How much does it cost to build a mobile app?
In 2026, a focused mobile app MVP built by an experienced freelance developer typically costs less than an agency equivalent and ships in a matter of weeks rather than months. Price is driven mostly by scope — number of screens, backend complexity, and whether you need one cross-platform app (React Native) or separate native apps. A simple app costs far less than a multi-role platform with payments and real-time features.
What actually drives the price
The single biggest factor is scope, not “design” or “quality”. A login screen, a list, and a detail view is cheap. The same app plus payments, real-time chat, multiple user roles, an admin panel and offline support is a different project entirely.
- Number of screens and unique flows
- Backend complexity (auth, database, payments, real-time)
- Cross-platform (React Native, one codebase) vs separate native iOS + Android
- Whether you need an admin panel / dashboard too
- Integrations (maps, SMS, push, third-party APIs)
Freelancer vs agency
An agency carries overhead — project managers, sales, account managers — that you pay for on top of the engineering. An experienced freelance developer doing the work directly is usually significantly cheaper for the same result, and you talk to the person actually building your app.
The trade-off is capacity: a solo developer takes one or two serious projects at a time. For most small businesses and startups, that focus is an advantage, not a limitation.
How to keep the cost down
You control most of the budget by controlling scope. The cheapest path to a real app is to ship a focused first version, then add features once it is in users’ hands.
- Start with an MVP — the 2-3 features that prove the idea
- Use React Native + Expo for one codebase across iOS and Android
- Reuse a backend-as-a-service (Supabase / Firebase) instead of custom infrastructure
- Defer “nice to have” features to version 2
Key takeaways
- Scope drives price more than anything else.
- A focused MVP ships in weeks and costs a fraction of a full platform.
- A freelance developer avoids agency overhead for the same result.
- Cross-platform (React Native) is usually the cheapest way to reach both stores.
