How much does it cost to build an app?

There's no honest single number, but there is an honest way to think about it. Here's what really moves app cost, and how to get a quote you can trust.

A simple, well-scoped app typically costs in the low-to-mid five figures; a mid-complexity app with a real backend and both platforms runs mid-five to low-six figures; and a complex or regulated app clears six figures. But those ranges are almost meaningless without scope, because app cost is driven by complexity — features, integrations, and backend work — not by the number of screens. The more precisely the app is specified, the tighter and lower the quote.

What drives the cost

Six factors move an app's price far more than screen count:

• Feature complexity. Real-time updates, chat, video, live maps, and anything with shared live state are expensive. Static content and simple forms are cheap.
• Integrations. Each third-party system — payments, calendars, CRMs, messaging, analytics — is a connection to build, test, and keep working as those systems change.
• The backend. Accounts, data storage, sync, notifications, and business logic frequently cost more than the visible app. Much of an app's price is invisible.
• Platforms. Fully native iOS plus Android is close to two builds. A cross-platform framework can serve both from largely one codebase, trading some native polish for a lower cost.
• Design. A distinctive, well-crafted experience takes design hours; a generic template does not, and users can usually tell.
• Compliance and security. Payments, health or financial data, and regulated categories add non-optional engineering and review cost.

Cost by app type

As planning-stage orientation only — every one of these swings with scope:

• A focused utility or content app (one clear core loop, minimal backend, few integrations) sits at the low end.
• A transactional or account-based app (logins, a backend, payments, a couple of integrations, both platforms) sits in the middle.
• A marketplace, social, or real-time app (matching, live data, chat, heavy integrations) sits at the high end.
• A regulated app (health, finance) carries a compliance premium on top of whatever its features would otherwise cost.

An app "like Uber" or "like Instagram" is not a starting point for a quote — those are mature products with years of investment. The buildable version is a scoped MVP of the one core loop, which costs a fraction of the finished platform people picture.

Why estimates vary so much

When founders get quotes that are three-times apart for the "same" app, the cause is almost never dishonesty. It is ambiguity. A vague requirement forces each builder to guess at what you meant and price in the risk of guessing wrong. One shop assumes the simplest interpretation; another assumes the most complex; both are protecting themselves. A precise specification — screens, flows, and acceptance criteria — collapses that spread, because there is nothing left to assume.

Ongoing costs after launch

The build price is not the whole cost. A live app is a product you run:

• Hosting and infrastructure — scales with usage.
• Third-party services — APIs, messaging, mapping, and analytics often bill per use.
• Payment processing and app store fees — a percentage of revenue.
• Maintenance — bug fixes, plus keeping up with new OS versions and security patches, which is not optional.
• Support — real users generate real questions.

A common planning rule is to budget a meaningful percentage of the original build cost per year for ongoing maintenance and improvement. Treat it as a line item from the start, not a surprise.

How to lower cost without gutting the product

You can reduce cost without cutting the value that matters:

• Scope to the core loop. Build only what delivers the core value once; defer everything else. See MVP scope: what to cut.
• Go cross-platform if native polish isn't a core differentiator.
• Phase the build. Ship the MVP, learn from real users, and fund later phases from evidence instead of assumption.
• Specify precisely. The single biggest lever — a clear PRD both lowers the quote and prevents the change orders that blow up budgets mid-build.

What you should not cut to save money is the planning itself. Skipping validation or scope to save weeks is how a cheaper build becomes a total loss.
