How much does a mobile app cost in 2026 — a realistic budget breakdown (MVP vs product)

"How much does it cost to build a mobile app?" is a question whose honest answer is: it depends — but that answer is useless when you have to plan a budget. Below we break the cost down by stage, show realistic ranges for 2026 on the Polish market and explain what specifically drives the price up. No marketing "from PLN 9,999", and no scaremongering about millions.

Disclaimer: all amounts are net ranges for delivery by a Polish software house and are indicative. The actual quote depends on scope, level of polish and non-functional requirements. Treat these numbers as a map, not an offer.

What the cost really depends on

Before the numbers — five variables that determine the order of magnitude:

• Functional scope — how many screens, how complex the logic, how many edge cases.
• Number of platforms — iOS only, Android only, or both; plus web where relevant.
• Backend — does it exist, or does it have to be built (API, database, admin panel).
• External integrations — payments, maps, BLE, the client's systems, third-party services.
• Non-functional requirements — security, performance, compliance (GDPR, accessibility, regulated industries).

Two apps with the same number of screens can differ threefold in cost if one is a simple catalogue and the other handles payments, offline mode and hardware integration.

Project stages and how the budget splits

Cost is not "a developer writes code". A typical project breaks down into stages — and it is worth knowing that development itself is usually about half the budget, not all of it:

Hourly rates of Polish teams in 2026 fall roughly in the PLN 120–250/h net range, depending on seniority and the cooperation model. Those rates translate into the figures below.

Ranges: MVP vs mature product

An MVP (Minimum Viable Product) is not "a worse app" — it is the narrowest scope that genuinely validates the idea on the market. A mature product is that MVP developed iteratively with further features, scale and polish.

If you hear a quote along the lines of "an app like Uber for PLN 40k" — that is a warning sign. That amount will not cover the backend, payments, real-time geolocation and the testing such a product requires.

What specifically drives the cost up

This is where budgets "swell" relative to the first estimate. The most common multipliers:

Payment integrations

Payments are not "one button". They bring: choosing an operator (Przelewy24/Stripe/PayU), Apple Pay and Google Pay, handling refunds and complaints, standards compliance (PCI-DSS sits with the operator, but the integration still demands rigour), recurring payments. Realistic overhead: +PLN 15,000 – 40,000, more with subscriptions and multi-party settlements.

BLE and hardware integration

Bluetooth Low Energy, IoT, peripheral devices — one of the most underestimated areas. The reason: testing has to be done on physical devices, behaviour differs between phone models, and debugging is time-consuming. Overhead: +PLN 30,000 – 100,000 and more, depending on the number of devices and protocol complexity.

Compliance and regulatory requirements

GDPR is the baseline. On top of it come digital accessibility (WCAG — increasingly required, also by regulation), regulated industries (healthcare, finance, public sector), security audits, data retention and encryption. Overhead: +PLN 20,000 – 80,000, and in regulated sectors it can become the dominant budget item.

Other typical multipliers

• Backend from scratch: +PLN 50,000 – 200,000 (API, database, authorisation, scaling).
• Offline mode and synchronisation: +PLN 30,000 – 80,000 (resolving data conflicts is hard).
• Admin panel: +PLN 30,000 – 80,000.
• Advanced animation / highly polished UX: +10–30% on the frontend portion.

Native or cross-platform — how it affects the price

• Cross-platform (Flutter, React Native) — one codebase for iOS and Android. Usually 20–40% cheaper for a comparable scope, with faster time to market. A good fit for most business applications.
• Native (Swift / Kotlin) — two separate teams/codebases. More expensive, but justified with heavy hardware use, demanding performance (games, AR) or when you need the newest system features from day one.

For most MVPs, cross-platform is the default, rational choice on cost.

Hidden costs — the ones forgotten at quoting time

An app does not end on release day. Budget for:

• Developer accounts: Apple Developer (USD 99/year), Google Play (USD 25 one-off).
• Infrastructure: servers, databases, cloud services, push notifications — from a few hundred to a few thousand zloty per month, growing with scale.
• Maintenance and development: realistically 15–20% of the initial budget per year for system updates (every year new iOS/Android releases can "break" a working app), fixes and small enhancements.
• Support and monitoring: handling production errors, analytics, responding to store reviews.

Omitting these items is the most common reason why a "finished" project suddenly costs money again.

How to read a quote and avoid overpaying

• Demand a breakdown by stage and feature, not a single "for the app" figure. A breakdown exposes assumptions and lets you trim scope.
• Start with an MVP. Build the narrowest scope that gives you market data, then develop what works. Paying up front for the full vision is the most expensive way to discover that some features were not needed.
• Ask what is NOT included — backend, testing, store deployment, maintenance.
• Beware of extremes. A quote significantly below market usually means omitted scope that will come back as a "change request". A very high quote with no scope to justify it is also a signal to talk.

Summary

In 2026 the realistic cost of a mobile app starts at around PLN 80–150k for a simple MVP, PLN 150–300k for an extended MVP, and PLN 300–700k and up for a mature product. The biggest multipliers are payments, hardware integrations (BLE) and compliance. Add maintenance of roughly 15–20% of the budget per year. The key to spending sensibly is a quote broken down by stage and a start from an MVP.

At Mobilesoft we quote transparently — broken down by stage and feature, so you know what you are paying for and what you can trim.
