FAQS

Learn More About Our Universal and Cross-Platform Development Services

There is no universal pricing structure to develop a cross-platform mobile app. There are several elements, including app complexity, features, design requirements, and backend infrastructure.

Estimated Cost Ranges

  • Simple Cross-Platform Apps: Typically range from $20,000 to $40,000. These apps include basic features like user authentication, simple UI, and minimal backend integration.
  • Moderately Complex Apps: With functionalities such as real-time data synchronization, third-party integrations, and custom UI/UX, costs can range from $40,000 to $80,000.
  • Highly Complex or Enterprise-Level Apps: Featuring advanced capabilities like AI/ML integration, extensive backend systems, and high scalability requirements, development costs can exceed $100,000.

Factors Influencing Cost

  • App Complexity
  • Design Requirements
  • Backend Infrastructure
  • Maintenance and Support

We specialize in cross-platform development using frameworks like React Native and Flutter, enabling efficient development with a single codebase for both iOS and Android platforms.

The timeline for developing a cross-platform mobile app varies based on the project's complexity, feature set, and specific requirements. While exact durations can differ, here are general estimates:

Estimated Development Timelines

  • Simple Apps (MVPs or basic utilities): Approximately 2–4 months.

  • Moderately Complex Apps (e.g., eCommerce platforms, social networking apps): Around 4–6 months.

  • Highly Complex or Enterprise-Level Apps (featuring real-time functionalities, extensive integrations, or advanced security requirements): Typically 6–12 months or more.

We leverage frameworks to expedite development by enabling a single codebase for both iOS and Android platforms.

Choosing between native and cross-platform depends on your goals, project scope, and available resources. Here is when cross-platform makes the most sense:

  • Accelerated Time-to-Market: Launch faster on both iOS and Android with a shared codebase using frameworks like React Native or Flutter.

  • Cost Efficiency: Save on development and maintenance by building once for all platforms.

  • Consistent User Experience: Ensure a uniform look and feel across devices to boost brand consistency and user satisfaction.

  • Simplified Maintenance: Update and fix issues across all platforms at once with a single codebase.

  • Broad Audience Reach: Reach iOS and Android users simultaneously without doubling development efforts.

  • Resource Optimization: Leverage existing web development skills (like JavaScript) to speed up the build process and reduce onboarding.

We build both cross-platform and native apps, helping businesses choose the right approach based on their unique needs.

Native app development is often the preferred choice over cross-platform solutions in scenarios where performance, user experience, and access to platform-specific features are paramount.


Key situations where native development stands out:

  • Performance-Critical Applications: For apps with high-end graphics, real-time processing, or complex animations (like gaming or AR/VR), native ensures top-tier speed and responsiveness.

  • Access to Platform-Specific Features: Apps that require deep hardware integration—like advanced cameras, biometrics, or custom sensors—benefit from native’s direct access to platform APIs.

  • Superior User Experience (UX): By following each platform’s design standards, native apps offer smoother, more intuitive experiences that feel natural to users.

  • Enhanced Security Requirements: Apps dealing with sensitive data (e.g., healthcare or finance) can leverage stronger, platform-level security and compliance features.

  • Offline Functionality: Native apps handle local storage more efficiently, ensuring reliable performance even without internet connectivity.

  • Faster Adoption of New Features: Native apps can quickly integrate the latest OS updates and capabilities, keeping your product current and competitive.

Whether you go native or cross-platform, we will help you build a solution that’s efficient, reliable, and aligned with your business goals.

Yes, it is possible to build desktop applications using cross-platform development frameworks. 

Several frameworks enable our developers to create applications that run seamlessly across multiple desktop operating systems, including Electron, Tauri, Flutter, and React Native with Extensions.

The frameworks facilitate the development of applications that can operate across various platforms.

Cross-platform app development offers numerous advantages for startups and small to medium-sized enterprises (SMEs), particularly those operating with limited resources and aiming for rapid market entry. 

Key Benefits:

  • Cost Efficiency: Developing a single application for multiple platforms reduces the need for separate development teams, thereby lowering overall costs.
  • Faster Time-to-Market: With a unified codebase, development and deployment processes are streamlined, enabling quicker launches across platforms. 
  • Wider Audience Reach: Cross-platform development ensures that applications are accessible to users on various devices and operating systems, maximizing market exposure without additional development efforts.
  • Consistent User Experience: Maintaining a uniform look and feel across platforms enhances user satisfaction and reinforces brand identity. 
  • Simplified Maintenance: Managing a single codebase simplifies updates and bug fixes, allowing for simultaneous improvements across all platforms. 
  • Ideal for MVP Development: For startups looking to validate their product ideas quickly, cross-platform development is well-suited for creating Minimum Viable Products (MVPs).

By embracing cross-platform development, you can optimize your resources, accelerate growth, and deliver high-quality applications that meet the evolving needs of users.

Cross-platform development is generally more cost-effective than building separate native apps. Here is a concise breakdown:

  • Single Codebase Efficiency: Developing one codebase for multiple platforms reduces development time and costs.
  • Lower Development Costs: Cross-platform development can save approximately 30–40% compared to native development, as it avoids the need for separate teams and codebases for iOS and Android. 
  • Faster Time-to-Market: A unified codebase allows for quicker deployment across platforms, accelerating the launch process.
  • Simplified Maintenance: Updates and bug fixes can be implemented simultaneously across all platforms, reducing long-term maintenance efforts.

Cross-platform development offers significant cost savings and efficiency benefits, making it an attractive option for businesses aiming to reach a wider audience without incurring the higher expenses associated with native app development.

Cross-platform apps have significantly improved in performance, thanks to frameworks like Flutter and React Native. For many business applications, they offer performance that is nearly on par with native apps. However, native apps still hold an edge in certain areas:

  • Performance-Intensive Applications: Native apps are better suited for tasks requiring heavy graphics processing or complex animations, such as gaming or AR/VR applications.

  • Access to Platform-Specific Features: Native development allows for seamless integration with device-specific features and APIs, providing a more tailored user experience.

  • Optimized User Experience: Native apps can fully leverage the UI components and design guidelines of each platform, resulting in smoother interactions and faster load times.


We leverage deep expertise in React Native, Flutter, and modern frameworks to craft high-performance cross-platform apps tailored to your business goals.
