Key takeaways: mobile app development cost in 2026 5
What sets the price, native vs cross-platform and the real ranges by complexity.
- Complexity sets the price A simple MVP and a regulated app are both "a mobile app" but bands apart - complexity, not screen count, decides.
- Cross-platform usually wins One Flutter or React Native codebase is 30 to 40 percent cheaper than two native apps.
- Both stores, one codebase Most apps need iOS and Android - cross-platform is the economical route to both.
- Budget for maintenance Plan 15 to 25 percent of build cost per year - the app is not done at launch.
- Scoping causes overruns Most overruns come from decisions made before any code - especially an underscoped backend.
“How much does a mobile app cost?” has no single answer, because a weekend MVP and a regulated FinTech app are both “a mobile app” and sit thousands of dollars apart. What sets the number is the app’s complexity, whether you build native or cross-platform, how many platforms you ship and how much backend and integration work sits behind the screens. This guide breaks down mobile app development cost in 2026: the cost model, native versus cross-platform, honest ranges by complexity and what actually moves the budget, before you scope a build with a mobile app development partner.
In short: in 2026 a simple cross-platform app with a basic backend costs roughly $30,000 to $80,000 over 2 to 4 months. A mid-complexity app with custom design, user accounts, payments and third-party integrations runs $80,000 to $200,000 over 4 to 7 months. A complex app – multi-platform, real-time, AI features or regulated FinTech and healthcare – reaches $200,000 to $600,000 and up over 8 to 14 months. Building one cross-platform codebase with Flutter or React Native is usually 30 to 40 percent cheaper than two native apps. Plan for ongoing maintenance of 15 to 25 percent of the build cost every year – the app is not done at launch.
What goes into mobile app cost
An app price is the sum of the work, not a per-screen rate. The main buckets are product and UX design, the mobile front end (the app itself), the backend and APIs that power it, third-party integrations (payments, maps, auth, analytics, push), QA and testing across devices, and the infrastructure and app-store setup to ship it. For most apps the backend and integrations are a bigger share than people expect: the screens are visible, but the logic, data and services behind them are where the hours go. A polished design system and accessibility add cost too, and they are worth it – a cheap-looking app reads as a cheap product.
Native vs cross-platform: the biggest cost lever
The first cost decision is native or cross-platform. Native means separate iOS (Swift) and Android (Kotlin) codebases – best performance, full access to platform features, but you build and maintain two apps. Cross-platform means one codebase with Flutter or React Native that ships to both – typically 30 to 40 percent cheaper to build and maintain because the team writes it once. Cross-platform is the default for most products in 2026 and is rarely the wrong call; native earns its premium for graphics-heavy, hardware-heavy or latency-critical apps. We cover the trade-off in depth in Flutter vs React Native, but the cost rule is simple: unless you have a concrete native reason, one cross-platform codebase is the cheaper path to both stores.
Mobile app development cost by complexity in 2026
Ranges track complexity more than anything else.
Simple app: $30,000 to $80,000, 2 to 4 months. A focused MVP – cross-platform, a handful of screens, standard UI, a basic backend and login, a couple of integrations. Enough to validate an idea with real users.
Mid-complexity app: $80,000 to $200,000, 4 to 7 months. Custom design, user accounts and roles, payments, several third-party integrations, push notifications, an admin panel and a real backend. The band most funded products land in.
Complex app: $200,000 to $600,000 and up, 8 to 14 months. Multi-platform or native, real-time features, offline sync, AI or data-heavy workflows, or a regulated domain like FinTech or healthcare where security and compliance are first-class work. A mobile banking app belongs here, not in the MVP band.
What drives the cost
Within a band, the same factors move the number. Number of platforms – one or both, cross-platform or native. Backend depth – a thin API versus real-time, sync and heavy data. Integrations – each payment, mapping, identity or analytics service adds build and test time. Design – a template theme is cheap, a custom-branded design system is not. Compliance – PCI DSS for payments, HIPAA for health, KYC and AML for finance each add security work that is invisible on screen but real in the budget. And AI features – on-device or API-driven intelligence is increasingly common and adds model, data and evaluation work on top of the app itself.
iOS, Android, or both
Shipping to one platform is cheaper than two, but the gap is smaller than it looks if you go cross-platform, where most of the codebase is shared. With native, each platform is close to a full build, so “both” roughly doubles the front-end cost. The practical answer: most consumer products need both stores, so cross-platform is usually the economical route to that; a single-platform native build only makes sense when your audience is clearly on one platform or you need deep platform-specific capability. We build for iOS and Android natively and as cross-platform apps, and the choice is a cost decision as much as a technical one.
Timeline
A simple MVP ships in 2 to 4 months, a mid-complexity app in 4 to 7, and a complex or regulated app in 8 to 14 months or more, where security reviews, app-store approval and integration testing – not feature work – often set the schedule. App-store review itself adds days to weeks, and a regulated app adds compliance audits on top. Rushing the timeline rarely saves money; it usually moves cost into rework and post-launch fixes.
