How much does it cost to build a mobile app? The honest answer is a range, not a number — anywhere from roughly $15,000 for a simple app to $300,000 or more for a complex platform. What decides where you land is not the framework or the platform; it is the scope you commit to and the decisions you make before a single line of code is written.
What actually drives the cost
Two apps with the same number of screens can differ tenfold in price. The variables that move the number most are how many features you truly need, whether there is a custom backend behind the screens, how polished the design has to be, and how many third-party services you integrate with.
- Feature count and complexity — a to-do app and a ride-hailing app are not the same project.
- Backend and APIs — user accounts, data sync, and real-time features add server-side work.
- Design fidelity — a template-based UI is cheap; a bespoke, animated brand experience is not.
- Integrations — payments, maps, messaging, and third-party APIs each add build and test time.
- Platforms — one cross-platform app costs far less than two separate native builds.
Ballpark ranges for 2026
- Simple app (one platform, few screens, no backend): roughly $15,000–$40,000.
- Mid-range app (accounts, backend, a few integrations): roughly $40,000–$120,000.
- Complex app (real-time, multiple integrations, high design polish): $120,000–$300,000+.
- Ongoing costs: budget 15–20% of the build per year for maintenance, updates, and hosting.
The most expensive app is the one you build twice — once on a guess, and again once you know what users actually need.
How to spend less without regret
The cheapest route to a working app is almost always a focused first version: build the one workflow that proves the idea, launch it to real users, and let their behaviour — not a spec document — decide what gets built next. Cross-platform frameworks like React Native and Flutter cut cost further by serving iOS and Android from one codebase. Spend on the parts users touch every day, and defer everything else until the app has earned it.
