App development costs range from a few thousand dollars to millions, depending on what the app does and who builds it

The price of creating an app depends on three things: complexity, the platform (iOS, Android, or both), and who does the work. A straightforward app with basic features built by a freelancer might cost $5,000 to $15,000. A moderately complex app from a small agency runs $25,000 to $100,000. A full-featured app for both iPhone and Android from an established firm can easily exceed $200,000. These are not fixed prices — they vary by region, the developer's experience level, and what features you actually need.

The biggest cost driver is scope: what the app actually does. An app that displays static information costs far less than one that processes payments, stores user data securely, or connects to multiple external services. The second driver is platform choice. Building for iOS only is cheaper than building for both iOS and Android, because Android requires separate code and testing. The third is who builds it. A solo developer in a lower-cost country charges differently than a team in San Francisco, and both charge differently than an in-house team you hire full-time.

Key Takeaways

  • A basic app costs $5,000 to $15,000 from a freelancer; a moderately complex app costs $25,000 to $100,000 from a small agency.
  • Building for both iOS and Android costs roughly double building for one platform, because the code must be written separately for each.
  • Features that handle payments, user accounts, or real-time data are the largest cost drivers after platform choice.
  • Ongoing costs — hosting, maintenance, and updates — typically run 15 to 25 percent of the original development cost per year.
  • The cheapest option upfront (a single freelancer) often costs more over time because one person cannot maintain the app alone as it grows.

How complexity affects the price

A straightforward app has one or two screens, displays information that does not change often, and does not require user accounts or payment processing. Examples include a calculator, a flashcard app, or a reference guide. These typically cost $5,000 to $20,000 and take 4 to 8 weeks to build. The developer writes the core logic, designs the interface, and tests it on real devices. There is little back-end work — the app mostly runs on the phone itself.

A moderately complex app has multiple screens, user accounts, and data that syncs across devices or changes based on user input. Examples include a fitness tracker, a note-taking app with cloud backup, or a social app where users follow each other. These cost $25,000 to $100,000 and take 3 to 6 months. The developer must build a back-end server to store data, write code to handle user login and security, and test the app across many devices and network conditions. They also need to plan for scaling — what happens when 10,000 users sign up at once.

A complex app integrates with payment systems, real-time messaging, maps, or machine learning. Examples include a ride-sharing app, a banking app, or an app that uses your camera to identify objects. These cost $150,000 to $500,000 or more and take 6 months to 2 years. The developer must work with third-party services (payment processors, mapping APIs, cloud providers), handle security at a high level, and test extensively because failures are costly. A bug in a payment app can lose money; a bug in a banking app can expose financial data.

Platform choice and the cost of building twice

iOS and Android are fundamentally different platforms. iOS apps are written in Swift or Objective-C. Android apps are written in Java or Kotlin. The logic might be the same, but the code is not. This means building for both platforms costs roughly double the cost of building for one — not quite double, because some planning and design work overlaps, but close enough that you should expect a significant jump.

A straightforward app for iOS alone might cost $8,000. The same app for both iOS and Android might cost $14,000 to $16,000, not $16,000. A moderately complex app for iOS alone might cost $50,000; for both platforms, $80,000 to $100,000. The gap narrows slightly for very complex apps because the fixed costs of planning and infrastructure are spread across more code, but the principle holds: two platforms means roughly two development efforts.

Some developers use cross-platform frameworks like React Native or Flutter, which let them write code once and deploy to both platforms. This can reduce costs by 20 to 40 percent compared to building separately. The trade-off is that cross-platform apps sometimes feel less polished on each platform, because they cannot use every iOS-specific or Android-specific feature. For most business apps, the cost savings outweigh this. For apps where the user experience is the main product (like a game or a photo editor), building separately is often worth the extra cost.

Who builds it: freelancers, agencies, and in-house teams

A solo freelancer or small team (1 to 3 people) charges $50 to $150 per hour in the United States, less in other countries. They are fast and cheap upfront, but they have limits. One person cannot maintain an app alone while also building new features. If the freelancer gets sick or takes another job, your app stops being updated. Freelancers are best for straightforward, one-time projects or for apps that do not need ongoing support.

A small agency (5 to 20 people) charges $100 to $250 per hour and typically quotes a fixed price for a defined project. They have enough people to handle multiple tasks at once — one person designs, another builds the back-end, another tests. If someone leaves, the work continues. Agencies are better for moderately complex apps and for projects where you need a clear timeline and budget. The downside is that you pay for their overhead; a $50,000 project might include $10,000 in project management and coordination costs.

An in-house team — developers you hire as employees — costs $80,000 to $200,000 per year per person in the United States, plus benefits and equipment. This is expensive upfront but makes sense if you plan to build multiple apps or if you need constant updates and new features. You own the code and the relationship with the developers. The downside is that you are responsible for hiring, managing, and keeping them busy. If you only need one app built once, hiring a full team is wasteful.

What features cost the most

User accounts and authentication add $3,000 to $10,000 to a project. The app must securely store passwords (never in plain text), let users reset forgotten passwords, and handle the case where a user logs in on multiple devices. If you want users to log in with Google or Facebook instead of creating a new password, that adds integration work but can actually reduce the total cost because you are using someone else's authentication system.

