"How much does an app cost?" is the wrong first question. The right one is: what are you actually building, and for whom? A simple booking app and a real-time marketplace with payments are both "apps" — but they sit at opposite ends of the cost spectrum. Here's how the real drivers break down.
The biggest cost driver: scope, not platform
Native vs. cross-platform matters less than people assume. What actually moves the budget is feature complexity — real-time data, payments, offline support, third-party integrations, and custom UI all add engineering time regardless of which framework you choose.
Typical ranges by project type
A simple MVP with core screens and basic logic often lands in the lower tens of thousands. A mid-complexity consumer app with accounts, payments, and notifications sits in the mid-tens to low hundreds of thousands. Enterprise or marketplace apps with complex backends, compliance needs, and multiple integrations can run well into six figures.
Where budgets quietly blow out
The most common overruns come from scope creep after development starts, underestimating backend and API work, and skipping QA until the end. Locking a clear scope before development — and testing continuously, not just at the finish line — is the single biggest lever for staying on budget.
How to budget realistically
Start with an MVP scope that tests your core assumption, get a fixed-scope quote against that specific list of features, and treat anything beyond it as a phase two decision made with real user data in hand. At Adverve, we scope mobile projects this way — a clear number for a clear list of features, not a vague estimate for a vague idea.
