Most mobile apps in 2026 fall into three cost bands: a simple app runs roughly $20k–40k, a medium app with real backend and integrations lands around $40k–100k, and a complex, multi-platform product starts at $100k+ and climbs from there. These are industry ranges, not a menu price — the same feature list can double in cost depending on design polish, backend complexity, and how many edge cases you handle properly. If you want to move fast without overspending, a focused cross-platform MVP can start around $20,000, which is where we point most first-time founders.
Below is an honest breakdown of what those numbers actually buy, why quotes vary so wildly, and how to compare them without getting burned.
The short version: cost by app complexity
Complexity is the single biggest lever. Here's how the tiers usually break down.
| App type | Typical features | Typical range | Rough timeline |
|---|---|---|---|
| Simple / MVP | Auth, a few core screens, basic backend, one platform or cross-platform | $20k–40k | 6–12 weeks |
| Medium | Payments, push notifications, third-party integrations, real-time data, admin panel | $40k–100k | 3–6 months |
| Complex | Multiple user roles, offline sync, custom hardware/ML, high scale, both platforms native | $100k+ | 6–12+ months |
A "simple" app is not a low-quality app — it's a focused one. The fastest way to blow past $100k is to try to ship the medium or complex version on day one, before you know what users actually need.
What actually drives the cost
Six things move the number more than anything else.
1. Feature scope
Every screen, form, and state you add is design time, engineering time, and QA time. A login flow sounds trivial until you account for password reset, social sign-in, session handling, and error states. Features compound — a feature that touches payments and notifications and an admin dashboard costs more than the three in isolation.
2. Platforms
Building for iOS and Android natively means, in effect, two codebases. This is the biggest structural cost decision you'll make, and it's why cross-platform matters so much (more below).
3. Backend and infrastructure
A brochure-style app with no accounts is cheap. The moment you need user accounts, a database, an API, file storage, and real-time features, you're building a full backend — often as much work as the app itself. Serverless and managed services keep this leaner than it used to be, but it's rarely free.
4. Design
Off-the-shelf component libraries keep costs down. Custom animations, a bespoke design system, and pixel-level polish push them up. Good UX is worth paying for; gratuitous visual flourish usually isn't, at least not in an MVP.
5. Integrations
Payments (Stripe), maps, analytics, chat, calendars, CRMs — each integration is straightforward on a good day and a multi-day rabbit hole on a bad one, especially where compliance (PCI, HIPAA) or third-party API quirks are involved.
6. Team and seniority
A senior team costs more per hour but usually less per outcome, because they make fewer architectural mistakes you pay to unwind later. The cheapest hourly rate is rarely the cheapest project.
Native vs. cross-platform: where the money goes
This is the decision that most affects your budget. Native means separate Swift/Kotlin codebases for iOS and Android. Cross-platform — in 2026, that overwhelmingly means React Native — means one codebase that ships to both.
| Native (iOS + Android) | Cross-platform (React Native) | |
|---|---|---|
| Codebases | Two | One |
| Relative cost | Higher — you build and maintain twice | Lower — shared logic and UI |
| Best for | Heavy graphics, deep OS/hardware features, max performance | Most business, marketplace, SaaS, and content apps |
| Time to market | Slower | Faster |
| Maintenance | Two teams / two release cycles | One team, one release cycle |
For the large majority of apps — anything that's fundamentally screens, data, auth, payments, and API calls — cross-platform is the pragmatic default. One codebase means you write a feature once, fix a bug once, and ship an update to both stores at the same time. That's not just a smaller upfront bill; it roughly halves your ongoing engineering surface area for the life of the product.
Native still earns its keep for apps built around demanding graphics, real-time hardware access, or platform-specific capabilities where the last 10% of performance and polish is the product. If that's not you, paying for two native codebases is usually spending money to solve a problem you don't have. Our mobile app development work covers both, but we'll tell you honestly which one your project needs.
MVP-first: the cheapest app is the one you don't over-build
The most expensive mistake in mobile isn't hourly rates — it's building the wrong thing at full scale. An MVP (minimum viable product) is the smallest version of your app that delivers the core value and lets real users tell you what matters.
Building MVP-first controls cost in three ways:
- You defer the expensive features until you have evidence they're worth it.
- You reach the market in weeks, not quarters, so revenue or feedback starts offsetting spend sooner.
