Our approach: AI-Augmented Development

We develop software using an advanced AI-Augmented Development model.

What does this mean for your business?

Faster Time-to-Market - shortening the time spent on routine development work and automating testing allows us to bring your application to market faster than in the traditional model.

More budget for innovation - by automating repetitive code, our engineers can focus 100% of their attention on unique business features and architecture that build your competitive advantage.

Greater project stability - multi-level, automatic code reviews eliminate errors at such an early stage that the testing and application stabilization phase is reduced to a minimum.

Intelligent AI agents support the software development process at every stage of the team’s work: from pre-project analysis and design, through implementation and code review, to testing. We combine automation and speed with full engineering control, ensuring high quality and consistency of solutions.

Frontier-class models in the development process - in day-to-day programming work, we use the most advanced AI models to support code writing, refactoring, and analysis. We use them where they genuinely improve the quality and pace of the team’s work, especially in highly complex tasks.

Consistent workflow - AI tools operate in the same environment in which your project is created, so the team does not lose time switching between tools. How this works from the technical side is described on the page.

Multidimensional AI code review - before a change is seen by a second developer, it goes through automatic quality and security control. Thanks to this, more mature code reaches the testing phase, and project stabilization is reduced to a minimum.

Technological flexibility and cost control - we do not make your project dependent on a single AI provider. Selecting tools for a specific task allows us to optimize costs and maintain predictable pricing without compromising quality.

Engineering responsibility and security

AI agents support the software development process, but they do not make autonomous architectural decisions or approve code changes without human supervision.

Our approach is based on proven internal architectural foundations, which we continuously develop and standardize. We also progressively implement mature engineering practices in projects delivered for clients, ensuring consistency, predictability, and high quality of the solutions we provide.

Our Proprietary Needs Assessment Process

Benefit from the extensive experience of our designers, analysts, and project managers in conducting the Needs Assessment process and verify your concept of a digital product or service.

Competitive analysis, allowing you to better understand the market

Identification of key features for the Minimum Viable Product (MVP)

Technical feasibility study

Preliminary User Experience (UX) design and overall MVP specification

Cost and timeline estimation

As a result of the Needs Assessment process, you will find out whether a mobile application is an essential element of your business, and if so, we will advise on the optimal technology (native or cross-platform) and you will learn the required budget for its development.

Trust and responsibility are two of Norbsoft's main values. The success of our clients is our success, which is why you can be sure that we will propose the implementation of the application only when we are convinced that our services are necessary for you.

Thorough Approach to the Design Process

If you already have specified expectations regarding the product, the next step is to visualize them and precisely define the technical requirements for all its components.

Creating an appropriate design system will maintain consistency between all elements of the project and accelerate the design work.

If you have a graphic design prepared by your internal team or a creative agency, at Norbsoft we will help verify its accuracy and completeness, and suggest making changes if it is beneficial for your project.

The design process is similar when implementing backend solutions by your own team.

Production of Native Mobile Applications

Norbsoft is one of the few software houses, that has been creating native mobile applications for iOS and Android systems since they became an integral part of smartphones.

We use the latest, proven technologies for each ecosystem, based on scalable architectures. Currently, we are using the Swift and Kotlin programming languages.

We work in two methodologies - in sprints or by dividing the project into milestones - depending on your needs and project requirements.

Cross-platform application development

As a team originating from the development of the most demanding native applications, we offer a unique approach to product development in Flutter, React Native, Kotlin, and Compose Multiplatform.

Our experience allows us to reliably assess when it is worth opting for time and cost savings, and where native support is essential. Thanks to our proficiency in Swift and Kotlin, we are not limited to off-the-shelf libraries - we independently build advanced bridges between cross-platform code and the operating system, ensuring smooth performance and the highest UX quality.

Quality Control

At Norbsoft's office, we have a vast array of test devices, covering all supported versions of operating systems, screen resolutions, and differences in computing power. We ensure 100% certainty that mobile application testing performed by us will result in a reliably functioning product.

