Cross-Platform App
Development Company

Building top-quality mobile apps since 2009. Hire a leading cross-platform developer to release an app that attracts, engages, and retains users.

Cross-platform development with
React Native

We use the most advanced frameworks on the market with in-house solutions to deliver amazing cross-platform apps.

Accelerate time-to-market

Leveraging the power of React Native development services, we create a single codebase for all platforms. On top of speeding up delivery, our team uses a refined Agile process that allows us to build apps in a more efficient way. Thus, you can predict the results in a volatile market.

Save costs

Tapping into the cross-platform approach reduces development costs by 30%-50% compared to native apps. We use customizable UI elements and ready-made components. This Product Development Framework (PDF) from MindK yields an extra 20% of cost savings.

Exceed user expectations

React Native renders components as native platform widgets, resulting in high performance and a truly native look and feel. Our testing process includes performance tuning to ensure your app is fast and responsive.

Focus on your core business

We take all the technical worries off your shoulders. We understand the business goals and work as an extension of client teams rather than a typical software development provider.

    How it works

    Here's a brief overview of the process we use as a cross-platform mobile app development company.


    Our team engages with you to understand the vision, goals, and problems to solve. This isn't just about the app. It's about how the app fits into the larger business ecosystem. We sketch out a strategy that aligns with your objectives, focusing on user needs and market demands.


    Designers craft intuitive and aesthetically pleasing interfaces, prioritizing seamless UX. This phase is collaborative and iterative. We refine the design based on your feedback and user testing. At the same time, we lay out the technical blueprint, select the right technologies, data structures, and APIs. This ensures your app is scalable, maintainable, and secure.

    Development and testing

    We break the project into manageable sprints. Each one ends with a tangible deliverable. Our developers, testers, and project managers work in concert to deliver polished features. QA engineers test across multiple devices and platforms, hunting for bugs and assessing usability.

    Improvement & support

    MindK guides you through the launch process, managing submissions to app stores. We stand by you, gathering user feedback, monitoring performance, and making iterative improvements. Technology evolves, and so will your app.

      • What is cross-platform app development?

        Cross-platform mobile app development services let us craft an app for both Android and iOS users from the same codebase. Imagine speaking two languages fluently, with the effort of learning just one.

      • Is cross-platform development worth it?

        This hinges on your requirements. If cost and time-to-market are critical, cross-platform app development is a great choice. If you aim for exceptional performance, native feel, and complex features – it’s usually better to go for native apps.

      • Why choose React Native for my app development?

        React Native is like a Swiss Army knife for app development — versatile and efficient. It speeds up the development process, slices down costs, and ensures your app feels right at home on any device.

      • What’s the typical cost and timeline for a cross-platform project?

        Timing varies with your app’s complexity. Generally, brace for a few months from the first sketch to launch. The cost will also vary from $50,000 to $300,000 and more.

      • How do you ensure the app performs well on both Android and iOS?

        Through a cocktail of rigorous testing on a fleet of devices and a keen eye on performance metrics, we tailor your app to perform like an Olympic athlete—stellar performance, no matter the platform.

      • What is your approach to app security?

        We follow the AWS well-architected framework to ensure app security and compliance. Encryption, secure coding practices, and regular security audits are just part of our arsenal.

      • How do you handle updates and maintenance post-launch?

        MindK is ready to tune up anything that needs attention. We ensure your app stays in peak condition with regular updates and maintenance. Our offshore cross-platform app making service also equips your app with analytics to provide a clear view of how users are engaging and help you thrive.
