How Much Does It Cost to Build an App?

A mobile app in 2026 typically costs $10,000–$40,000 for a simple app or MVP, $40,000–$100,000 for a mid-complexity app, and $100,000+ for something complex with many features and a heavy backend. Like websites, “an app” covers everything from a simple offline tool to a full social platform, so the honest answer is a range. I’m a freelance app developer, and here’s how I break down what actually determines the number.

Key takeaways

• MVP / simple app: $10,000–$40,000. Mid-complexity app: $40,000–$100,000. Complex app: $100,000+.
• The biggest cost drivers are the number of features and screens, the backend and API work, and whether you build native or cross-platform.
• Cross-platform (React Native, Flutter) usually costs less than fully native because it’s one codebase for both iOS and Android — see React Native vs native.
• Start with an MVP. Ship the core idea, validate with real users, then invest in the full build once you know what people actually use.
• Budget for ongoing costs: backend hosting, developer accounts, and maintenance. Apps need upkeep because iOS and Android change every year.

App cost by scope

The clearest way to think about app cost is by scope tier. Here’s the framework I use when quoting.

Scope	Typical range (2026)	Example
MVP / simple app	$10,000 – $40,000	Single-purpose tool, basic accounts, a few screens
Mid-complexity app	$40,000 – $100,000	Social features, payments, real-time data, integrations
Complex app	$100,000+	Marketplaces, heavy backend, multiple user types, custom infrastructure

If you want a number for your specific idea, the project cost calculator will get you a ballpark in a couple of minutes, and you can see my approach on the app development services page.

The MVP: where most apps should start

A minimum viable product is the smallest version of your app that proves the idea works. The point isn’t to cut corners — it’s to focus. You build the two or three core features that define the product, ship it, and learn from real users before spending on everything else. Most MVPs land in the $10,000–$40,000 range, and building cross-platform keeps that number down. This is genuinely the smartest way to spend a first budget: I’ve seen far more money wasted on over-built v1 apps than on MVPs that shipped too lean.

Mid-complexity apps

Once you add real-time features, payments, chat, third-party integrations, or multiple user roles, you’re in mid-complexity territory. The cost climbs because each of those features touches design, the frontend, the backend, and testing. This is where most funded startups and established businesses land.

Complex apps

Marketplaces, apps with heavy backend infrastructure, multiple distinct user types, live video, or serious scale requirements are complex builds. These are multi-month engagements and often involve a team rather than a single developer.

What actually drives app cost

The price isn’t set by one thing — it’s the sum of several. In rough order of impact:

• Features and screens. Every unique screen and feature is design plus frontend plus (often) backend work. Feature count is the number-one driver.
• Backend and API. If your app has accounts, stores data, syncs across devices, or sends notifications, it needs a backend. This is frequently a third to half of the total cost, and it’s the part clients most often underestimate.
• Native vs cross-platform. Building separately for iOS and Android roughly doubles the platform work. Cross-platform shares one codebase. More on this below.
• Design complexity. Custom animations, bespoke UI, and a polished, branded feel cost more than standard components — and often they’re worth it.
• Integrations. Payments, maps, analytics, third-party APIs, and login providers all add hours.
• Testing and QA. Apps run on hundreds of device and OS combinations. Thorough testing is real work and skipping it shows.

Native vs cross-platform: the cost lever

The single biggest architectural decision for cost is native versus cross-platform.

Approach	Cost impact	Best for
Cross-platform (React Native / Flutter)	Lower — one codebase for iOS + Android	Most apps, MVPs, startups, budget-conscious builds
Fully native (Swift + Kotlin)	Higher — two separate codebases	Performance-critical apps, deep platform features

For the large majority of apps, cross-platform with React Native is the cost-effective choice — you ship to both platforms from one codebase, which cuts development time significantly. Fully native pays off when you need maximum performance (heavy graphics, AR, complex device features), but it roughly doubles the platform work. I wrote a full honest comparison in React Native vs native app development.

Freelancer vs agency for apps

Who builds your app affects the price the same way it does for websites. An agency brings a full team — designers, multiple developers, project managers — and the cost reflects that overhead. A senior freelancer costs less for comparable quality on small-to-mid projects because you work directly with the builder. For a large, multi-team app, an agency’s capacity matters; for an MVP or a focused product, a freelancer is usually the better value. I break down the trade-offs in freelancer vs agency and how to hire a web developer (the same principles apply to app developers). You can also compare on the comparison page and see rates on the pricing page.

Ongoing costs of running an app

The build is one-time; running an app is not. Plan for these:

Ongoing cost	Typical range
Backend hosting	$20–$500+ / month (scales with users)
Apple Developer account	$99 / year
Google Play account	$25 (one-time)
Maintenance & updates	Varies — plan for it
Third-party services	Varies (analytics, notifications, etc.)

Maintenance isn’t optional for apps. iOS and Android release major updates every year, and an app that isn’t maintained breaks, gets rejected from the stores, or falls behind. Budget for ongoing upkeep from the start.

How to keep app costs under control

• Start with an MVP. Prove the idea before building the full vision. This is the single biggest lever on total spend.
• Go cross-platform unless you have a specific reason to go native.
• Scope ruthlessly. Separate must-have features from nice-to-haves. Phase two exists for a reason.
• Have your design and content ready where you can — indecision mid-build is expensive.
• Communicate clearly with your developer. Misunderstood requirements are the most expensive kind of rework.

The bottom line

Expect $10,000–$40,000 for an MVP, $40,000–$100,000 for a mid-complexity app, and $100,000+ for a complex one. The drivers are feature count, the backend, and native versus cross-platform. For most people, the right move is to build a focused MVP cross-platform, ship it, and expand based on what real users do.