As part of mobile application testing, we conduct tests of applications developed by Norbsoft, as well as perform audits of external solutions.

Development of test cases and manual functional testing

Automated tests

Security tests, compliance with OWASP MASVS

Maintenance and SLA

Mobile applications created by Norbsoft under the Fixed Price model are subject to a 12-month warranty.

Every application after its launch requires maintenance and regular servicing. In the absence of intensive in-house application development by a dedicated team, Norbsoft offers our clients an SLA (Service Level Agreement) that ensures shorter response times to bug reports and tickets.

In addition to functional development, at Norbsoft you can also count on:

Adapting applications to new versions of systems and requirements of Google Play and App Store

Refactoring and updating used libraries

Monitoring performance and errors

Valuable Knowledge Transfer

At Norbsoft, we nurture long-term relationships with our clients. With some, we have been working for over 10 years.

When it comes to maintenance and development, not every mobile application requires building technological competencies within the organization. That being said, there are those which, as a result of global business strategies or after achieving great success, clients decide to develop within their own structures.

The client requires, we support project migration processes by providing appropriate source code documentation and functional documentation, as well as by extending the client's new team until it becomes self-reliant.

The proprietary rights to the software we create are transferred to the client.

Modernization of Mobile Applications

If your current mobile application no longer meets business objectives, lags behind the competition, loses existing users, no longer meets legal requirements, or simply does not function properly, it's time to modernize it.

As part of the services offered by Norbsoft, we conduct a process that includes one or more of the following stages:

General Audit

Code Refactoring

UX/UI Modernization

Security Update

The general audit, referred to by us as the Revival Sprint, is time dedicated by our developers, designers, and QA team to familiarize themselves with the product and verify its actual state, resulting in a recommendation for further actions.

Depending on the audit results, at Norbsoft we may propose modernizing the UI itself, refactoring the code (better organizing its structure to reduce the costs of further maintenance and development of the product), or introducing new features.

Research and Prototyping

Creating a unique feature, often constituting a competitive advantage of a mobile application, will not always be straightforward in terms of technical solution.

Features such as custom use of device sensors, connectivity mechanisms, artificial intelligence, or innovative forms of data presentation require prototyping. Thanks to a systematic, iterative approach, prototyping can enable the achievement of the intended effect or allow for withdrawal if implementation within the anticipated budget is not feasible.

At Norbsoft, as part of numerous projects for clients, hackathons, and competency development, we have created applications utilizing Augmented Reality (AR), AI, and Machine Learning in the field of image recognition, as well as rich forms of data visualization using the Unity 3D engine.

Frequently Asked Questions

We are committed to transparent and collaborative cooperation, so we are happy to answer questions and clarify any doubts.

How much does a mobile application cost?

The cost depends on the functional scope and the selected technology. A relatively simple native application for one platform (iOS or Android) starts at approximately PLN 70,000. A cross-platform application (Flutter, React Native) works on both platforms from the outset and is usually 25-40% cheaper than two separate native applications. It is not simply “half the price,” because it requires its own integration layer and a more careful approach to UX on each system. An average-complexity project supporting both platforms typically falls within the range of PLN 150,000 - 400,000, while the most advanced implementations exceed PLN 1 million, regardless of the technological approach.

Write to us to receive an exact, free estimate of your project.

How long does the entire process of creating a mobile application take?

The delivery time depends primarily on the functional scope. Regardless of whether you choose a native approach (iOS and Android developed in parallel) or a cross-platform one (Flutter, React Native, Kotlin Multiplatform), the timeline is usually similar. From the start of work on the graphic design to the publication of the first version in the Google Play and Apple App Store, it takes on average 3–4 months for an MVP and about 6–12 months for the full scope. The choice of technology is always discussed at the Needs Assessment stage - the main criterion is the specific nature of the project and the long-term maintenance cost, not just the implementation time.

How big of a team works on creating a mobile application?

It depends on the technology and the complexity of the project. For a native iOS and Android application, the team usually consists of an analyst, a designer, four developers, a Project Manager, and a tester. In the case of a cross-platform application, the team may be smaller - two or three developers are often sufficient. Regardless of the approach, every project at Norbsoft is led by a dedicated Project Manager and goes through a full quality assurance process.

