Anyone who contacts us with a project has the same question in mind before even discussing features: what’s the real custom mobile app development cost. Not a vague range pulled from a forum, a number you can defend in front of an investor or a steering committee. The cost of developing a custom mobile app depends on specific choices, native or cross-platform, MVP or full product, local team or offshore, and each of these choices has a measurable impact on the final bill. Let’s break it down line by line.
A custom mobile app costs between €15,000 and €40,000 excl. VAT for an MVP published on iOS and Android, and between €40,000 and €120,000 excl. VAT for a more ambitious enterprise project. Annual maintenance then adds 10 to 25% of the initial budget, every year (2026 data).
- The mobile app development cost varies widely depending on complexity, the number of platforms, and the features actually coded.
- The technology choice (native iOS, native Android, cross-platform) directly changes the budget and timeline.
- UX/UI design, third-party integrations, and maintenance weigh just as heavily as pure development in the total budget.
- Precisely scoping the need before coding is what prevents the most budget overruns when figuring out how much does it cost to build an app.
- Maintenance represents 10 to 25% of the initial price each year: a recurring cost too often overlooked in estimates.
What does a native app cost and what factors affect it?
A native iOS app alone costs between €15,000 and €40,000 excl. VAT for an MVP and between €40,000 and €120,000 excl. VAT for an ambitious project. Adding Android nearly doubles the code, but the total budget only increases by about half to two-thirds, thanks to design and back-end reuse (2026 data).
Native remains the choice that gives you the most headroom on performance and access to phone functions, camera, sensors, fine-grained push notifications. It’s also the most expensive upfront, because you need to write two separate codebases if you want to cover iOS and Android: Swift on one side, Kotlin on the other. We rarely recommend dual native for a startup launching its MVP, the budget quickly gets burned across two parallel teams instead of one moving forward.
Factors affecting mobile app development cost
Two apps with the same number of screens can have a price that varies by a factor of three depending on what happens behind each button. An appointment booking app that simply displays a calendar has nothing in common, code-wise, with an app that handles split payments and a real-time queue.
- Number of screens and user journeys to design and code.
- Feature complexity: integrated payments, geolocation, offline sync, video calling.
- Number and complexity of third-party integrations (payment APIs, CRM, ERP, delivery services).
- Whether or not an admin back office is needed to manage content.
- Data volume and security requirements (healthcare, finance, sensitive personal data).
Native, hybrid, or PWA: the trade-off that changes everything
The real strategic choice, before discussing budget, is the type of app. A native app is developed specifically for iOS or Android, using each platform’s own language and tools, it’s the most performant, and the most expensive. A hybrid app uses a single codebase (React Native, Flutter) compiled for both systems: this is the most common compromise today for controlling the average cost to create a mobile app without sacrificing too much quality. A progressive web app (PWA) is downloaded from a browser, without the mandatory app store route, ideal for testing a concept at a lower cost, but with limitations on native phone functions.
A React Native MVP falls within the same range as a single-platform native MVP, between €15,000 and €40,000 excl. VAT, and an enterprise React Native project rises to between €40,000 and €120,000 excl. VAT (2026 data). The difference isn’t in the starting price but in the coverage: with React Native, the same budget covers iOS AND Android from day one, because a single codebase runs on both.
The classic trap is choosing native by reflex for “premium quality” when the project has no feature that truly requires it. We’ve seen project owners double their budget for a performance gain that 95% of their users will never notice.
How to control the budget for a custom mobile app?
Controlling your mobile app development budget comes down to precise scoping before the first screen is coded: defining the MVP scope, prioritizing features, choosing the right stack, and negotiating development in batches rather than a single fixed block.
The method that works best, project after project, is to break things into phases rather than trying to deliver everything at once. An MVP covering the core use case, tested with real users, often costs ten times less than a full product launched blindly, and avoids paying for features no one will ever use.
