How Much Does It Cost to Build a Mobile App?

Search this question and you'll get ranges from $5,000 to $500,000, which tells you nothing. The spread is that wide because "an app" describes both a three-screen booking tool and a real-time marketplace with payments in fourteen countries.

So rather than another range, here's what actually moves the number — and the ongoing cost that sinks more app projects than the build price ever does.

The five things that set the price

1. Feature surface. Not screen count — distinct capabilities. Accounts, payments, chat, offline sync, maps, video, and notifications each carry their own build, test, and edge-case burden.
2. Platforms. iOS only, Android only, or both. This is the single biggest lever you control, and we'll come back to it.
3. The backend. An app that only displays content is cheap. An app with user accounts, a database, an admin panel, and an API is a full software product that happens to have a phone client. Most of the cost is often here, not in the app itself.
4. Design. A templated interface is fast. A distinctive, branded, animated one is a real design engagement — and for consumer apps it's usually worth it, because it's most of what users judge you on.
5. Integrations. Every third-party system — payment processor, CRM, ERP, legacy API — adds work that scales with their quality, not yours.

Realistic 2026 ranges

Working with an experienced studio, cross-platform, production-ready, backend included:

That entry point surprises people, so it's worth being precise about what makes it possible — and what it isn't.

A $5,000 app is real when the scope is genuinely focused: one clear job, a modest number of screens, a single cross-platform codebase, and a managed backend rather than infrastructure built from scratch. The saving comes from scope discipline and reusing solved problems, not from skipping tests, security, or store compliance. Those aren't line items you can remove and still have something you can put your name on.

What it isn't: a container for "we'll figure out the rest later." If the feature list grows during the build, you're no longer buying the essential tier — you're buying the next one in instalments, usually at a worse price than if you'd scoped it properly up front.

The clearest signal you've outgrown the entry tier is a second user type. One user doing one job stays cheap; the moment you add admins, roles, or permissions, you're in standard territory and the estimate should say so honestly.

The cost nobody budgets for

Here's the part that matters more than the build quote, and it's the thing we most often have to say out loud to founders:

A mobile app is a subscription, not a purchase. Budget 15–25% of the build cost every year, forever, or plan to watch it break.

Websites degrade gracefully — an unmaintained site from 2023 still loads today. Mobile apps do not. Both Apple and Google ship a major OS version every year, deprecate APIs on their own schedule, and periodically change store requirements. Miss those and your app doesn't merely look dated: it can be rejected at update time, break on new devices, or be removed from the store entirely.

One important caveat on that percentage: it's a reasonable guide for mid-size and larger builds, but the annual cost has a floor that doesn't scale down. OS releases arrive on the same schedule whether your app cost $5,000 or $500,000, and a store account costs the same either way. On a small build, plan for maintenance as a real fixed line item rather than a small fraction of a small number — proportionally it will be the largest it ever is.

That floor exists even if you never add a single feature:

• OS compatibility updates for two platforms, annually.
• Store policy compliance (privacy disclosures, permissions, SDK requirements).
• Dependency and security patching.
• Backend hosting and monitoring.
• Developer accounts — Apple is a yearly fee, Google a one-time registration.
• Support for the users you now have.

The honest implication: if you can't fund year two, reconsider starting year one. An abandoned app is worse than no app, because it's a live, findable, broken representation of your brand.

The biggest lever on the number

Building fully native means two codebases, two sets of expertise, and roughly 1.6 to 1.8 times the cost of one cross-platform build — plus double the maintenance, forever.

For most products — dashboards, marketplaces, productivity, SaaS companion apps — a well-built cross-platform app is indistinguishable from native to the user. Going native is worth it when platform-specific capability is the product: heavy AR, low-level camera or audio work, sustained high-frame-rate graphics. We break the decision down properly in native vs cross-platform development.

If your budget is tight, this is the first lever to pull — well before you start cutting features that make the product worth using.

Where you can safely cut

• Launch on one platform. Pick where your users actually are and add the second later, funded by revenue.
• Cut features, not quality. Five polished features beat fifteen shaky ones, and cost less to maintain.
• Use off-the-shelf for solved problems — auth, payments, analytics, push infrastructure.
• Defer the admin panel. For the first few months you can often run operations from database tooling instead of custom screens.

Where not to cut: security, the data model, and testing on real devices. Those are the ones that come back at three times the price.

Getting a number you can actually plan with

Any quote given without a scoping conversation is a guess. A real estimate needs your feature list, your platforms, your integrations, and your launch date — and it should arrive as a fixed scope with milestones, not an open-ended hourly arrangement where the risk is entirely yours.

If your app is really a product with a phone client, the economics look a lot like software in general — worth reading alongside what a SaaS MVP costs.

We scope mobile work as fixed-fee milestones, including a written year-two maintenance plan so the ongoing cost is visible before you commit. See how we handle mobile and SaaS development, or get in touch for an estimate on your app.