- You avoid rework — the biggest hidden cost is building elaborate features nobody uses, then rebuilding based on what they actually do.
A focused cross-platform MVP with us starts around $20,000, and for tightly defined scope we offer fixed-scope MVPs from ~$12,000 so you know the number before we start. That's not a stripped-down prototype — it's a real, shippable app that does one thing well. You can read more about that approach on our MVP development page.
Ongoing and maintenance costs
Launch is not the finish line. Apps need OS updates, dependency upgrades, bug fixes, security patches, server costs, and app-store compliance work. The industry rule of thumb is to budget ~15–20% of the original build cost per year for maintenance.
So a $40k app implies roughly $6k–8k/year to keep healthy — more if it's actively growing with new features. Skipping maintenance doesn't save money; it defers it into a larger, more painful bill when something breaks or an OS update ships. Cross-platform helps here too: one codebase means one maintenance stream instead of two.
Don't forget the recurring line items outside development: the Apple Developer Program ($99/yr), Google Play (a one-time $25), plus cloud hosting, push/email services, and any paid third-party APIs. These are usually modest but real.
Why quotes vary so wildly — and how to compare them
If you get three quotes for "the same app" ranging from $15k to $150k, you're not looking at three prices for one thing. You're looking at three different apps that happen to share a description. The variance comes from:
- Scope interpretation — one team assumes 8 screens, another assumes 30.
- Backend assumptions — is the API included, or "your responsibility"?
- Seniority and location — hourly rates vary 5–10x globally.
- What's excluded — QA, project management, design, deployment, and a post-launch window are sometimes bundled, sometimes not.
- Fixed vs. hourly — a fixed bid prices in risk; an hourly estimate can drift.
To compare apples-to-apples, force every quote onto the same footing:
- Give everyone the same written scope — a feature list, target platforms, and rough screen count.
- Ask what's included: design, backend, QA, project management, deployment, and how many weeks of post-launch support.
- Ask native or cross-platform and why — it should match your actual needs, not the vendor's comfort zone.
- Ask who does the work — senior engineers, or juniors with a senior name on the proposal.
- Prefer fixed scope for MVPs so the number is a commitment, not a starting bid.
A quote that's dramatically cheaper usually cut something you'll pay for later — often QA, backend, or maintenance. The goal isn't the lowest number; it's the clearest one.
If you're also weighing your marketing site or web presence alongside the app, our take on Next.js vs. WordPress covers similar cost-vs-fit tradeoffs on the web side.
Frequently asked questions
How long does it take to build an app?
A focused MVP typically takes 6–12 weeks. A medium app with payments and integrations runs 3–6 months, and a complex multi-platform product 6–12+ months. Cross-platform shortens all of these because you're building once instead of twice. Timeline and cost track closely — most of the bill is skilled time.
Is $10,000 enough to build an app?
It can be, if the scope is genuinely small and tightly defined — a single-purpose utility, a validated concept, or a phase-one slice of a larger idea. Our fixed-scope MVPs start from ~$12,000 for exactly this reason. At the $10k mark you should expect a lean, focused app, not a feature-rich product. Be wary of anyone promising a full-featured app for that number; something is being left out, usually QA, backend, or the honest edge cases.
Native or cross-platform — which is cheaper?
Cross-platform (React Native) is almost always cheaper to build and maintain, because one codebase serves both iOS and Android instead of two. Native only wins on cost-per-value when you genuinely need heavy graphics, deep hardware access, or maximum performance. For most business, marketplace, and SaaS apps, cross-platform is the pragmatic and cheaper choice.
What ongoing costs should I plan for after launch?
Budget roughly 15–20% of the build cost per year for maintenance — OS updates, security patches, dependency upgrades, and bug fixes — plus recurring costs for developer accounts, hosting, and any paid third-party services. Maintenance isn't optional; deferring it just converts small ongoing costs into a large future one.
Where to start
If you have a defined idea and a real budget, the highest-leverage move in 2026 is to build a focused cross-platform MVP, get it in front of users, and let real usage guide what you invest in next. That keeps your first number small and your second number smart.
We build senior-led mobile apps with exactly that discipline — cross-platform MVPs from ~$20,000, fixed-scope options from ~$12,000, and no upsell to features you don't need yet. Start with our MVP development service, and get in touch with a short description of your idea. We'll give you an honest range and a clear scope before you commit a dollar.