Cost breakdown for mobile app development: the items too often forgotten
Pure development is only part of the bill. A realistic cost breakdown for mobile app development also includes UX/UI design (often 15 to 25% of the total budget), testing and deployment on both stores, project management, and a margin for technical surprises, a third-party API integration that changes without notice, a compatibility bug on a specific Android model. Project owners who negotiate their quote solely on coding time often end up with a 20 to 30% overrun along the way, because design, testing, and deployment were never priced separately.
Mobile app development pricing guide: the calculation method, not a magic number
A serious quote details the items separately, number of screens, complexity, integrations, design, project management, rather than an opaque flat fee. This is what allows you to compare two commercial proposals on a common basis, and spot the one that omitted an item (often maintenance or testing) to appear cheaper on paper.
- List the features essential for launch, separate from those that “would be nice.”
- Get a strict MVP priced before discussing a full product.
- Request a detailed quote by item: design, development, testing, deployment, maintenance.
- Compare the proposed stacks (native vs. cross-platform) on the same functional scope.
- Negotiate milestone-based payments rather than a single upfront deposit on the whole project.
- Include the following year’s maintenance line right in the initial quote.
What tools for mobile app development and how to design a smartphone app without coding?
Three paths exist to create a mobile app: a specialized agency that develops custom solutions, learning to code in-house, and no-code tools or app builders that let you design an app without writing a single line. Each path has a different cost and complexity ceiling.
Free software to create a mobile app: how far does it really go?
There are solutions to create a mobile app for free or at very low cost, app builders that offer pre-designed templates, a bit like a brochure site built on a generic CMS. They work for a simple showcase, a static product catalog, a prototype to show investors. The trouble starts as soon as you want a specific feature: split payments, complex synchronization with an ERP, a recommendation algorithm. An app builder quickly hits its technical ceiling, and migrating to custom development later often costs more than if you had started custom from day one, because everything has to be rebuilt, not just continued.
Custom app development: when to switch to bespoke
The tipping point is quite clear in practice: as soon as an app needs its own business logic (dynamic pricing, real-time inventory management, matching between two types of users), building a mobile app on a generic tool becomes a hindrance rather than a help. We’ve seen project owners waste months working around a builder’s limitations instead of investing that time in custom development that would have handled the load from the start.
The following table compares costs based on app complexity, a direct reference point for situating a mobile app development cost before even requesting a detailed quote.
In concrete terms, a project owner aiming for a fast launch should price their need on the MVP line and accept that a higher budget doesn’t necessarily speed up time-to-market, it’s the functional scope that dictates the timeline, not the check amount.
An enterprise project costs up to 3 times more than a mobile MVP
For a mobile app MVP published on iOS and Android, the budget falls between €15,000 and €40,000 excl. VAT, with a two-to-three-month timeline until store publication. An ambitious enterprise project reaches €40,000 to €120,000 excl. VAT.
A project owner starting out should aim for the MVP bound and not the full project: the budget nearly triples between the two, for a codebase that evolves progressively. It’s better to validate your market before investing in the ambitious version.
| Element | Value (€) |
|---|---|
| MVP | €27,500 |
| Enterprise project | €80,000 |
| Median business tool | €20,000 |
| Median all projects | €30,000 |
How much does app maintenance cost and what’s the price to put an app on the Play Store or App Store?
App maintenance costs between 10 and 25% of the initial development price, every year, that’s €5,000 to €12,500 per year for a €50,000 app. Publishing on the App Store and Google Play Store, on the other hand, is nearly free: the real cost comes from the preparation time, not the account fees.
App store application: what the App Store and Play Store really require
Publishing an app on the App Store requires a paid annual Apple developer account, and on the Google Play Store a Google developer account with a one-time registration fee. These amounts remain modest compared to the development budget, the real cost is the preparation: screenshots, optimized description, compliance testing against each store’s rules, and sometimes back-and-forth validation with Apple, which is stricter than Google on manual review. The price to put an app on the Play Store or App Store, in direct fees, weighs little against the 2 to 3 months of development needed for a complete MVP before even thinking about publication.
