How Much Does It Cost to Build an App in 2026?.

Quick Answer: In 2026, a simple mobile app costs $10,000-$25,000, a mid-complexity app with accounts, payments, and a backend runs $25,000-$75,000, and complex products — marketplaces, social platforms, AI features, real-time anything — start at $75,000 and climb past $250,000. Cross-platform frameworks like Flutter cut 30-40% versus building iOS and Android separately. Plan another 15-20% of the build cost per year for maintenance.

"How much does it cost to build an app" is the first question every founder and business owner asks us — and most pricing articles answer it with ranges so wide they're useless, written by people who haven't shipped an app in years.

We build and maintain apps every week. Here's what things actually cost, what moves the number, and where budgets go to die.

App Development Cost by Complexity

A few real-shaped examples to anchor those ranges:

• A booking app for a service business — schedule, pay, get reminders: usually lands in the $25,000-$50,000 band.
• A two-sided marketplace — buyers, sellers, payments with escrow or splits, reviews, messaging: $75,000-$150,000 to do properly, because you're really building three products (two user experiences plus admin).
• An internal operations app that replaces paper and spreadsheets: often $15,000-$40,000, and frequently the fastest payback of anything on this list.

What Actually Drives the Cost

1. How many platforms — and how you build for them

Building native iOS and native Android means two codebases, two teams, two QA cycles — roughly 1.7-1.9× the cost of one platform. Cross-platform frameworks changed that math. We build with Flutter: one codebase that ships to iPhone and Android with native performance, which typically saves 30-40% on the build and nearly half of ongoing maintenance. (More on why in our guide to the benefits of Flutter app development.)

When does native still win? Heavy AR, very specialized hardware access, or platform-first experiences. For 90% of business apps, cross-platform is the financially sane answer.

2. The backend nobody sees

The app on the phone is half the product. Accounts, data, payments, notifications, and admin tools all live on servers — and backend work is routinely 40-50% of a project's budget. When a quote seems too cheap, the backend is usually what got hand-waved.

3. Design

Template UI is cheap; custom design that makes people trust you with their credit card is not. Real UX work — flows, wireframes, visual design, the unglamorous empty states and error screens — runs $5,000-$25,000 depending on scope. It's also the highest-leverage money in the budget: design problems found in Figma cost 10× less to fix than design problems found in code.

4. Integrations and the long tail

Payments (Stripe), maps, calendars, CRMs, SMS, analytics — each integration is days, not hours. AI features deserve their own line item: a well-scoped AI capability (chat, summarization, smart search) adds $10,000-$50,000 depending on how deeply it touches your data.

The Hidden Costs That Surprise First-Timers

• App store accounts: Apple charges $99/year, Google Play $25 once.
• Infrastructure: servers, databases, file storage, and push services typically run $100-$1,000+/mo as you grow.
• Maintenance: OS updates, dependency patches, bug fixes, small improvements — budget 15-20% of the build cost annually. This isn't optional; iOS and Android each ship major updates yearly, and unmaintained apps rot fast. (Our support plans start at $499/mo and exist precisely because of this.)
• App store review cycles: plan for review time and at least one rejection-and-fix round on first submission — we handle submission for clients because the process has teeth.

How to Spend Less Without Getting Burned

1. Scope an MVP ruthlessly. Launch with the one workflow that proves the business, not eleven features. Most successful apps we've built shipped v1 with 40% of the original wishlist — and half of the cut features were never missed.
2. Go cross-platform. One Flutter codebase instead of two native ones is the single biggest legitimate cost saving available.
3. Use bought infrastructure. Stripe for payments, Firebase or managed auth for accounts, off-the-shelf chat SDKs. Custom-building solved problems is how budgets double.
4. Phase the roadmap. Ship, measure, then fund phase two from evidence instead of guesses.

And the false economy to avoid: the $5,000 offshore quote for a $50,000 spec. We regularly inherit those projects at month eight — no documentation, no tests, a backend held together with hope. The rebuild costs more than doing it right once would have. If a quote is 5-10× below the others, you're not comparing the same product.

What We Charge

Our app development projects start at $10,000 for well-scoped MVPs, with ongoing support from $499/mo. iOS and Android from one Flutter codebase, UI/UX design included, backend and APIs built in-house, app store submission handled. You get a fixed quote after a free scoping call — not an estimate that doubles mid-project.

FAQ

Can I build an app for under $10,000? Sometimes — if it's truly simple and you use cross-platform with bought infrastructure. Below ~$5,000, you're buying a template or a prototype, not a product.

How much does it cost to maintain an app? Plan 15-20% of the original build cost per year. A $40,000 app should budget $6,000-$8,000 annually for updates, fixes, and OS compatibility.

Web app or mobile app — which is cheaper? A web app is usually 30-50% cheaper to launch (one platform, no store review) and is often the right v1. If your users need push notifications, camera, GPS, or home-screen presence, go mobile. Our take: many businesses should start with a web application and add mobile once usage proves out.

How long does it take to build an app? Simple: 6-10 weeks. Medium: 3-5 months. Complex: 5-9+ months. Adding developers compresses some of that, but discovery, design, and app-store review don't parallelize.

Do I need both iOS and Android at launch? With Flutter you get both for marginal extra cost, so usually yes. If you're forced to choose, pick where your specific audience lives — US consumer spending skews iOS; field/operations teams often skew Android.
