App development costs range from $10,000 to $500,000 or more, depending on what you're building and who builds it

The price depends on four things: complexity, platform choice, who you hire, and what features you need. A simple iOS app from a freelancer costs far less than a native app for both iOS and Android built by an agency. A basic app with a few screens and straightforward functions might run $15,000 to $40,000. A more complex app with user accounts, payment processing, and real-time data can reach $75,000 to $200,000. Enterprise apps with custom backends and integrations often exceed $300,000.

The biggest cost driver is not the idea—it's the scope. Adding features, supporting multiple platforms, and building custom infrastructure all add time and therefore money. A freelancer or small team charges less per hour than an agency, but may take longer or have less availability. An agency costs more but typically delivers faster and handles more complex work.

Key Takeaways

  • A simple app costs $15,000 to $40,000; a moderately complex app costs $75,000 to $200,000; enterprise apps often exceed $300,000.
  • Building for one platform (iOS or Android) costs significantly less than building for both, and cross-platform tools like React Native or Flutter can reduce that gap.
  • Freelancers charge $25 to $150 per hour; small agencies charge $50 to $200 per hour; large agencies charge $150 to $300 per hour.
  • The cost of building the app is separate from ongoing costs like hosting, maintenance, app store fees, and updates.
  • Scope creep—adding features after development starts—is the most common reason projects exceed their budget.

How platform choice affects the price

Building for one platform costs less than building for two. An iOS-only app typically costs 20 to 30 percent less than an app that runs on both iOS and Android, because the developer writes the code once instead of twice. If you start with iOS and add Android later, you're paying for two separate builds.

Cross-platform frameworks like React Native and Flutter let one developer write code that runs on both platforms, which can cut costs by 30 to 50 percent compared to native development. The trade-off is that cross-platform apps sometimes perform slightly slower or have fewer access to device features. For most business apps, the cost savings outweigh the performance difference.

Web apps (apps that run in a browser) cost less than mobile apps because they don't need to be built separately for iOS and Android. A web app might cost $10,000 to $50,000. The downside is that users access it through a browser rather than downloading it from the App Store or Google Play, which changes how people discover it.

What you pay different types of developers

Freelancers typically charge $25 to $150 per hour, depending on experience and location. A freelancer in Eastern Europe or South Asia costs less than one in North America or Western Europe. Hiring a freelancer works well for small, well-defined projects—a simple app might take 400 to 800 hours, so you're looking at $10,000 to $120,000. Freelancers are slower to scale if you need to add features later, and you carry more risk if they disappear or the work quality drops.

Small agencies (5 to 20 people) charge $50 to $200 per hour. They're faster than freelancers, have backup staff if someone gets sick, and often have designers and project managers included. A small agency might complete a moderately complex app in 3 to 6 months. The same project with a freelancer might take 6 to 12 months.

Large agencies charge $150 to $300 per hour and handle enterprise-scale projects. They have dedicated teams, established processes, and experience with complex integrations. You pay for speed, reliability, and the ability to scale quickly. A large agency is overkill for a simple app but necessary for apps that need to handle millions of users or integrate with multiple backend systems.

Breaking down what's included in the cost

App development cost covers design, coding, testing, and deployment to the app store. Design includes wireframes (sketches of how the app looks), mockups (detailed visual designs), and user experience planning. Coding is the actual programming. Testing means checking that features work and don't crash. Deployment means getting the app into the App Store or Google Play.

What's not included: hosting (the servers that run your app's backend), app store fees (Apple charges $99 per year; Google charges $25 once), ongoing maintenance, bug fixes after launch, and new features added later. Many developers charge a separate maintenance retainer—typically $1,000 to $5,000 per month—to handle updates and small fixes.

If your app needs a backend (a server that stores data, handles user accounts, or processes payments), that's a separate cost. A simple backend might add $10,000 to $30,000. A complex backend with real-time features, analytics, and integrations can add $50,000 to $150,000 or more.

How to estimate costs for your specific app

Start by listing features: user login, payment processing, push notifications, maps, real-time chat, video streaming, or offline mode. Each feature adds time and cost. A simple app with 3 to 5 screens and no backend might take 200 to 400 hours. A moderately complex app with 10 to 15 screens, user accounts, and a backend might take 600 to 1,200 hours. A complex app with 20+ screens, real-time features, and custom integrations might take 1,500 to 3,000 hours or more.

Multiply hours by the hourly rate of whoever you hire. If a freelancer charges $75 per hour and your app needs 800 hours, the cost is roughly $60,000. If a small agency charges $100 per hour, the same app costs $80,000. These are estimates—actual costs vary based on the developer's speed, the complexity of your specific features, and how much the scope changes during development.

Get quotes from at least three developers before deciding. Provide the same detailed description to each so you can compare fairly. The cheapest quote is not always the best; a developer who quotes half the price of others may be underestimating the work or cutting corners.

Why costs increase during development

Scope creep is the most common reason projects go over budget. You start with a list of features, but during development you decide to add more: a new screen, a different payment method, integration with a third-party service. Each addition takes time, which costs money. To avoid this, lock down the feature list before development starts and treat additions as separate projects with separate budgets.

Technical complexity often exceeds initial estimates. A developer might think a feature will take 20 hours but discover it actually takes 40 because of unexpected technical challenges. This is why experienced developers build in buffer time and why their estimates are higher than inexperienced ones.

Changes to the design during development also add cost. If you decide halfway through that the app should look completely different, the developer has to redo work they already completed. Approve the design thoroughly before coding starts.

Alternatives if the cost is too high

Build a minimum viable product (MVP) first. An MVP includes only the core features needed to solve the problem—no fancy design, no extra features, no backend complexity. An MVP might cost $15,000 to $40,000 and launch in 2 to 3 months. Once you have users and feedback, you can add features in later versions. This approach spreads costs over time and reduces the risk of building something nobody wants.

Use no-code or low-code platforms like FlutterFlow, Bubble, or Adalo. These let you build apps by dragging and dropping components instead of writing code. They cost $50 to $500 per month and can reduce development time by 50 to 70 percent. The trade-off is that you're limited to what the platform allows—you can't build highly custom or complex apps.

Hire a developer from a lower-cost region. Developers in India, the Philippines, or Eastern Europe charge $20 to $60 per hour compared to $75 to $200 in North America. The quality varies widely, so check portfolios and references carefully. Time zone differences can also slow communication.

Frequently Asked Questions

How long does it take to build an app?

A simple app takes 2 to 4 months. A moderately complex app takes 4 to 8 months. A complex app can take 12 months or longer. Speed depends on the developer's experience, how clear your requirements are, and how much the scope changes. Larger teams finish faster than smaller ones.

Can I build an app for less than $10,000?

Yes, but only for very simple apps. A basic app with 2 to 3 screens and no backend might cost $5,000 to $10,000 from a freelancer. No-code platforms can cost even less if you build it yourself. Anything more complex will cost more.

What's the difference between native and cross-platform development?

Native apps are built separately for iOS and Android using each platform's native tools. They perform better and have full access to device features, but cost more because you're paying for two builds. Cross-platform apps run on both platforms from a single codebase, cost less, but may perform slightly slower.

Do I need to pay for hosting after the app launches?

Only if your app has a backend that stores data or processes information. A simple app that just displays information doesn't need hosting. If you do need hosting, costs typically range from $50 to $500 per month depending on how many users you have and how much data you store.

What happens if I want to add features after launch?

New features are billed separately, usually at the same hourly rate as the original development. A simple feature might cost $2,000 to $5,000. A complex feature might cost $10,000 to $30,000 or more. Budget for ongoing development if you plan to keep improving the app.
