Building a mobile application in 2026 is no longer just about creating a few screens and publishing them in the App Store. For most startups and companies, it means building a complete digital product: backend infrastructure, APIs, admin dashboards, integrations, automation and increasingly AI functionality.
That is why the question “how much does a mobile app cost?” has many different answers. The pricing structure of a simple MVP is completely different from a marketplace, SaaS platform, booking system or AI application.
At Softech Services, we design modern mobile apps, SaaS platforms and operational systems for startups and companies. In this article, we explain the realistic costs of mobile app development in 2026 and what truly impacts the budget.
Why most mobile app pricing articles are misleading
Many online articles answer the pricing question very vaguely: “from 20k to 500k”. The problem is that they rarely explain why the differences are so large.
In reality, the biggest cost drivers are backend systems, architecture, integrations, payments, AI, scalability and automation complexity. The number of mobile screens itself is often only a small part of the entire product.
How much does an MVP mobile app cost?
An MVP, or Minimum Viable Product, is usually the first version of a startup or digital product. Its purpose is not to build a full enterprise platform immediately, but to validate the market and acquire early users.
A typical MVP includes authentication, user profiles, basic backend infrastructure, an admin panel, several screens and App Store / Google Play deployment.
In 2026, a realistic MVP mobile app usually costs between 40,000 and 120,000 PLN.
The biggest startup mistake is trying to build too much too early. A strong MVP should be simple, fast and focused on one core user problem.
Startup mobile applications
Once the product grows beyond a basic MVP, additional complexity appears: payments, user roles, operational systems, notifications, integrations, dashboards and automation.
This category includes marketplaces, delivery apps, booking systems, fintech products, social apps and SaaS platforms.
In practice, these projects often range from 120,000 to 450,000 PLN.
Backend systems, scalability and product architecture heavily influence pricing. Poorly designed systems often require expensive rewrites later.
Marketplace mobile apps — why are they so expensive?
Marketplaces are among the most expensive mobile products because they effectively combine several products into one ecosystem.
A typical marketplace requires a customer app, partner or seller dashboard, backend APIs, payments, moderation systems, logistics workflows and operational dashboards.
As a result, marketplace apps often start around 250,000 PLN and can exceed 900,000 PLN.
A good example of a complex operational product is Foodeli — last-mile logistics and delivery, where the mobile app was only one layer of a much larger logistics ecosystem.
SaaS mobile apps
More SaaS products now include not only mobile applications, but also large web dashboards and operational backend systems.
This includes CRM platforms, operational systems, booking products, field-service tools and AI automation systems.
In such projects, the mobile app is only the interface for a much larger ecosystem.
The cost of building a SaaS ecosystem may range from around 180,000 PLN to well above one million.
A strong example is Fire safety equipment service management system, combining applications, backend systems, operations and administration workflows.
Booking apps and reservation systems
Booking systems appear simple at first glance, but they are actually among the most technically demanding product categories.
They must support calendars, availability logic, payments, synchronization, user roles and often dynamic pricing.
That is why booking applications often cost between 150,000 and 700,000 PLN.
An example of this category is Premium yacht charter platform in Dubai.
AI mobile apps
AI applications are one of the fastest-growing categories in technology. However, many companies incorrectly assume that simply adding ChatGPT creates an AI product.
Real AI products require data infrastructure, workflow automation, memory systems, vector search, language model integrations and scalable backend architecture.
As a result, AI applications often range from around 180,000 PLN to well over one million.
In larger products, AI backend and infrastructure costs may exceed the cost of the mobile frontend itself.
React Native vs Flutter vs Native
The choice of technology significantly impacts project pricing and future development.
React Native is currently one of the strongest options for startups and SaaS because it enables faster development and shared architecture with web frontends such as Next.js.
Flutter performs well for highly custom interfaces, but has a smaller ecosystem and more difficult hiring.
Native Swift and Kotlin development is the most expensive approach, but may be necessary for fintech, advanced device integrations or performance-critical products.
Backend — the biggest hidden cost
Most people think about mobile apps mainly in terms of screens and UX/UI. In reality, backend systems are often the most strategic part of the entire product.
Modern backends handle APIs, business logic, authentication, payments, data, storage, queues, notifications, integrations, AI and scalability.
Backend architecture determines whether the product will remain stable and scalable as the user base grows.
Integrations — the most underestimated layer
Integrations may represent 20–40% of the total project.
Common integrations include Stripe, Apple Pay, Google Maps, ERP systems, CRM tools, OpenAI, Firebase and logistics providers.
Every integration increases complexity and future maintenance requirements.
App Store and Google Play — hidden operational costs
Publishing an app is much more than uploading a build. Companies must also handle reviews, privacy policies, analytics, monitoring, crash reporting, screenshots, release management and ASO.
Maintenance after launch is also frequently underestimated.
Mobile app maintenance
Mobile applications require ongoing maintenance: library updates, iOS and Android compatibility, monitoring, security, backend support and infrastructure maintenance.
Realistically, annual maintenance often represents 10–25% of the original project value.
What does a modern mobile stack look like?
Modern products commonly use React Native, Expo, Next.js, Node.js, NestJS, PostgreSQL, Prisma, Redis, Docker and cloud infrastructure.
This approach enables faster development and stronger scalability.
Examples of modern mobile products
A good example of a modern app connected with backend operations, booking and workflow systems is Gizo — mobile equipment rental app.
Projects like this show that modern mobile apps are part of larger operational ecosystems, not just isolated frontends.
Summary
In 2026, mobile app pricing depends primarily on backend systems, architecture, integrations, scalability and overall product complexity.
The most expensive projects are usually not the ones with the largest number of screens, but the ones designed without proper architecture.
Today, a successful mobile app combines UX/UI, backend engineering, automation, AI, infrastructure and business strategy.
If you are planning a startup, SaaS platform, marketplace or booking system, it is worth starting with a properly designed MVP and scalable product architecture.
