The cost of developing a mobile application is not a fixed number but the result of concrete decisions about functionality, platforms and the business logic the application must support. For companies in Western and Northern Europe looking for a reliable development partner, the question is rarely just about price — it is about what that price includes, whether the scope is realistic and whether the team delivering the project understands both the technical requirements and the business context behind them. Prolink is a Zagreb-based development studio with over a decade of experience building Android and iOS applications for clients ranging from public institutions and financial organisations to startups and service businesses. Being located in Croatia means we operate inside the EU, default to GDPR-compliant development practices, work in the Central European timezone with no meaningful time-zone gap for clients in the UK, the Netherlands, Belgium, France, Norway or Sweden, and communicate fluently in English and German. Personal meetings are straightforward — Zagreb is under two hours from most Western European capitals by air.
Factors that determine the cost of a mobile application
The number of platforms is the first decision with a direct impact on cost, because developing for Android and iOS simultaneously means double testing, adapting the user interface to each platform's guidelines and managing two distribution channels. Functional complexity determines how many development hours an implementation requires, because user authentication, real-time communication, geolocation, payment integration or biometric login each carries its own technical cost that is not visible at the user experience level. Backend infrastructure is a standard part of every project, including server logic, databases, API layers and security protocols, and its complexity grows proportionally with the number of users and the volume of data the application must process. Push notifications appear to be a simple feature, but implementation that includes targeting user segments, automating delivery according to user behaviour and tracking open analytics requires significantly more development than basic notification sending. Integrations with external systems such as ERP, CRM, payment platforms or IoT devices are most often the largest individual cost segment because they require knowledge of the external system's technical specifications and parallel testing of two independent systems. UI design tailored to the client's specific visual identity costs more than adapting a generic template, but directly affects user retention rates and app store reviews.
Indicative pricing for mobile app development
The prices below are based on project complexity and functional scope, but the final price is always defined after requirements analysis. Pricing is fixed and one-time, with no additional charges for features that should have been included.
| Category | Indicative price | Description |
|---|---|---|
| App without backend | up to 2,000 EUR + VAT | Standalone app with local data storage, no server infrastructure or push notifications. |
| Simple application | 2,000 EUR – 5,000 EUR + VAT | Basic functionality, backend, user registration, content display, push notifications. |
| Mid-complexity application | 5,000 EUR – 12,000 EUR + VAT | Advanced push notifications with user targeting, API integration, data management. |
| Advanced application | 12,000 EUR – 25,000 EUR + VAT | Complex business processes, real-time communication, ERP/CRM integrations, push automation. |
| Complex application | from 25,000 EUR + VAT | Platforms, marketplaces, IoT, high-complexity multi-platform solutions. |
Push notifications as a business tool, not just a technical feature
Push notifications are one of the most valuable features of a mobile application because they allow direct communication with the user without intermediaries and without a per-message cost. Basic implementation that sends a notification to all users is straightforward to develop, but the full value of push notifications is only achieved through segmentation of users by behaviour, automation of delivery based on triggers such as abandoned orders or expiring subscriptions, and analytics tracking which message types drive action. Prolink implements push notifications as part of the broader communication architecture of the application rather than as an isolated module added afterwards, because integration with backend user data determines how relevant the messages are and therefore how effective they are.
Android and iOS, one or two platforms
Developing for one platform means a lower initial cost but excludes the share of the user base that uses the other platform. Ionic, the cross-platform technology Prolink uses for hybrid applications, enables development that covers both platforms with a shared codebase, reducing development and maintenance costs compared to native development for each platform separately. Native development has advantages in terms of performance and access to device-specific capabilities, but carries a higher cost because it requires entirely separate development processes for Android and iOS. The choice of approach depends on project requirements, expected load and budget, and Prolink provides a recommendation only after analysing the specific functional requirements because there is no universally correct solution.
Admin panel as a hidden cost segment
Most mobile applications require an admin panel that is not visible to the end user but is necessary for managing content, users, push notifications and analytics. This segment is often omitted from the initial project estimate because clients focus on the user-facing side of the application and it surfaces only when development is already underway, disrupting timelines and budgets. Prolink defines and estimates the admin panel in the first phase of the project because that is the only way for the final price to be realistic from the first conversation.
Maintenance as a prerequisite for long-term operation
A mobile application is not a one-time delivered product because Apple and Google regularly release new versions of operating systems that can break applications that are not updated. Security patches, compatibility with new OS versions, performance optimisation and new feature development based on user feedback are ongoing costs that must be planned alongside the initial investment. Prolink defines maintenance as a separate service with a clearly agreed scope and price, so there are no surprises after delivery.
What working with a nearshore EU partner actually means
Western European agencies charge Western European rates. Offshore teams outside the EU introduce GDPR complexity, time-zone friction and communication overhead that erodes the cost advantage over time. Prolink sits in a different position: competitive Central European rates, full EU jurisdiction, no data sovereignty concerns, and a team that has been building production applications for over a decade. Fixed-price contracts mean the budget agreed at the start is the budget at delivery. Full IP transfer means the application belongs entirely to the client. Long-term technical support is agreed according to actual needs, without subscriptions or lock-in. If you are evaluating development partners for your next mobile project and want a realistic estimate based on actual scope, contact us — the first conversation commits you to nothing.
Questions about mobile app development costs
How much does it cost to build a mobile app?
Apps without a backend can be built for up to 2,000 EUR, simple apps with backend and push notifications from 2,000 EUR to 5,000 EUR, mid-complexity from 5,000 EUR to 12,000 EUR, advanced from 12,000 EUR to 25,000 EUR, and complex platforms and marketplace solutions from 25,000 EUR upwards. The final price is always defined after requirements analysis.
Is it more expensive to develop for Android and iOS simultaneously?
Cross-platform development using the Ionic framework covers both platforms with a shared codebase, which is more cost-effective than native development for each platform separately. Native development offers performance advantages but higher cost, and the choice between approaches depends on the project's functional requirements.
What is included in the development price?
The price includes requirements analysis, UX/UI design, application and backend infrastructure development, testing on various devices and publishing on the App Store and Google Play. The admin panel, external system integrations and maintenance are defined separately because they depend on the scope specific to each project.
How much does mobile app maintenance cost?
Maintenance cost depends on system complexity and the agreed scope, from security patches and compatibility with new OS versions to new feature development. Applications that are not regularly maintained lose compatibility with new versions of Android and iOS, which can result in removal from app stores.
Why are push notifications important and do they affect the price?
Push notifications enable direct communication with users and are one of the most effective channels for increasing engagement and conversion. Basic implementation is included in simple and mid-complexity applications, while advanced segmentation and push automation based on user behaviour requires additional development defined according to scope.
Does an app need an admin panel?
Most applications require an admin panel for managing content, users and push notifications. Prolink defines and estimates this segment in the first project phase because adding administration retroactively disrupts timelines and increases costs.
How long does mobile app development take?
A simple application can be ready in six to eight weeks, a mid-complexity one in three to five months, and complex solutions require six or more months. The timeline depends on the clarity of defined requirements and the speed of approvals in individual development phases.
Is the price fixed or can it change?
Prolink works exclusively with fixed pricing and the scope is precisely defined before work begins. The only situation in which the price changes is when the client requests features outside the original scope, and that is then defined as a separate requirement with its own price and timeline.
