How Much Does It Cost to Build a Mobile App in 2026?
"How much does an app cost?" is the first question every founder asks — and the one agencies answer most evasively. Here are the actual numbers, the factors that move them, and the traps that quietly double budgets.
The short answer
In 2026, working with a quality agency:
- Simple MVP (one core flow, standard UI, basic backend): $5,000–15,000
- Standard product (auth, payments, chat, admin panel, integrations): $15,000–40,000
- Complex platform (marketplaces, real-time features, custom algorithms, multi-role systems): $40,000–120,000+
Big-city Western agencies often quote 2–4× these numbers for identical scope. Freelancer marketplaces quote less — with dramatically higher variance in what you actually receive.
What actually drives the price
1. Number of screens and flows
An app with 10 screens is not half the work of an app with 20 — but screen count remains the best first-order predictor of cost. Every screen means design, logic, edge cases, and testing.
2. Backend complexity
A read-only content app needs almost no backend. A marketplace needs accounts, listings, search, payments, messaging, moderation, and notifications — the invisible half of your budget.
3. Third-party integrations
Stripe, Google Maps, Twilio, analytics, CRMs: each integration is usually days, not weeks. But custom integrations with legacy or poorly documented systems can consume entire sprints.
4. Cross-platform strategy
Building iOS and Android as separate native apps nearly doubles cost. One Flutter codebase covering both platforms is the single biggest lever for cutting budget without cutting scope — it's why it's our default stack.
5. Design ambition
Template-grade UI is cheap. Custom design systems with motion and polish add 15–30% — and are usually worth it for consumer products where first impressions decide retention.
The costs nobody quotes
- App store accounts: $99/year (Apple) + $25 once (Google)
- Infrastructure: $0–50/month for most MVPs (Firebase/Supabase free tiers are generous), scaling with users
- Maintenance: budget 15–20% of build cost annually — OS updates, dependency upgrades, small fixes
- The rebuild trap: the most expensive app is the one built twice. Cutting corners on architecture at v1 is how $15k projects become $60k projects
How to keep your budget sane
- Scope an MVP ruthlessly. Your v1 needs one core loop done excellently — not twelve features done adequately.
- Choose cross-platform by default. Go native only if you have a specific, named reason.
- Demand fixed pricing on scoped work. Hourly billing on a poorly scoped project is a blank check.
- Ask who owns the code. The answer should be an immediate "you do" — anything else is lock-in.
What a real quote looks like
A serious agency will give you: a fixed price tied to a written scope, a week-by-week timeline, named deliverables, and clarity on what post-launch support costs. If you're getting a single number with no scope document, you're not getting a quote — you're getting an opening bid.
