life as maintenance compounds. The engineering case is that Flutter compiles to native code and draws its own UI, so it avoids both the performance penalty of hybrid frameworks and the platform drift of maintaining two implementations.\"},{\"title\":\"How much does Flutter app development cost?\",\"text\":\"Our published tiers run from $15,000 to $30,000 for an MVP, $30,000 to $60,000 for a full business app, $50,000 to $90,000 for an e-commerce product, and from $90,000 for enterprise work — the exact ranges are in the pricing section of this page rather than behind a sales call. What moves the number is scope first and integrations second. The full breakdown of what drives the figure, including the costs teams forget to budget, is in our guide to Flutter app development cost in 2026.\"},{\"title\":\"How long does it take to build a Flutter app?\",\"text\":\"An MVP takes two to three months from kickoff to a live store listing. A full business app runs three to five months, and an e-commerce or enterprise build four to six or more. The calendar is rarely consumed by the code: payment flows that appear mid-project, design rounds, third-party API access, and the store submission cycle are where timelines actually move. Our phase-by-phase breakdown is in How Long Does It Take to Build a Flutter App.\"},{\"title\":\"Can Flutter apps perform as well as native apps?\",\"text\":\"Yes. Flutter compiles ahead of time to native ARM code and renders through its own graphics engine, so animations hold 60 frames per second — 120 on supported displays — without the bridge overhead hybrid frameworks carry. Production apps like Google Ads, Alibaba, and BMW's vehicle app run on Flutter, and our own ExtraETF holds its frame rate under live streaming market data. The honest caveat is that performance is a property of the engineering, not the framework: unscoped widget rebuilds will drop frames in Flutter exactly as leaked observers will in Swift.\"},{\"title\":\"How is Flutter different from React Native?\",\"text\":\"Flutter compiles to native code and draws its own UI through its rendering engine; React Native bridges to each platform's native components. In practice that gives Flutter better performance headroom, pixel-identical UI across platforms, 90 to 95 percent code reuse against 70 to 85 for React Native, and six supported platforms including desktop. React Native remains a credible choice for teams already deep in React. Our full comparison, including where React Native wins, is in Flutter vs React Native in 2026.\"},{\"title\":\"Is Flutter a good choice for web and desktop apps?\",\"text\":\"With qualifications. Flutter web is strongest for app-like experiences — dashboards, portals, tools behind a login — where its canvas rendering is an asset rather than a cost; for content sites that live on SEO and instant first paint, a conventional web stack is the better tool, and we say so even though we sell both. Desktop support for Windows, macOS, and Linux is production-ready and shines for internal tools and companion apps sharing a mobile codebase.\"},{\"title\":\"Can you take over or rescue an existing Flutter app?\",\"text\":\"Yes — some of our best-documented work started that way, including a live telehealth product we stabilised while it stayed in production. A takeover starts with an audit of the codebase: architecture, state management, test coverage, and the specific symptoms that prompted the call. You get a written findings report and a sequenced plan before any rebuild conversation happens, because sometimes the answer is two weeks of fixes rather than a rewrite — and when it is, we say so.\"},{\"title\":\"Do you build the backend as well as the app?\",\"text\":\"Yes. ExtraETF runs on a Go backend we built for real-time market data fan-out; Formtastic's platform includes backend and web alongside the apps; and for MVPs we deliberately reach for managed backends like Firebase when writing one from scratch would be spending your budget on plumbing. The choice between custom and managed is an engineering decision we make openly during scoping, because it moves both the price and the timeline.\"},{\"title\":\"Will Flutter still be a safe bet in five years?\",\"text\":\"As safe as bets get in this industry. Flutter is developed in the open by Google, ships regular stable releases, powers Google's own revenue-critical apps like Google Ads, and has one of the largest cross-platform communities and package ecosystems. No framework choice is risk-free — which is why the more durable insurance is code quality: a well-structured Flutter app with clear module boundaries keeps its business logic portable no matter what the industry does next.\"},{\"title\":\"Which industries do you build Flutter apps for?\",\"text\":\"Our deepest vertical work is in fintech — investing, banking, and payments products — and healthcare, including telemedicine, each with its own dedicated service page covering the compliance and engineering specifics. Beyond those we have shipped marketplaces, social and community products, loyalty platforms, and AI-driven consumer apps. What transfers across all of them is the production discipline: real-time data handling, offline behaviour, accessibility, and store review requirements.\"},{\"title\":\"How do we start a project with you?\",\"text\":\"Tell us what you are building through the contact form, including whatever exists today — a spec, a prototype, an app already in the stores.
