Our full-cycle cross-platform mobile app development process covers everything from initial concept and UX design to deployment and post-launch support. We're your reliable partner at every stage of cross-platform development.

Accelerated Development Timeline

Develop for multiple platforms simultaneously rather than sequentially. Our cross-platform approach typically reduces development time by 30-40%, helping you reach your market faster and stay ahead of competitors.

Significant Cost Reduction

Save up to 50% on development costs compared to building separate native apps. One codebase means fewer developers needed, streamlined testing processes, and simplified maintenance - all without sacrificing quality.

Consistent Brand Experience

Ensure your users have the same high-quality experience regardless of their device. Our cross-platform solutions maintain consistent UI/UX across iOS, Android and web platforms, strengthening your brand identity.

Easier Maintenance & Updates

Implement changes and bug fixes across all platforms simultaneously. With a single codebase, your app maintenance becomes more efficient, reducing long-term support costs and ensuring all users receive updates concurrently.

Near-Native Performance

Enjoy performance that rivals native applications. Using modern frameworks like React Native and Flutter, we build cross-platform apps that leverage native components to deliver smooth animations, fast load times, and responsive interfaces.

Polish software craftsmanship meets cross-platform innovation

With 10+ years of experience in cross platform mobile development, our Polish team combines technical excellence, transparent communication, and agile methodology. We've delivered 200+ successful projects for clients across 15+ countries, from startups to enterprises. As an offshore cross-platform app developing service, we provide exceptional value without compromising quality.

What is cross-platform mobile development and how does it differ from native development?
Cross-platform mobile development is the process of building applications that work on multiple operating systems (iOS, Android, Windows) from a single codebase. Unlike native development, which requires separate codebases for each platform, cross-platform development uses frameworks like React Native or Flutter to write code once and deploy everywhere. This approach significantly reduces development time and costs while maintaining near-native performance.
What cross-platform technologies do you specialize in?
We specialize in React Native and Flutter for mobile applications, Electron for desktop applications, and Progressive Web Apps (PWAs) for browser-based solutions. We select the technology based on your specific requirements, considering factors like performance needs, platform-specific features, and long-term maintenance.
How much can I save by choosing cross-platform development over native?
Typically, clients save 30-50% in development costs when choosing cross-platform over native development. This savings comes from writing and maintaining a single codebase instead of multiple ones, requiring fewer specialized developers, streamlining the testing process, and simplifying ongoing maintenance and updates.
Will a cross-platform app perform as well as a native app?
Modern cross-platform frameworks like React Native and Flutter deliver performance very close to native applications. They use native components for rendering UI and can access device features through native bridges. For most business applications, users won't notice any difference. Only extremely performance-intensive applications like 3D games or specialized hardware integrations might benefit significantly from purely native development.
What is your development process for cross-platform projects?
Our process follows agile methodology with 2-week sprints. We begin with discovery and planning, create wireframes and prototypes, then progress through development with regular client reviews. We implement comprehensive testing on multiple devices, handle app store submissions, and provide post-launch support. Throughout the process, you'll have a dedicated project manager and access to our project management tools for complete transparency.
Do you provide ongoing maintenance and support after the app is launched?
Yes, we offer flexible maintenance packages to ensure your application continues to perform optimally. These include regular updates for OS compatibility, performance optimization, bug fixes, and implementation of new features. We can work on a retainer basis or through specific maintenance agreements depending on your needs.
How do you handle app updates across multiple platforms?
One of the key advantages of cross-platform development is simplified updates. When we implement changes or fixes, they automatically apply to all platforms. For app store submissions, we handle the specific requirements of each platform, ensuring a smooth update process for both iOS and Android versions simultaneously.
What makes your Polish software house different from other development companies?
We combine Western European quality standards with competitive Central European rates. Our team features senior developers with 5+ years of experience in **application mobile cross platform** development, excellent English communication skills, and extensive experience working with international clients. We're in a similar time zone to Western Europe, making collaboration seamless. Additionally, Poland's strong technical education system and thriving IT sector ensures we stay at the cutting edge of development practices.