What billing methods do you use?

We offer various billing models: Fixed Price, Time & Material, and Team Augmentation. Check which one best suits your project or write to us to discuss the details.

Is there an option for you to support my team in just one area of the project?

Yes! We are happy to undertake the design of a user-friendly and secure application, its execution according to the specifications provided by you, or thorough testing of a product developed by another team.

Contact us to discuss your needs in more detail.

Do you advise and consult on mobile application ideas?

Yes, our analysts will conduct workshops with you to understand the needs of your organization. The result will be pre-execution documentation describing the functions of the application and its requirements. Based on such a document, a cost and time estimate of the project can confidently be prepared.

When is it worth choosing a cross-platform application, and when a native one?

It depends on the project goals, not on technological preferences. Cross-platform applications (Flutter, React Native, Kotlin Multiplatform) make sense when cost matters and the functionality does not require deep system integration. Native applications (Swift, Kotlin) are best suited where maximum performance, access to platform-specific APIs, or complex system logic are crucial. Norbsoft delivers both approaches - and as one of the few software houses with over 20 years of native experience, we are able to reliably assess which technology truly serves your project. This is exactly what our Needs Assessment process is for - before any technological decision is made, we jointly analyze business goals, constraints, and the long-term cost of maintenance.

Do you use AI in the software development process?

Yes, we actively develop and implement the AI-Augmented Development practice. We use artificial intelligence support at every stage of the project - from analysis, estimates, and UX/UI mockups, through code writing, to automated testing.

AI tools are integrated directly with our task management system. Thanks to this, we automatically verify the quality and performance of the written code. We are also independent of any specific AI provider, which allows us to flexibly control project costs.

When working on your application, we use only those solutions that we have previously rigorously tested in our internal laboratory.

Does AI-generated code go into production without human supervision?

Definitely not. Artificial intelligence effectively automates routine tasks and significantly speeds up work, but it does not make key decisions.

Every change created with the support of AI goes through exactly the same review and approval process as manually written code - it is approved by an experienced developer before it reaches the repository. The shape of the application in critical areas remains exclusively in human hands. The same principle of full engineering control applies at every stage - from the initial analysis to the final tests. AI is our support, but it is the human who guarantees quality and security.

Are our data and project materials secure when using AI?

Yes, we treat the confidentiality of your data as a priority. We use AI models exclusively in business (Enterprise) modes. This means that none of the content we provide is used to train public models or stored beyond the time necessary to complete the task. All client materials are covered by strict non-disclosure agreements (NDAs), and we limit the scope of information provided to the tools to the absolute minimum. Sensitive and critical data remain under the exclusive, secure control of our team.

How does the use of AI affect the cost and timeline of my project?

Implementing the AI-Augmented Development model directly optimizes the budget and shortens the time to market (Time-to-Market) of the application. Artificial intelligence brings the greatest savings where it allows engineers to skip routine, repetitive stages of work. This results in a shorter timeline and lower cost in three key areas:

- Generation of the base implementation - Based on precise requirements from the analyst, our AI agents are able to quickly create a code skeleton. The developer does not start from scratch, but moves directly to refining the unique business logic.

- Test and QA automation - AI automatically generates and maintains test scenarios. This drastically reduces the time developers would otherwise have to spend writing tests manually.

- Rapid prototyping and automated code review - Most technical errors are detected automatically before the code is even reviewed by a developer.

What does this mean for your budget?

- In the Fixed Price model, this allows us to present a much more competitive final quotation.

- In the Time & Material model, this simply means fewer hours on the invoice for the same stages of work.

- Lower risk of delays - Early error detection protects the project from costly fixes just before deployment.

Will every project be cheaper by a fixed percentage because of this?

No, we do not provide one fixed scale of savings, because the final cost always depends on the unique complexity of your business. AI automates the engineering craft, but it does not replace strategic planning. That is why we always analyze and verify each budget individually.
