How Much Does a Mobile App Cost in 2026? Real Market Ranges

The cost of a mobile app depends above all on the number of screens, the complexity of the backend, and the number of integrations. On the Polish market in 2026, the going ranges are PLN 40–120k net (≈ $11–33k) for an MVP, PLN 120–400k (≈ $33–110k) for a mid-complexity app, and PLN 400k+ (≈ $110k+) for a full-scale product. Maintenance typically runs 10–20% of the build cost per year.

That is the one-paragraph answer. The rest of this guide explains where these numbers come from, why two quotes for the same idea can differ tenfold, and what artificial intelligence has actually changed in 2026 — including where lower prices are already visible. Every figure comes from publicly available, dated sources: price guides published by Polish software houses and industry research from 2025–2026. You will not find our price list here — this is a guide to the market, not an offer.

Why quotes differ by a factor of ten

For the same app brief you can receive a quote of PLN 15k and a quote of PLN 150k in Poland. Both are “real” — they simply describe two different products. The market splits into two tiers that rarely say so out loud.

The budget tier — freelancers and small teams — advertises apps from a few thousand to about PLN 30k. In price lists published in 2026 you can find offers from as little as PLN 1.2–3k for a simple React Native app, or promises like an “MVP for PLN 15–30k in 2–4 weeks”. At that price you usually get a templated interface, minimal or no backend, and a narrow testing scope. For validating a simple idea, that can be a rational choice.

The software-house tier starts at roughly PLN 40–60k net for an MVP and includes UX design, a dedicated backend, testing, and store publication. The ranges published in 2026 — compiled with dates in the table below — start at PLN 40–65k for a React Native MVP, and more typically from about PLN 60k.

The spread is not new — the industry has described cases for years where quotes for the same project differed by as much as 1000%. So the first question when reading a quote is not “how much” but “what exactly is inside”.

What drives the price of a mobile app

An app quote depends on five factors: the number of screens and user scenarios, backend complexity, the number of third-party integrations, the scope of design work, and the number of platforms. A feature list alone is not enough — two apps with the same features can have entirely different architectures and costs.

• Screens and scenarios. Every screen means design, implementation, and testing. An app with 6 screens and a single user path is a different project from one with 30 screens and three user roles.
• Backend. User accounts, data storage, an admin panel, synchronization — usually the single largest budget item. An app with no server of its own can cost several times less.
• Integrations. Payments, maps, push notifications, CRM/ERP systems. Price lists published in 2026 give indicative per-feature add-ons: login and accounts +PLN 5k, payments +PLN 6k, real-time chat +PLN 8k, offline mode +PLN 7k.
• Design. A templated interface versus a bespoke design with user research is a difference in the low tens of thousands of złoty — in market price lists, dedicated UX/UI is typically a +PLN 8k add-on and premium design about +PLN 15k.
• Platforms. iOS and Android built separately (native) or one codebase (React Native, Flutter) — more below, because that decision is worth 30–40% of the budget.

It also helps to know how a budget spreads across phases. In a typical project it looks like this: workshops and analysis 5–10%, interface design about 15%, implementation over half the budget, testing about 15%, release about 5%.

One warning: according to the GoodFirms survey (March 2026), scope creep during a project typically adds 10–25% to the budget. A solid workshop phase up front is cheaper than adding features mid-build.

How much does building an app cost — 2026 ranges

So how much does building an app cost in 2026? In the software-house tier: a simple MVP most often runs PLN 40–120k net, a mid-complexity app — with user accounts, payments, and an admin panel — PLN 120–400k, and a full-scale product with multiple integrations goes beyond PLN 400k.

These ranges are not our opinion — they are what Polish companies themselves publish in 2026:

Behind these figures sit hourly rates: in price lists published in 2026, a team hour most often runs PLN 150–350 net, depending on composition and seniority. That is consistent with labor costs: according to the justjoin.it and No Fluff Jobs reports from the turn of 2025/2026, a senior mobile developer on a B2B contract costs PLN 22–27k a month. For context, Clutch (August 2026) puts most US agency rates at $100–250/h — roughly two to three times the Polish level for comparable seniority.

Timelines: a simple MVP takes 6–12 weeks, a mid-complexity app 3–6 months. Clutch data (August 2026) puts the average full app project at about 11 months, with most reviewed projects in the $10–50k range.