Ongoing cost after launch
The build is the start, not the end. Budget 15 to 25 percent of the build cost per year for maintenance: OS updates (iOS and Android ship breaking changes annually), security patches, third-party SDK upgrades, bug fixes and small features. Add app-store fees, backend and infrastructure hosting that scales with users, analytics and monitoring tools, and the cost of new features as the product grows. An app left unmaintained breaks within a year or two as the platforms move under it – ongoing investment is part of the total cost of ownership, which we cover in our custom software TCO report.
Common mistakes
The expensive errors repeat. Building native two-codebase apps when one cross-platform codebase would have served, and paying twice to build and maintain. Underscoping the backend, so the “simple app” balloons once real data and integrations land. Skipping design investment and shipping something that looks cheap, then rebuilding it. Treating compliance as a late add-on in a regulated app, when it should shape the architecture from sprint one. And ignoring maintenance in the budget, so the app rots after launch. Most overruns come from scoping decisions made before any code is written.
How to estimate your app
Start from three questions: how complex is the app really, do you need native or will cross-platform do, and how much backend and compliance sits behind it? Those three set the band more than the screen count. For most products, a cross-platform MVP that proves the idea with real users beats a gold-plated v1, and you scale the spend once the market answers. If you are building in a regulated space – a banking app, a health app, a payments product – budget for the security and compliance work up front, because that is what separates a $90,000 app from a $400,000 one. If you are scoping a build, our mobile app development team can size the complexity, platform and cost with you, including regulated FinTech apps where compliance is part of the engineering from day one.

A simple cross-platform app with a basic backend costs roughly $30,000 to $80,000 over 2 to 4 months. A mid-complexity app with custom design, accounts, payments and integrations runs $80,000 to $200,000 over 4 to 7 months.
A complex, multi-platform, AI-heavy or regulated app reaches $200,000 to $600,000 and up over 8 to 14 months. Complexity, not screen count, sets the band.
-
Cross-platform is usually cheaper. One codebase built with Flutter or React Native ships to both iOS and Android and is typically 30 to 40 percent less to build and maintain than two native apps.
Native earns its premium only for graphics-heavy, hardware-heavy or latency-critical apps. For most products in 2026, cross-platform is the economical default.
-
One platform is cheaper, but the gap is small if you go cross-platform, where most of the codebase is shared. With native, each platform is close to a full build, so shipping both roughly doubles the front-end cost.
Most consumer apps need both stores, which is why cross-platform is usually the economical route to reaching them.
-
A simple MVP ships in 2 to 4 months, a mid-complexity app in 4 to 7, and a complex or regulated app in 8 to 14 months or more. For regulated apps, security reviews, app-store approval and integration testing often set the schedule rather than feature work. App-store review alone adds days to weeks.
-
Budget 15 to 25 percent of the build cost per year for maintenance - OS updates, security patches, SDK upgrades, bug fixes and small features - plus app-store fees, backend and infrastructure hosting that scales with users, and monitoring tools. An app left unmaintained breaks within a year or two as iOS and Android move under it.
-
The biggest levers are app complexity, native versus cross-platform, the number of platforms, backend depth, the number of third-party integrations, design quality and compliance. Regulated domains add the most hidden cost: PCI DSS, HIPAA or KYC and AML work is invisible on screen but real in the budget, and it is what separates a $90,000 app from a $400,000 one.
-
A focused MVP - cross-platform, a handful of screens, standard UI, a basic backend with login and a couple of integrations - costs roughly $30,000 to $80,000 over 2 to 4 months. It is the cheapest way to validate an idea with real users before committing to a larger build.
-
Yes. On-device or API-driven AI adds model selection, data work and evaluation on top of the app itself, and ongoing inference costs after launch.
A simple AI feature is modest, but a data-heavy or custom-model capability can move an app into the complex band. Scope the AI separately from the app when you estimate.
Mobile app development glossary 8
- Native app
- An app built for one platform in its own language - Swift for iOS, Kotlin for Android - giving full performance and platform access at the cost of maintaining a separate codebase per platform.
- Cross-platform framework
- A toolkit such as Flutter or React Native that builds one codebase into both iOS and Android apps, typically 30 to 40 percent cheaper to build and maintain than two native apps.
- MVP (minimum viable product)
- The smallest version of an app that delivers core value and can be tested with real users. Building an MVP first keeps early spend low and lets the market guide further investment.
- Backend / API
- The server-side logic, data and services the app talks to over an API. For most apps the backend and integrations are a larger share of cost than the screens themselves.
- Third-party SDK
- A pre-built software development kit dropped in to add a capability - payments, maps, authentication, analytics, push. Each one adds integration and testing time.
- App Store review
- Apple and Google review every submission against their guidelines before it goes live. Approval adds days to weeks to the timeline and can require changes.
- MBaaS (mobile backend as a service)
- A hosted backend (auth, database, push, storage) such as Firebase that speeds up an MVP, trading some control and long-term flexibility for lower upfront build cost.
- App maintenance
- The ongoing work to keep an app running after launch - OS updates, security patches, SDK upgrades and fixes - usually 15 to 25 percent of the build cost per year.
