How Much Does a Mobile App Cost in Spain in 2026?

Asking for a mobile app quote in Spain still feels like a lottery: the same brief can come back with offers of 3,000 EUR and 60,000 EUR. The difference is rarely quality; it is the scope each supplier assumed. This guide gives you real 2026 price ranges by app type, the factors that actually move the price, and the mistakes that inflate a project the most.

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

In 2026, a hybrid MVP with the essential features costs between 5,000 and 12,000 EUR. A native app of medium complexity, with its own backend, login and push notifications, sits between 12,000 and 30,000 EUR. Beyond that, projects with integrated payments, offline mode or specific hardware go past 30,000 EUR. On top of development, plan for annual maintenance of around 15-20% of the initial cost. These are ranges for Spanish agencies with senior in-house teams, not freelance rates or offshore factory prices.

The lower range does not mean a worse app, it means a smaller scope. A 5,000-12,000 EUR MVP typically includes 5 to 8 screens, a simple backend and publication on the App Store and Google Play. A 12,000-30,000 EUR app adds user roles, integrations with existing systems and more refined design work. If a very cheap quote promises the second for the price of the first, something is missing: testing, backend or post-launch support.

What factors move the price of a mobile app?

The first factor is the number of screens and flows: each screen with its own logic adds between 300 and 800 EUR in development and testing. The second is the backend: an app that only displays data is far cheaper than one that manages users, permissions and synchronisation. The third is integrations: connecting the app to an existing ERP or CRM typically costs between 1,500 and 4,000 EUR, depending on the quality of the other system's API.

Some factors are consistently underestimated at quoting time. In-app payments add a gateway, store commissions and legal requirements. Offline mode forces you to synchronise data and resolve conflicts, and can double the cost of a feature. And GDPR is not optional: if the app handles personal data, consent, encryption and retention policies must be budgeted from day one, not patched in later.

Native or cross-platform: which option keeps the budget down?

For most business apps, cross-platform development with Flutter or React Native cuts the cost by 30 to 40% compared with building two native apps, because a single codebase serves both iOS and Android. Pure native pays off when you need demanding graphics performance, deep hardware access or tight integration with the operating system. We compare both approaches in detail in our guide on native or cross-platform development.

The decision also affects maintenance. With two native apps you pay for every fix and every new feature twice, once per platform. With cross-platform, a 15,000 EUR app at 15-20% annual maintenance costs 2,250 to 3,000 EUR per year; the same app built twice natively can reach 4,000 to 6,000 EUR. Before choosing out of habit or fashion, calculate the 3-year cost, not just the initial budget.

How much does it cost to maintain a mobile app each year?

Budget between 15 and 20% of the development cost per year. A 20,000 EUR app needs 3,000 to 4,000 EUR annually to keep working well. That money is not optional: Apple and Google release new versions of iOS and Android every year, libraries become obsolete and the stores remove apps that stop being updated. An app abandoned for 18 months usually needs a catch-up project that costs more than the maintenance it skipped.

The most predictable formula for an SME is a technical retainer from 500 EUR per month, covering system updates, bug fixes and small improvements with a fixed point of contact. The alternative, one-off fixes from 300 EUR when something breaks, works for simple apps with light usage, but becomes more expensive as soon as there are recurring incidents or dependencies that break with each new iOS release.

Which mistakes inflate a mobile app quote?

The most expensive mistake is requesting quotes without a defined scope. If you send an email saying you want an app like some well-known product, every supplier will read it differently and you will receive figures from 3,000 to 60,000 EUR that are impossible to compare. Before asking for a price, list the screens, the user types and the integrations with your current systems. With that one-page document, offers become comparable and the final price stays close to the initial one.

The second mistake is hiring by the hour with no cap. A 40 EUR hourly rate looks cheap until the project consumes 800 hours, 32,000 EUR, with no end date. Demand a fixed price against a written scope. The third is not asking who owns the code: if the supplier keeps ownership or access to the store accounts, every future change goes through them at whatever price they decide.

How do you know the exact price before signing anything?

The serious way to fix a price is to analyse before quoting. At ASD Solutions we start with a paid audit: for 190 EUR we analyse your idea or your current app, with an initial diagnosis within 72 hours and a full report within 5 working days covering scope, a closed price range and a phased plan. If the project goes ahead, the 190 EUR is deducted from the budget.

From there, the same senior engineer who prices the project is the one who builds it, with no subcontracting and a fixed price agreed before work starts. The code and the store accounts are yours from day one, with no lock-in and no dependency on the supplier. You can see timelines and prices in detail on our mobile app development service page, and if the scope is unclear, the audit is the lowest-risk starting point.