React Native or native — a decision worth 30–40% of the budget

One codebase in React Native or Flutter instead of two separate native apps cuts the build cost by roughly 30–40% — international analyses from 2025–2026 give 20–45% depending on complexity. The difference extends to maintenance: 2026 market estimates put yearly upkeep of a React Native app at PLN 10–15k versus PLN 20–30k for two native apps.

Native still makes sense for games, sensor-heavy apps, and extreme performance requirements. For most business apps — bookings, marketplaces, early-stage fintech, internal tools — cross-platform is the default, cheaper choice in 2026. This is how we build mobile apps — one codebase, both platforms, shipped under the client's store accounts.

Has AI made building an app cheaper?

Yes — though unevenly. Simple apps and MVPs got cheaper the most: by 20–40% versus 2023 according to 2026 market compilations, and a typical project costs about 10–25% less today. Interestingly, hourly rates in Polish IT keep rising (+6–12% a year) — projects got cheaper, not hours: AI simply cuts the number of hours, above all in the coding itself.

Adoption is not in question: according to the DORA report (Google Cloud, September 2025, ~5,000 respondents), 90% of engineers use AI at work, and more than 80% report a productivity increase; Stack Overflow (July 2025, 49,000 respondents) puts adoption at 84%. GoodFirms (March 2026) reports 91% of software companies using AI in their delivery process.

Measurement is only now catching up with practice. The latest METR study (February 2026) — randomized, on experienced developers working with agentic tools in their own real codebases — measured speedups of 4–18%, biggest where most of the work is: prototypes, repetitive code, and tests (on the most complex tasks McKinsey estimates the gains more modestly). Most importantly, the trend points clearly up: a year earlier the same methodology found no gains at all, the tools improve quarter to quarter, and the DORA report links AI adoption to more frequent releases. In 2026, AI's impact on delivery speed is real and visible in projects.

Lower prices now show up not only in offers, but in data. The benchmarking firm ISG reported in July 2025 that market prices of application-maintenance and related IT-services contracts fell by 25–30% thanks to AI. According to McKinsey (State of AI, 2025), 56% of organizations using AI in software engineering report cost decreases. On the agency market, negotiating an “AI discount” has become the norm: clients may ask for 50–70%, and realistically get 20–30% (2026 data). And Y Combinator startups build products with teams of a few people where most of the code is written by AI. One caveat: simple builds and maintenance are getting cheaper fastest — complex, custom projects hold their price for now.

Where does the size of the possible saving come from? A project's cost structure is roughly 40–30–30: about 40% of the budget goes to planning, analysis, and design, about 30% to the coding itself, and about 30% to testing, fixes, and getting the whole thing into the stores. AI compresses the middle slice hardest — for teams working maturely with AI, by as much as two-thirds — which translates into roughly a 20% saving on the whole project:

In practice, part of that dividend comes back to the client as a lower quote, and part as more product: the same budget now fits more features, better testing, and faster iterations, and you see the first working prototype after a week, not a month. The condition remains discipline — AI-generated code needs the same reviews and tests as any other (45% of Stack Overflow 2025 respondents admit debugging AI code can take longer than they expected). A well-run project today is both cheaper and better than two years ago.

What about building it yourself with AI? Lovable, Bolt, Replit

Tools like Lovable, Bolt, and Replit build a working application from a text description for roughly $25–100 a month. For validating an idea, an investor demo, or an internal prototype, this is the cheapest route on the market and we take it seriously — Lovable reached half a billion dollars in annual revenue by May 2026, and about 80% of its users are not developers.

The line runs at a production product: accounts, payments, and real user data. Veracode (2025) found that 45% of AI-generated code contains vulnerabilities from the OWASP Top 10; the typical failures are unsecured API endpoints and disabled database protections. In July 2025, Replit's agent deleted a client's production database during a code freeze. Fixing such apps became its own service category in 2026 — the market calls it “vibe code rescue”.

The rational path looks like this: validate the idea with an AI tool for a few hundred złoty, and once there is traction — build the production version with a team that takes responsibility for security and maintenance. We wrote about this at length in the vibe coding hangover.

How much does adding AI to an app cost

In 2026, AI features are their own budget line, not a free add-on. A simple feature built on a ready-made API — an assistant, summaries, content classification — adds the equivalent of roughly PLN 20–100k (≈ $5–25k) to a build budget, according to published international price guides. An advanced chat over company knowledge (RAG), with permissions and integrations, costs several times more.

Then there is the running cost: every model call is billed. API prices in August 2026 start at about $1 per million tokens (Claude Haiku 4.5; Claude Sonnet 5 — $3, the GPT-5 class — from $1.25), which at real traffic means anywhere from tens to thousands of dollars a month. Since August 2, 2026, the EU AI Act's transparency rules also apply: users must know they are talking to an AI, and synthetic content must be labeled. More on our approach: adding AI to an existing product.

