How much does a custom mobile app cost? A 2026 breakdown

Most custom mobile apps cost between $9,000 and $30,000, with a simple MVP starting around $5,000 and a complex native app with its own backend running $80,000 or more. Where you land is decided by three things: how many platforms you ship, how deep the features go, and whether the app needs a backend.

"A mobile app" describes everything from a single-screen utility to a multi-platform product with accounts, payments, real-time data, and an admin panel. The price follows the work, so the useful question isn't "what does an app cost?" but "what does my app actually need to do?"

Here's how I break it down before quoting.

A direct answer, by tier

• MVP / single-purpose app — roughly $5,000 to $15,000. Cross-platform, a handful of screens, basic features, a simple backend (Firebase or similar). Built to prove the idea with real users.
• Production app — roughly $9,000 to $30,000. Cross-platform with standard features (accounts, content, notifications), a real backend, and the polish to ship to the stores with confidence.
• Complex / native + custom backend — roughly $30,000 to $80,000+. Native iOS and Android, advanced features (chat, payments, real-time, offline sync), and a custom API. The class of app where the experience and reliability are the product.

These are ballparks, not quotes. For a number tuned to your platform, feature, and backend choices, the project cost calculator runs the same questions I'd ask on a call.

What actually moves the price

Three decisions account for most of the variance:

• Platforms. One cross-platform codebase (Flutter or React Native) serving iOS and Android is the cost-effective default. Two native codebases (Swift + Kotlin) roughly multiply the build and maintenance effort — worth it only when you need platform-specific performance or deep OS integration.
• Feature depth. A content app is cheap. The moment you add accounts, payments, chat, real-time updates, or offline sync, you're adding backend work, edge cases, and testing — and that's where the budget goes.
• Backend. No backend (fully on-device) is cheapest. A managed backend (Firebase / Supabase) covers most apps affordably. A custom API — needed for complex business logic, integrations, or scale — is its own line item.

Design and the number of integrations (payment, maps, analytics, third-party APIs) move the number too, but platform × features × backend is the spine of every estimate.

Cross-platform vs native: the biggest single lever

For most products, cross-platform wins: one codebase, one team, faster iteration, and a single place to fix bugs. Modern Flutter and React Native are more than good enough for the vast majority of apps, and the cost savings are real.

Native earns its higher cost in specific cases: heavy graphics or AR, tight hardware/OS integration, or a UX that must feel perfectly platform-idiomatic. If those aren't hard requirements, paying for two native codebases is usually budget you could spend on features instead.

Picking wrong is expensive in both directions — native for what should've been cross-platform burns budget; cross-platform for something that genuinely needed native ships something that underperforms.

The costs that aren't in the build quote

The development quote is the biggest number, not the only one:

• App store fees. Apple's Developer Program is an annual fee; Google Play is a one-time registration. Small, but real, and required to publish.
• Backend hosting. A managed backend or custom API has an ongoing monthly cost that scales with usage.
• Maintenance and OS updates. iOS and Android ship breaking changes yearly. An app that isn't maintained quietly rots — budget for ongoing updates, not just the build.
• Post-launch iteration. The first version teaches you what users actually do. A small budget for adjustments protects the value of the whole build.
• Third-party services. Payments, push, maps, and analytics often carry their own usage-based costs.

None of these are hidden fees — they're the difference between "the app is built" and "the app is running and healthy in the stores."

Why a cheaper quote can cost more

Two studios can quote the same app and mean very different things. The cheaper one may be planning a thin prototype that looks right in a screenshot; the other a production app that handles errors gracefully, survives a flaky network, passes store review, and can be maintained by your team a year later.

For a real product, that gap matters. An app that crashes on edge cases, can't be updated without the original developer, or fails App Store review isn't cheaper — it just moves the cost downstream.

How to get a real number for your project

A blog range only gets you so far. To estimate yours:

1. Decide the platforms — cross-platform, single native, or both native.
2. List the features that genuinely matter for version one.
3. Decide the backend — none, managed, or custom.
4. Run those answers through the cost calculator for an instant ballpark.

If you're weighing other build types, the VR training and AR app cost guides break those down the same way. And if you'd rather talk it through, start a conversation — tell me the platforms and the core features, and I'll give you a realistic range and a scope to match it.
