Mobile app development costs vary enormously by scope, but published industry estimates commonly put simple apps in the $10,000–$50,000 range, moderate apps around $50,000–$150,000, and complex, feature-heavy platforms well above that — often $150,000 to $400,000+. The honest answer to "how much does an app cost" is always "it depends on what you're actually building," but those published ranges at least give you a realistic starting point. What actually drives the cost within those ranges is complexity: how many screens, how much custom backend logic, how many third-party integrations, and whether you need native iOS and Android apps or a single cross-platform build.

Cost by App Complexity

Industry pricing guides generally group apps into three rough tiers:

  • Simple apps (a handful of screens, no complex backend, minimal custom features) — commonly cited around $10,000 to $50,000.
  • Moderate apps (user accounts, a real backend, some third-party integrations like payments or maps) — commonly cited around $50,000 to $150,000.
  • Complex apps (real-time features, heavy custom logic, multiple integrations, enterprise requirements) — commonly cited at $150,000 and up, sometimes reaching $400,000 or more for the most demanding builds.

These are broad industry ranges pulled from published pricing guides, not a quote for your specific project — the only way to get an accurate number is to scope your actual feature list against your actual requirements.

Native vs. Cross-Platform: The Real Cost Difference

Building separately for iOS (Swift) and Android (Kotlin) usually costs more than a single cross-platform codebase (like React Native), since you're effectively building two apps instead of one. Cross-platform is often the more cost-effective choice unless you need something that specifically requires deep native performance or platform-specific features — most business apps don't.

What Actually Drives Cost Beyond "Simple vs. Complex"

  • Backend complexity: an app that just displays content costs far less than one managing real-time data, user accounts, and business logic.
  • Third-party integrations: payment processing, maps, push notifications, and CRM connections each add scope.
  • Design complexity: a highly custom, animation-heavy interface costs more than a clean, functional one.
  • Ongoing maintenance: app stores update their requirements regularly, and a published app needs upkeep — budget for this beyond the initial build.

How to Actually Reduce Costs Without Cutting Corners

The most reliable way to control cost is starting with an MVP — the smallest version of the app that actually tests your core idea with real users — rather than building every feature you can imagine before launch. Many features that seem essential upfront turn out to be unnecessary once real usage data comes in, and it's far cheaper to learn that before building them than after. See our MVP and product development services for how this works in practice.

Choosing a Development Partner

Get a detailed, itemized quote rather than a single number — you want to see what's actually included (design, development, testing, app store submission, post-launch support) so you can compare quotes on equal footing. A vague, all-in number is harder to evaluate than a clear breakdown. Our mobile app development services page has more on how we scope and price projects.

Frequently Asked Questions

Can I get an app built for under $10,000?

It's possible for a very simple app with minimal custom functionality, but most business apps with real features (accounts, backend logic, integrations) start above that range. Be cautious of quotes far below published market ranges — they often mean cut corners on testing, security, or post-launch support.

Is it cheaper to build one app for both iOS and Android?

Generally yes — a single cross-platform codebase costs less than building and maintaining two separate native apps, unless your specific use case genuinely requires native-only capabilities.

What's the biggest hidden cost people miss?

Ongoing maintenance. Apps need updates as operating systems change, and neglecting this leads to a stale app that eventually stops working properly — budget for it as an ongoing cost, not a one-time expense.

Should I build an MVP first or the full app?

For most businesses, starting with an MVP is the lower-risk, lower-cost path — you validate the idea with real users before investing in every feature you originally imagined.

How do I compare quotes from different agencies fairly?

Ask for an itemized breakdown, not just a total number, and make sure each quote covers the same scope — design, development, testing, and post-launch support — so you're comparing like for like.
