How much does it cost to build a mobile app in 2026?

"How much does an app cost?" is like asking how much a house costs: it depends on the size, the finishes and where you build it. But we can give you the factors that move the price and ballpark ranges so you can plan sensibly.

The factors that determine the price

The cost of an app is driven, above all, by five variables. Understanding them lets you prioritise and adjust the budget without sacrificing what matters.

• Functional scope: how many screens and what logic (a catalogue is not a marketplace with payments).
• Platforms: iOS only, Android only, or both; native or cross-platform.
• Backend: whether it needs a server, a database, user accounts and an admin panel.
• Integrations: payments, maps, AI, external systems (ERP, CRM).
• Design: a custom UX/UI versus a template.

Ballpark ranges

Broadly speaking, a simple MVP (few screens, a basic backend) starts from a modest investment; an app with user accounts, payments and a management panel rises noticeably; and a complex platform with real time, AI or large scale is a major project. Rather than a fixed figure, what is useful is defining the scope well: the same budget performs very differently depending on where you put it.

Native vs. cross-platform

Developing natively (Swift, Kotlin) separately for iOS and Android maximises performance but doubles the effort. Cross-platform technologies like React Native allow a single codebase for both stores, reducing cost and time with excellent performance for most apps. Unless there are very specific needs, cross-platform tends to be the most cost-effective option.

How to save without losing quality

The most effective way to control cost is not to cut quality, but to phase the project: start with an MVP that validates the idea with real users and grow with data. That way you invest where it really matters and avoid building features nobody uses.

• Start with an MVP focused on the core value proposition.
• Reuse a cross-platform base to cover iOS and Android at once.
• Prioritise with real usage data before adding features.

Hidden costs that are often forgotten

The development budget is just the tip of the iceberg. There are recurring items that almost nobody includes in their initial calculations and that, added together, can represent a very significant share of the spend over the life of the app. It is worth being clear about them before you start so you avoid surprises.

• Store commissions: the Apple App Store and Google Play take up to 30% (15% in many cases for small businesses or long-term subscriptions) of every digital sale, plus the developer account fees ($99/year for Apple, a one-off $25 for Google).
• Maintenance and updates: iOS and Android release new versions every year; your app needs to adapt to those changes, to new screen sizes and to privacy requirements so it does not stop working or get pulled from the store.
• Backend and hosting: servers, database, file storage, push notifications and third-party services generate a monthly cost that grows with the number of users.
• Support and monitoring: handling incidents, fixing reported bugs and watching performance and security requires time and tools on an ongoing basis.

None of these costs is optional if you want a living, reliable app. The advisable approach is to estimate them from the start and set aside an annual maintenance budget, which as a reference usually sits between 15% and 25% of the initial development cost.

Total cost of ownership (TCO), not just development

The most expensive mistake when planning an app is focusing only on the initial price. The metric that really matters is the total cost of ownership (TCO): what it will cost you to build, maintain and evolve the app over two or three years, which is the realistic horizon for a digital product that aims to grow.

Thinking in terms of TCO changes the decisions. A cheaper option at the start can turn out far more expensive if it generates technical debt, relies on technology that will soon be obsolete or ties you to a provider who overcharges for every change. That is why from day one we value factors like code quality, a cross-platform base that reduces maintenance, real ownership of the code and an architecture ready to scale. Looking at the whole picture, and not just the launch invoice, is what separates a profitable app from a cost that keeps growing.
