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, along with ballpark ranges, so you can plan with a clear head.

The factors that determine the price

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

• Feature scope: how many screens and what logic (a catalog 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 (a few screens, a basic backend) starts from a modest investment; an app with user accounts, payments and a management panel rises notably; and a complex platform with real-time features, AI or large scale is a much bigger project. Rather than a fixed figure, what really helps is defining the scope well: the same budget delivers very different results depending on where you put it.

Native vs. cross-platform

Building natively (Swift, Kotlin) separately for iOS and Android maximizes performance but doubles the effort. Cross-platform technologies like React Native let you maintain a single codebase for both stores, cutting cost and time while delivering excellent performance for most apps. Unless you have very specific needs, cross-platform is usually the more cost-effective choice.

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 from there, guided by data. That way you invest where it truly matters and avoid building features no one uses.

• Start with an MVP focused on your core value proposition.
• Reuse a cross-platform codebase to cover iOS and Android at once.
• Prioritize based on real usage data before adding more features.
