Cross-Platform App Development Services

We create cross-platform applications for mobile, desktop, and embedded operating systems. We use the Qt framework and other tools to build software solutions for IoT systems and applications for consumer, commercial, and industrial needs.

What we do

If you want your app to run on different platforms equally well, we recommend cross-platform software development. Such programs can be compiled for Android, iOS, Windows, macOS, and Linux with minimal changes. Thanks to a single code base, it takes less time than creating native apps for each OS. The Integra team uses the Qt cross-platform framework to write custom applications in high-performance object-oriented C++ and declarative QML languages.

What’s included

Integra Sources employee is working on a computer and developing a cross-platform desktop app.

Cross-Platform Desktop App Development

We develop cross-platform apps for Windows, Linux, and macOS. Such solutions are more productive than mobile apps because they use PC resources. Desktop applications are more functional than mobile versions, as they can use more peripheral devices. Compared to web applications, desktop programs have the advantage of being able to work without the Internet.

Cross-Platform Mobile App Development

We create cross-platform mobile applications for iOS and Android. With this approach, one can build and bring apps to market faster and reach a broader audience of users across platforms. Creating and updating cross-platform mobile applications is cheaper than developing several native apps for each OS.

IoT App Development

IoT development requires appropriate application software creation. We develop cross-platform applications for IoT systems. Such solutions allow users to receive data from peripherals and control system operations from tablets, computers, smartphones, HMI panels, etc. We develop convenient and understandable user interfaces.

Databases

We design databases and work with various database management systems: PostgreSQL, MySQL, Microsoft SQL Server, Oracle, MongoDB, and MariaDB. We also offer database migration. The team will analyze the existing infrastructure, estimate the risks, and develop a migration strategy by choosing the optimal scenario for each client.

UI/UX Design

The application interfaces we create are convenient and understandable. We design app screens and elements, build predictable navigation, and add useful offline functionality. Finished design prototypes are tested for effectiveness, efficiency, and usability.

Testing and Launch

Testing is one of the key stages of software development. Our software products are subjected to repeated testing at all work stages. We test cross-platform applications on targeted devices to eliminate shortcomings and errors in functionality and adjust the design. Our specialists prepare the necessary program documentation. We can release an application on the App Store, Google Play, and other app stores and distribution platforms.

Frequently Asked Questions

Read this information to better understand the process of cross-platform software development.

What is a cross-platform application?

Cross-platform development allows writing source code that can be compiled for different operating systems with minimal changes. Programmers don't need to rewrite most of the source code for each app version. They only need to set up the build process for a specific OS. Such programs can run on Windows, Linux, macOS, iOS, and Android equally well. Cross-platform development is faster and cheaper than creating native apps for each OS.

How long does it take to create a cross-platform application?

The timing of a project largely depends on its specifics, complexity, scale, choice of components, and logistics. For example, a project audit can take 1-2 months, while AI-based software development usually lasts much longer. We always set realistic deadlines when preparing the spec and stick to the schedule at all project stages.

Do you test applications before handing them over to customers?

Of course! When building cross-platform applications, testing and debugging are mandatory steps. Our Quality Assurance Department will test the programs on all required platforms. After the project is finished, we offer a warranty period during which we will fix any discovered bugs.

What about intellectual property rights?

The cession of intellectual property rights is legislated in our contracts. We also sign a non-disclosure agreement to protect any sensitive information. We will mention your project on our website and other platforms only with your permission.

Can I order your services if I don’t have a clear plan?

Naturally! Our team of qualified analysts will help you shape ideas into a concept, estimate the costs, pick the most suitable technologies, and work out an action plan.

What do I get after the project is finished?

After your application is finished, you get a fully functional product, as well as the source code, technical documentation, and manuals. If required, we will also provide training.

What programming languages do you use?

As a cross-platform application development company, we have experts competent in C++ and QML languages. They are also skilled in C#, Python, Java, and other languages. The choice depends on what functionality you want to implement in your solution.

What technologies do you use for cross-platform application development?

For cross-platform application development, we use the Qt framework.

What to consider when hiring a cross-platform application development company?

The key things to take into account are the domain expertise of the team and their experience in projects similar to yours. The company must not only provide clear cost and time estimation but also justify it in detail. Make sure you check reviews from previous customers and company ratings on Clutch and similar platforms. Also, consider the team's communication skills, as you want to be aware of how the work is progressing.

Who are your customers?

We develop projects for private enterprises and public organizations: small, medium, and large businesses, mining and manufacturing enterprises, startups, healthcare organizations, and enterprises engaged in other industries.
