These include, but are not limited to, such modern frameworks as:
We take your groundwork and create a market-ready cross-platform app based on your needs while you focus on product and company growth. Or we develop an app from scratch starting with visualizing the app’s concept and composing architecture based on the peculiarities of targeting platforms and your business needs. From there, we create a comprehensive app and provide ongoing support including app store release and on-demand enhancements.
Our turn-key team strengthens your cross-platform development capabilities by working as an autonomous or internal engineering force and filling the gaps in specific technology expertise. By doing so, we bring ideas and solutions to the table to accelerate engineering velocity and time to market.
Start small, win big. Before investing in a full-fledged cross-platform application development, test your product idea for viability and make a test run to receive valuable user feedback to gain an edge on the competition. This helps make a great showcase for investors and bulletproof your pitch.
We use our extensive experience and technical know-how to help you avoid bottlenecks when creating new products—choosing the best suited tech strategy and planning security measures before you start the cross-platform development process. Our experts analyze the business idea, conduct market and audience research, create a detailed roadmap, and design proper architecture to ensure smooth operation now and in future enhancements.
If you already have a product that no longer meets your business needs or doesn’t work the way you want it to—plummeting profits, low user retention, or not scalable enough. In this case, our team will conduct a thorough audit of your product, encompassing business processes, architecture, UX appeal, and more, to help develop a well-elaborated plan for the required enhancements.
Cross-platform technology provides a consistent user experience across operating systems creating the whole ecosystem and allowing you to reach and retain a wider audience regardless of the devices they use.
We know how to build powerful mobile and tablet applications, progressive web apps (PWA), Android and Apple wearable apps, and TV apps that uncover new possibilities for your target audience. We provide cross-platform solutions for the following mobile and web platforms:
1
We form a vision of the product based on technical and business requirements and your target audience—discovering where the solution will be used and what’s essential to your users and composing functional/non-functional requirements. We conduct preliminary research, outline the expected scope of work, and set milestones before kicking off the project.
2
Knowing all cross-platform limitations, we create the best fitted UI/UX as close to native experience as possible. We assemble layouts and create style guides and clickable prototypes to experience the future app and develop a solution, where each button meets the specific needs of the user.
3
This involves elaborating the software architecture with required features and design. Besides cross-platform app development, we setup back ends and implement third-party APIs and integrations with other systems.
4
We polish the application prior to release with deep, multi-level QA testing, identifying and fixing issues and fine-tuning functionality. The comprehensive QA phase helps save you time and money by preventing any potential issues that would otherwise lead to major glitches and loss of user engagement.
5
We support and further improve the application after properly deploying it to app stores. Our skilled developers implement the extended functionality and provide ongoing support and enhancements.
The benefit here is from sharing a unified app business logic and up to 80% code reuse to target multiple platforms simultaneously: mobile Apple and Android, smart TVs, and even smart watches.
Cross-platform applications are 20–40% faster to create and deploy to app stores, and use far fewer resources than two separate native solutions.
Cross-platform app development cuts project costs without sacrificing end-product functionality or native-like user interfaces.
These help boost your internal collaboration, enhance operational efficiency, and enable fast real-time access to all essential data whenever you need it while keeping the app secure.
Grow your online sales and improve buyer retention and engagement by staying in your customer’s pocket. In addition, you can enhance the way your personnel interact with customers by empowering them with a cross-platform tool for productive work.
If you already have a fitness or health-related business, you can widen your presence and reach your target audience faster, improving lifetime value (LTV) by engaging with them via cross-platform mobile solutions.
Improve your customers’ and drivers’ mobile experiences with robust cross-platform applications that make the ride experience smooth and transparent for both parties.
Cross-platform applications introduce an affordable way for sustainable growth of the transportation industry by bringing transparency and trust to suppliers and distributors.
We build highly secure and resilient fintech apps that enable a customer-centric approach and boost customer experience across multiple platforms while automating anti-fraud processes, enabling real-time tracking and increasing security.
We create apps for eLearning to enhance digital education by ensuring students can access materials and improve results whenever they have time, regardless of the device they use.
Let your users improve personal efficiency beyond desktop and web apps by employing cross-platform mobile development services.
Cross-platform app development is just the first step to realizing the ultimate work tool when emerging technologies can give it a new edge:
Enhance your cross-platform applications with intelligent features that automate routine processes, improve user experience, and expand the application functionality.
Connect your cross-platform app to a robust product analytics solution to make data-driven predictions, gain insights on user behavior, and mitigate risks.
Cross-platform applications can achieve the best performance and efficiency when hosted in the cloud. Cloud apps are designed for growth and rapid scalability.
These immersive technologies bring users unique and memorable experiences within the app and can create a tangible, competitive advantage on the market.
We really care about project success. At the end of the day, happy clients watching how their application is making the end user’s experience and life better are the things that matter.

There is no single “best” option—the optimal choice for cross-platform app development depends on factors like specific business goals, scalability needs, and target audience, as each tool has its own strengths and peculiarities. Based on a detailed framework comparison:
We can help you choose the right technology to match your long-term CI/CD and security requirements.
02/
The cost is highly variable, but cross-platform development is generally 10–30% more cost-effective upfront than building separate native apps. A reliable estimate for cross-platform development depends heavily on the app’s complexity, with factors like advanced features, design, third-party integrations, and ongoing maintenance.
03/
Cross-platform vs native app development—the right decision is rooted in your particular project’s needs and limitations, not the technology itself. Each approach excels in different scenarios.
Native apps cannot be outrun in terms of performance, feature complexity, security, and user experience, but building them requires more time and effort (and costs, respectively).
Cross-platform applications may not have the same performance and complexity level, yet they are up to 40% quicker and cheaper to release and maintain.
04/
Yes, migration to a cross-platform stack is possible and becoming increasingly common. However, it’s not a direct translation but an incremental adoption, where the new cross-platform code is gradually integrated into the existing native app in order to mitigate risks and maintain app functionality throughout the process.
05/
Our experienced cross-platform developers ensure native-like performance by strictly following technical best practices tailored to the chosen framework. This involves leveraging the platform’s strengths or creating dedicated native modules to handle performance-critical tasks. Our approach combines optimized coding, efficient resource management, and rigorous cross-platform app testing. By focusing on time-tested principles, our team delivers high-speed, scalable applications with performance close to native apps.
06/
Yes, our commitment extends beyond the launch date. We offer comprehensive post-launch support packages, including predefined SLA terms for bug fixes, performance monitoring, and critical issue resolution. After deployment, our continuous CI/CD pipelines remain active, enabling rapid, seamless updates and security patches. This ensures your app’s reliability and superior scalability in the long run.