Mobile app development cost: why maintenance often hurts more than development
An app is never “finished” once published. Operating systems evolve, Apple and Google impose regular compliance updates, and each new version of iOS or Android can break a feature that worked perfectly the day before. That’s why app maintenance represents 10 to 25% of the initial budget per year: bug fixes, security updates, adaptation to new OS versions, performance monitoring. A project owner who budgets only for initial development and forgets this line finds themselves, a year after launch, with an app that crashes on the latest smartphones, and an emergency budget to find in a rush, under far worse conditions than planned maintenance.
Monetization and return on investment: the blind spot in the initial budget
The choice of app monetization model (one-time purchase, subscription, advertising, freemium) also impacts the cost of developing a custom mobile app. A subscription with recurring payment requires a more advanced integration (handling renewals, cancellations, billing) than a simple one-off purchase. Thinking about monetization from the scoping phase, not after launch, avoids a costly overhaul of the payment system once the app is already in production.
Depending on your situation
A startup launching its first MVP before a funding round
The number one criterion here is speed to market to validate the concept with investors. The right option is a cross-platform MVP (React Native or Flutter), between €15,000 and €40,000 excl. VAT, delivered in two to three months. No dual native at this stage: the budget should serve to test the market, not to polish performance no one has asked for yet.
An SME with 20 employees digitalizing an internal business process
Here, the priority shifts: no public store, no consumer-grade design to polish, but reliable business logic and clean integration with the existing ERP or CRM. The observed median for this type of tool sits around €20,000. Custom development almost always wins over an app builder, because the specific business logic quickly exceeds what a generic tool can do.
An established company wanting an ambitious consumer app
The expected budget here climbs between €40,000 and €120,000 excl. VAT, because the level of demand on design, performance, and third-party integrations (payment, notifications, advanced analytics) is much higher. The native choice regains its full meaning here: the user experience must rival the best apps on the market, not just function.
The mistakes that cost the most
- Starting development without detailed functional specifications, and discovering hidden costs along the way.
- Choosing dual-platform native by default, without assessing whether cross-platform would suffice. Doubling development with a second native Android increases the budget by about half to two-thirds compared to a single native platform.
- Forgetting the maintenance line in the annual forecast budget. Agencies report between 10 and 25% of the initial price per year, or €5,000 to €12,500 per year for a €50,000 tool.
- Starting on an app builder for complex business logic, then having to rebuild everything custom a year later.
- Neglecting App Store compliance testing, which delays publication by several weeks.

FAQ
What is a web app and what’s the difference from a native mobile app?
A web app (or PWA) loads in a browser without installation from a store, while a native mobile app is installed from the App Store or Google Play Store and directly accesses phone functions (camera, GPS, notifications). Native offers more performance; the web app costs less and updates instantly.
What stack to choose for a custom mobile app in 2026?
React Native and Flutter dominate for cross-platform: a single codebase for iOS and Android, a controlled budget. Native (Swift, Kotlin) remains relevant for apps with very high demands on performance or deep hardware access. The choice depends on the project’s technical requirements, not on a trend.
Is it better to use a specialized agency or freelancers to create a mobile app?
An agency provides a single point of contact, a complete team (design, development, testing), and structured follow-through from scoping to launch. A freelancer sometimes costs less per hour, but carries all roles alone, with higher risk on deadlines and continuity in case of unavailability.
How to evaluate the return on investment of a custom mobile app?
Return on investment is measured by comparing the total cost (development plus maintenance over several years) to the gain generated: new customers acquired, internal time saved, additional sales via the app. An MVP tested quickly allows validating this ROI before investing in the full version.
The custom mobile app development cost never boils down to a single number pulled from a price list: it’s the result of precise scoping, a deliberate technology choice, and maintenance anticipated from the very first quote. At Skyward Agency, scoping happens before any financial commitment, with custom development driven by an offshore team based in Mauritius, at a controlled rate without sacrificing quality. The best reflex now: request a scoping of your project to get a detailed quote, line by line, rather than a generic range.
