The honest answer to “how much does it cost to build a mobile app?” is a wide range: from roughly the price of a small car for a focused first version to the price of a house for a complex, scalable product. What you pay is decided by scope, not by the number of screens. This guide gives realistic 2026 budget ranges, explains what drives them and shows how to get a version one live without overspending.
- Typical ranges: a simple first version often lands around $10,000 to $50,000, a mid-complexity app $50,000 to $150,000, and a complex or enterprise app well beyond that.
- Biggest drivers: features, backend and integrations, number of platforms, design depth and compliance.
- Budget for after launch: maintenance is commonly estimated at 15 to 25 percent of the build cost per year.
- Best way to save: launch a focused MVP on one codebase, then expand with real user data.
Please note: these figures are typical ranges quoted in industry cost guides in 2026, not a NexxusByte quote. Real prices depend heavily on scope, team seniority and region.
Mobile app development cost by type of app
| App type | Typical budget | Typical timeline | Examples |
|---|---|---|---|
| Simple / MVP | $10,000 to $50,000 | 2 to 4 months | Booking, content, internal tool, single main flow |
| Medium complexity | $50,000 to $150,000 | 4 to 8 months | User accounts, payments, admin panel, third-party integrations |
| Complex | $100,000 to $300,000+ | 7 to 12+ months | Real-time features, marketplaces, advanced backend, AI features |
| Enterprise-grade | $200,000+ | 9 to 18+ months | Large user bases, strict security and compliance, many integrations |
Ranges overlap because “an app” is not one product. A beautiful app with one core feature can cost far less than a plain-looking app with a complicated backend.
What actually drives the cost of an app
- Features and screens. Every feature adds design, development and testing. Login, payments, chat, maps, notifications and offline mode are the usual budget movers.
- Backend and APIs. Most of the work in many apps is invisible: databases, servers, user management, an admin dashboard and integrations with payment, CRM or ERP systems.
- Platforms. iOS only, Android only or both. This is where native versus cross-platform changes the bill (see below).
- Design quality. Custom UI, animation and a tested user journey take more time than a standard template. Good UI/UX design is also what reduces rework later.
- Security and compliance. Health, finance and children’s apps carry extra requirements that affect architecture and testing.
- Team location and seniority. Hourly rates vary widely by region and experience, from budget-friendly to premium. A senior team costs more per hour but often finishes faster with fewer defects.
Native vs cross-platform: how it changes the budget
| Approach | Cost | Best for |
|---|---|---|
| Native iOS and Android (two codebases) | Highest | Performance-critical apps and deep device features |
| Cross-platform (Flutter or React Native, one codebase) | Often meaningfully lower, commonly estimated at a third or more below two native apps | Most business apps that need both stores |
| Progressive web app (PWA) | Lowest | Content and simple tools where store presence is optional |
For most businesses that need both iOS and Android, cross-platform is the sensible starting point. We explain the trade-offs in detail in our guide to native vs cross-platform app development.
The costs most quotes do not mention
- Maintenance and updates. Operating system releases, security patches and bug fixes continue forever. A common planning figure is 15 to 25 percent of the build cost per year.
- Cloud hosting and third-party services. Servers, databases, push notification, maps, SMS and payment fees grow with your users.
- App store fees. At the time of writing, the Apple Developer Program is an annual fee and Google Play charges a one-time registration fee. Check the current pricing on each store.
- Content, legal and analytics. Privacy policy, terms, store listings, screenshots and analytics setup.
- Marketing. An app with no promotion gets no installs. Plan for launch marketing and social media marketing.
How to reduce app development cost without hurting quality
- Define one core problem. Build the smallest version that solves it end to end.
- Choose one codebase. Cross-platform frameworks cut duplicated work.
- Cut features, not quality. A polished app with three features beats a clumsy one with twelve.
- Use proven services. Buy authentication, payments and notifications instead of building them.
- Prototype first. A clickable prototype tested with real users is far cheaper than discovering a wrong assumption after development.
- Plan phases. Release version one, learn from analytics and reviews, then fund the next phase.
How to get an accurate quote
Ask every agency for a fixed-scope proposal that lists features, platforms, backend work, design deliverables, testing, the post-launch warranty and a monthly support option. Prefer a team that runs a short discovery phase, because it turns unknowns into a written scope. If you want a second opinion, our mobile app development team can review your idea and give you a phased roadmap.
Frequently asked questions
How much does a simple app cost?
A simple, focused first version commonly lands between about $10,000 and $50,000, depending on features, platforms and design depth.
How long does it take to build an app?
A simple app often takes two to four months. Medium apps take four to eight months, and complex products can take a year or more including testing and store review.
Is it cheaper to build for iOS or Android first?
Building for one platform first is cheaper than both, but a cross-platform build often delivers both stores for less than two native apps, so compare quotes for each route.
Do I need a backend for my app?
Most business apps do, for user accounts, data, payments and an admin dashboard. It is often a large part of the budget even though users never see it.
What does an app cost to maintain?
A common planning rule is 15 to 25 percent of the original build cost per year, covering updates, bug fixes, hosting and compliance changes.