The cost of maintaining a mobile app

Maintaining a mobile app typically costs 10–20% of the build cost per year — for a PLN 100k app, that is PLN 10–20k every year. The first year tends to be more expensive, up to 40–50%, with post-launch fixes and the first big updates. It is the most commonly skipped item in budget conversations — and the most common source of disappointment a year after launch.

What the figure covers:

• OS updates. Apple and Google ship new iOS and Android versions every year; an app that does not keep up starts breaking on new devices.
• Servers and infrastructure. From about PLN 200 to over PLN 2k a month at typical scale; the cost grows with the user base and the amount of data.
• Developer accounts and commissions. The Apple Developer Program costs $99 a year, a Google Play account — a one-time $25. On in-app sales the stores take a commission — and 2026 brought major changes here: Google Play cut its standard rate from 30% to 20% (and to 10% on the first $1M of revenue and on subscriptions; effective in the EEA from June 30, 2026), while Apple announced on August 18, 2026 a new EU model — including a 5% Core Technology Commission from October 1, 2026 and 15% for small businesses in the Small Business Program.
• Monitoring, security, and incremental development. Error tracking, security patches, UX fixes based on how users actually behave.

The global industry norm (CISQ) is 15–20% of the build cost a year — the Polish 10–20% sits in the same band. Technology makes a difference here too: one React Native codebase usually means a clearly lower yearly cost than maintaining two separate native apps. And there is good news: maintenance is exactly where AI is cutting prices fastest — per ISG's 2025 benchmarks, market prices of such services fell 25–30%.

Hidden costs and how to read a quote

A reliable app quote contains the scope (what exactly will be built), the assumptions (what must hold for the price to hold), a list of what is out of scope, a timeline with milestones, and rules for pricing changes. If any of these is missing, comparing the numbers alone is meaningless.

What else to check before you sign:

• Net or gross. B2B quotes in Poland are net — add 23% VAT to every figure in this article (neutral for companies, not for consumers).
• Who owns the code. IP transfer and repository access belong in the contract, not in a verbal promise.
• Maintenance from day one. Ask for the cost of a year of maintenance at the offer stage — vendors differ here more than on the build price.
• Regulatory compliance. GDPR as always, and since August 2026 the AI Act too, if the product ships AI features. Compliance belongs in the quote, not in a later addendum.
• A change reserve. If the market norm for scope creep is 10–25%, plan that reserve into the budget instead of pretending there will be no changes.

Frequently asked questions

How much does a mobile app MVP cost in Poland?

In 2026, software houses most often price a mobile app MVP at PLN 40–120k net (≈ $11–33k). Cheaper offers (PLN 15–30k) usually mean a templated interface and a minimal backend. The final price is decided by scope: screens, backend, and integrations. We cover how to plan the product itself in the MVP playbook.

How long does it take to build a mobile app?

A simple MVP takes 6–12 weeks, a mid-complexity app 3–6 months. According to 2026 Clutch data, a full app project averages about 11 months. AI clearly shortens the prototyping stage, but changes far less across the full delivery cycle.

How much does maintaining a mobile app cost?

The market norm is 10–20% of the build cost per year — for a PLN 100k app, that is PLN 10–20k a year. The first year tends to cost more (up to 40–50%), with post-launch fixes, OS updates, and the first new features.

Will AI make my app cheaper?

Yes, moderately. Simple apps and MVPs got cheaper the most (20–40% versus 2023), and a typical project costs about 10–25% less today — coding is about 30% of a project's cost, and that is the part AI compresses hardest. Hourly rates keep rising, and part of the dividend comes back as wider scope and higher quality.

What does the price of a mobile app depend on most?

On scope: the number of screens, backend complexity (accounts, data, an admin panel), and the number of third-party integrations. Design (template or bespoke), the technology choice, and security requirements matter too. A feature list is only the start of a quote.

Can I build an app myself with AI tools?

For validating an idea — yes: tools like Lovable or Bolt cost around $25–100 a month and let you build a prototype fast. For production — carefully: according to Veracode, 45% of AI-generated code contains security vulnerabilities, and fixing such apps has become a service category of its own.

What next

The cheapest moment to ground a budget in reality is a conversation about scope, before any code exists. An hour spent on what truly belongs in the first version can move a quote more than the choice of vendor.
