What does building an app cost in 2026: native vs cross-platform

Building two separate native apps, one for iOS and one for Android, means double the work and nearly double the cost in practice. That is why most of our clients in 2026 choose cross-platform or a PWA. Building an app with us starts around €18,000 and runs up to €70,000 for complex builds. Here is how that range works.

Native, cross-platform or PWA?

Before you look at price, you pick a technical foundation. There are three routes:

• Native (Swift for iOS, Kotlin for Android): maximum performance and access to all device features, but you build and maintain two codebases. The most expensive.
• Cross-platform (React Native): one codebase for both platforms, 30 to 40 percent cheaper, with performance that is more than enough for 95 percent of apps.
• PWA (Progressive Web App): a web app that behaves like an app, installable without an app store. The cheapest and fastest to launch.

Our CalorForm fitness app is deliberately a PWA: no app store approval, one codebase, and shareable directly via a link. For many ideas that is the smartest start, especially while you are still testing whether the market is ready. A PWA also sidesteps the app store commission, which can run up to 30 percent on payments. For a product with subscriptions or in-app purchases that adds up quickly.

The choice is not a matter of taste but of requirements. If your app needs heavy 3D graphics, continuous background location or deep integration with device hardware, native wins. For the rest, and that is the majority, cross-platform or a PWA delivers the same user experience at lower cost.

What sets the price?

The platform choice is one factor, but the real price is in what the app does:

• Number and complexity of features: a simple content app is a different thing from an app with real-time chat, geolocation and payments.
• Backend: an app without a server is cheap, but once you need accounts, data storage and APIs serious work is added. We build that backend on Laravel.
• Integrations: payment providers, mapping services, push notifications, external APIs.
• Design: a clean standard design is cheaper than a fully custom interface with animations.
• Offline functionality: syncing data over a changing connection is technically hard and therefore more expensive.

Price ranges in 2026

Based on what we build, the ranges look like this:

• Simple app or PWA (content, forms, basic backend): €18,000 to €30,000.
• Average app (accounts, payments, push, one or two integrations): €30,000 to €50,000.
• Complex app (real-time, offline sync, multiple integrations, AI components): €50,000 to €70,000 plus.

On top of the build cost, budget for ongoing costs: app store accounts (€99 per year for Apple, a one-time €25 for Google), backend hosting from €495 per month, and maintenance for OS updates that need attention every year again. That maintenance line is often forgotten, but it is real: every new iOS or Android version can break something, and without maintenance your app eventually stops appearing or crashes on new devices.

A common miscalculation is that the build price is the final figure. In practice an app is an ongoing product, not a one-off project. For the first year after launch, budget roughly 15 to 20 percent of the build cost for maintenance and ongoing development, and factor that into your business case before you start.

A handy test when estimating: count the number of screens, the number of external connections and whether payments or accounts are involved. An app with five screens, no payments and one connection sits at the bottom of the range. An app with thirty screens, subscriptions, push notifications and three integrations sits at the top or above. The sum of those components predicts the price better than the platform choice alone.

The mistake that costs the most money

The biggest mistake is building native for two platforms straight away while your idea is still unproven. You double your costs before you know whether people even want to use the app. Our approach: start with a PWA or cross-platform MVP, prove the core behavior, and only build native when performance or a specific device feature truly requires it.

• Start small, measure real usage, expand based on data.
• Choose native only when you have a concrete technical reason (heavy graphics, complex sensors).
• Keep the backend production-grade from the start, so you do not have to rebuild at growth.

The technology has matured so much in recent years that users barely notice the difference between a well-built cross-platform app and a native one in practice, while the difference in build and maintenance costs stays significant. That makes the trade-off simple for most companies: start pragmatic, prove the value, and only invest in native when a concrete requirement calls for it.

Conclusion

For most companies, cross-platform or a PWA is the sensible choice in 2026: lower costs, faster launch, one codebase. Reserve native for apps that genuinely need it. Want to know which route fits your idea? See our app development for a tailored estimate.
