    FAQ on multiplatform development

    • What is cross-platform app development?

      Cross-platform application development enables you to create apps that run on various devices and operating systems (including iOS, Android, desktop, and web) using just one codebase.

      This approach streamlines – among others – mobile app development for iOS and Android, helping developers to efficiently deliver apps across both major mobile platforms without needing separate native codebases.

    • Do you provide app maintenance support or just development?

      Yes, we also provide maintenance. The app development is just the beginning. During app maintenance, our development team implements app monitoring tools for every product we create. These tools help us detect any issues, monitor the app’s statistics, and plan product enhancements.

    • What if I need to change or modify my cross-platform app after launch?

      We invite you to cooperate with us for ongoing app maintenance. This option ensures that the team is available whenever your project needs us. Time is reserved for you.

      If you do not opt for such maintenance, you can always contact us with specific needs, but our ability to help at that moment will depend on the team’s availability.

    • Will you sign an NDA with me?

      Yes, we always sign an NDA (Non-Disclosure Agreement) when a client wants it. We can do it at the very beginning, before we even discuss your Flutter project in any detail, or at any other stage of the process. It’s completely up to you.

    • Where is your cross platform development team located?

      Our team works in one office in Wroclaw, Poland, which is one of the fastest-growing tech hubs in the world. Its location enables convenient and fast access from any city in the world. Read more about us.

    • Is multi-platform app development popular?

      Multi-platform app development is gaining popularity because it offers a quicker, more cost-efficient way to create high-quality apps that work across various devices and operating systems. Moreover, there’s a noticeable uptick in developers adopting these technologies, underscoring their growing appeal. [source]

    • What are the top cross-platform app development frameworks?

      The leading cross-platform app development frameworks are Flutter, React Native, Ionic, and Kotlin Multiplatform.

    • What are the benefits of multi-platform app development?

      Multi-platform app development offers significant benefits. With just one codebase, you can launch your app on iOS, Android, desktop, and web, reducing development and maintenance costs. A smaller, specialized team can manage the process, leading to quicker market releases and a consistent UX across different devices and operating systems.

    • Top cross-platform developers – how to find them?

      In search of cross-platform developers, look for specialized companies that offer multiplatform services and make sure to:

      1. Review the company’s portfolio to learn about their approach to creating multiplatform apps, the development process, and the outcomes they have achieved.
      2. Read customer feedback to find out what they liked and what could be improved about working with the team. If there are no reviews available on your chosen cross-platform app development company’s website, you can check on Clutch to read clients’ feedback.
      3. Check their area of expertise. No company is specialized in all available frameworks, so it’s important to verify their know-how before hiring them. If you plan to develop an app using Flutter, look for a company specializing in this technology.

      Ask for a consultation. Speaking with your possible team will help confirm if it is the correct decision to fulfill your requirements.

    • What are the cost differences between native and multiplatform development?

      Multiplatform apps are more cost-effective in both development and maintenance. With a cross-platform solution, a single codebase serves multiple platforms, allowing one team to oversee the entire project efficiently. In contrast, native app development often demands additional time and resources since each step must be tailored for every targeted platform. This can also require hiring separate teams for each platform, significantly increasing the cost of launching your app compared to cross-platform development.

    • Which companies have successfully used cross-platform app development?

      Many leading companies, from start-ups to tech giants, use cross-platform app development services for their mobile solutions. Examples include Facebook, Instagram, Google Ads, myBMW, Xianyu by Alibaba, Nubank, and many more!

    • Is cross-platform development suitable for all types of apps?

      To decide whether a cross-platform solution is right for your project, it is best to evaluate it with experienced professionals who can guide you according to your project requirements and business objectives. In general, cross-platform development is beneficial for a wide range of apps targeting multiple platforms, regardless of a company’s size, industry, or stage of development.

    • How do multiplatform apps handle platform-specific UI?

      How cross-platform applications handle platform-specific features depends on the framework. For example, Flutter uses highly customizable, pre-built widgets that enable developers to adjust their properties and styles to achieve the desired look and behavior on each platform. React Native, on the other hand, lets you create UI native components for Android and iOS to suit your app’s unique needs.

    • How is performance affected in cross-platform apps compared to native apps?

      The performance of cross-platform apps can vary, depending on the specific project and the technology used. Advances in frameworks have made it possible for many cross-platform apps to perform almost as well as native apps, even for web applications. However, the choice of technology makes a difference: Flutter and Kotlin Multiplatform offer excellent efficiency, while React Native and Ionic tend to perform at a significantly lower level. In most cases, cross-platform development for iOS and Android now delivers high performance that rivals native solutions, thanks to modern frameworks and optimized coding practices.

    • What should cross-platform app development services include?

      When choosing a cross-platform development company, look for one that offers:

      • Discovery: Identifying user needs and challenges that your app must address.
      • Design: Tailoring the design of your app to meet business goals.
      • Development: Building from scratch or converting an existing native app using multiplatform frameworks such as Flutter.
      • QA testing: Identifying and fixing issues before the app launch.
      • Launch & ongoing support: Releasing and continuously improving your product.
    • How do I choose the best cross-platform app development company?

      To pick the best cross-platform development app company for your needs, look for ones with a proven track record, client testimonials, and expertise in your desired cross-platform framework. Clutch is a great site where you can find these companies and see customer reviews.

    • What should I look for in Flutter app development services?

      Ensure the Flutter app development services you’re considering include not just app development, but also design and backend services, if needed. Verify that they can develop apps for the platforms you’re targeting. A good service provider will adapt to your specific needs. Furthermore, it’s best if the development team that you work with follows an Agile approach in their digital product development. This means they’ll be more adaptable and responsive to your project’s changing needs. Also, don’t forget to inquire about their Quality Assurance.

    • What are the key steps to hire Flutter developers?

      1. Define your project needs: Identify the platforms you want to target (e.g., iOS, Android, web) and the key features of your app.
      2. Research potential candidates: Use platforms like Clutch or GoodFirms to find agencies or developers with proven expertise in cross-platform development.
      3. Evaluate their portfolio: Review previous projects to ensure they have experience with technologies like Flutter or React Native.
      4. Assess technical skills: Conduct interviews or technical evaluations to test their knowledge and problem-solving abilities.
      5. Check reviews and references: Look for client feedback to understand their work ethic, communication, and reliability.
      6. Discuss your project scope: Share your goals and ensure the developer or agency understands your business objectives.
      7. Confirm Agile approach: Make sure they follow Agile practices for flexibility and efficient project management.
      8. Finalize terms: Agree on timelines, deliverables, budget, and communication channels before starting the project.

      This step-by-step process ensures you hire the right cross-platform developers to bring your app to life successfully.
