    Frequently Asked Questions

    We understand that you might have questions while getting started with Mobile App development.
    Don’t worry, we’ve answered them here.

    In cross-platform app development, an app is built for multiple platforms (i.e. both iOS and Android) using a single cos base. In contrast, native app development is about building an app for a specific platform (either iOS or Android).

    When you are in the quest of choosing the best cross-platform app development framework, there are various factors that you need to analyze. When performance is your top priority, Go for React Native or Flutter. Customization becomes way too easy with Flutter while React Native is ideal for developers who code in JavaScript. Ionic is a good option when it comes to rapid app development, while Cordova is suitable for simpler apps but may lag in performance compared to the others.

    The best thing about Hybrid Mobile App Development is that it takes the same code to develop apps for all platforms. This helps in saving a lot of your time and cost giving you a competitive edge in terms of scaling your application.

    Cross-platform app development can benefit your business in multiple ways which are listed below:

    • Cost Saving: Reduce development time and cost by developing and deploying the app once across multiple platforms.
    • Wider audience reach: Expand your reach by targeting both Android and iOS users.
    • Faster marketing time: Launch your app quickly by fastening the development process by reusing code.
    • Better User Experience: Maintain consistency by keeping a uniform look and feel across both platforms.
    • Improved ROI: Harness maximum return on investment by reducing costs and increasing reach.

    With React Native, you only have to write code once in JavaScript and use this code on both iOS and Android platforms. This performance-driven framework is highly flexible and robust, making it an ideal choice for cross-platform.

    The NineHertz is a well-known technology company providing quality-assured mobile and web-based solutions at affordable prices. We have a separate team of experienced developers working exclusively in the cross-platform app development domain. We also provide you with post-sales support for timely software updates and maintenance.

    You will receive all kinds of technical and professional support from our team throughout the app development lifecycle and beyond. We will provide you with a team of at least 5 members or more, depending on your project’s requirements. Here is the breakdown:

    • One of them is a Business Analyst who does the requirement analysis, and budget prediction and discusses various other technical aspects of your project to frame a strategic business plan for you.
    • The project manager will be managing your project and he will be given the responsibility to monitor the development process and ensure the deliverables are as per the client’s requirements.
    • Then we have developers, one is a front developer handling the complete front-end part and the other is a back-end developer handling the back-end part. We may also allow you more developers if there is a need.
    • Once the development process is done, the Quality Analyst checks the output is as same as it was promised. Lastly, the Server administrator deploys the final product to the server and makes sure it runs well.

    Benefits:

    • Wider Audience Reach
    • Pocket-friendly Development
    • Faster time to market
    • Easy Maintenance
    • Code and components Reusability
    • Easier deployment and updates

    Risks:

    • Limited Access to native features
    • Performance Issues
    • Increased complexity in testing
    • User Experience Trade-offs