Payment processing adds $5,000 to $20,000. The app must integrate with Stripe, Square, or Apple Pay. It must handle the case where a payment fails, where a user disputes a charge, or where a refund is issued. It must comply with PCI DSS, a security standard for handling credit cards. This is not optional complexity — if you handle payments wrong, you expose customer data and face legal liability.

Real-time features — notifications, live chat, or live location tracking — add $5,000 to $30,000. The app must maintain a constant connection to a server, handle the case where the connection drops, and sync data across multiple devices when ready. This requires a more sophisticated back-end than a straightforward app that just fetches data when the user opens it.

Integration with external services — maps, weather data, social media, or third-party APIs — adds $2,000 to $15,000 per integration. The developer must understand how the external service works, handle cases where it is slow or unavailable, and keep up with changes to its API. Integrating with one service is straightforward; integrating with five is a significant project.

Ongoing costs after launch

Building the app is not the end of the cost. Once it launches, you must pay for hosting (the servers that run your back-end), maintenance (fixing bugs and keeping the code up to date), and updates (adding new features and adapting to new versions of iOS and Android).

Hosting costs vary widely. A straightforward app with few users might cost $20 to $100 per month on a service like Firebase or Heroku. A moderately complex app with thousands of users might cost $500 to $2,000 per month. A large app with millions of users can cost tens of thousands per month. These costs scale with usage — the more people use the app, the more server power you need.

Maintenance and updates typically cost 15 to 25 percent of the original development cost per year. If you paid $50,000 to build the app, budget $7,500 to $12,500 per year to keep it running. This includes fixing bugs that users report, updating the app when Apple or Google releases a new version of iOS or Android, and making small improvements. If you want major new features, that is a separate project with its own cost.

Some developers offer a retainer — a fixed monthly fee (usually $2,000 to $10,000) that covers a certain number of hours of maintenance and updates. This is predictable and often cheaper than paying hourly for fixes as they come up, but you must use the hours or lose them.

Ways to reduce costs without cutting corners

Start with one platform. Build for iOS first if your users are in the United States or Western Europe (where iPhones are common). Build for Android first if your users are in India, Brazil, or Southeast Asia (where Android dominates). You can add the second platform later once you have revenue or user feedback.

Use existing tools and templates instead of building everything from scratch. Services like Firebase handle user authentication, data storage, and hosting. Payment processors like Stripe handle the complexity of taking money. Mapping services like Google Maps handle location features. Using these services costs money per month, but it is usually cheaper than paying a developer to build the same thing.

Define scope ruthlessly. Write down the features you absolutely need to launch. Everything else goes on a list for later. A common mistake is trying to build the "complete" app on the first try. It is cheaper and faster to launch a straightforward version, get feedback from real users, and add features based on what they actually want. This also reduces the risk that you build something nobody wants.

Hire in lower-cost regions if you are comfortable with time zone differences and communication challenges. A developer in Eastern Europe or South Asia might charge 40 to 60 percent less than one in the United States. The trade-off is that communication is harder, and you have less recourse if the work is poor. Use this approach for straightforward projects where the requirements are clear, not for complex or experimental work.

Frequently Asked Questions

Can I build an app for under $5,000?

Yes, but only if you use a no-code platform like Bubble, FlutterFlow, or Adalo, or if you build it yourself. These platforms let you create straightforward apps by dragging and dropping components instead of writing code. The downside is that you are limited to what the platform allows — you cannot build anything truly custom. For a straightforward business app or a prototype, this works. For anything more complex, you need a real developer.

Why does building for Android cost as much as building for iOS?

Because the code is completely different. iOS uses Swift; Android uses Kotlin or Java. The developer must write, test, and maintain separate code for each platform. Some work overlaps — the design and planning are the same — but the actual programming is two separate jobs. Cross-platform frameworks reduce this cost by 20 to 40 percent, but they have their own trade-offs.

What if I want to add features after launch?

New features cost money, typically $5,000 to $50,000 depending on complexity. A straightforward feature like a new screen or a new filter might cost $5,000 to $10,000. A complex feature like payment processing or real-time notifications might cost $15,000 to $50,000. Budget for this upfront. Many apps fail not because the initial version was bad, but because the developer ran out of money to add features users wanted.

Is it cheaper to hire one developer full-time or pay a freelancer per project?

It depends on how much work you have. One full-time developer costs $80,000 to $150,000 per year plus benefits. If you have enough work to keep them busy, this is cheaper than paying freelancers hourly. If you only have one project, hiring full-time is wasteful. A middle ground is a retainer with a freelancer or small agency — you pay a fixed monthly fee for a certain number of hours, and you can scale up or down as needed.

Do I need to pay for updates forever?

Not forever, but yes for as long as you want the app to work. Apple and Google release new versions of iOS and Android every year. Apps that do not update eventually stop working on new devices. If you stop paying for maintenance, your app will slowly become incompatible with new phones. You can pause updates if the app is stable and you do not need new features, but expect to pay for at least one update per year to stay compatible.
