6. Consistency between different platforms

Providing consistency between multiple platforms can be challenging, given how much platforms like Android and iOS significantly differ, particularly in terms of the development experience. For example, tools and libraries aren’t the same on these operating systems, so there may be many differences when it comes to the business logic. Some technologies, like Kotlin Multiplatform Mobile, allow you to write and share the app’s business logic between Android and iOS platforms.

7. Security

Security and privacy are especially important when building a critical mobile app for business, for example, banking and e-commerce apps that include a payment system. According to OWASP Mobile Top 10, among the most critical security risks for mobile applications are insecure data storage, authentication, and authorization.

You need to ensure that the multiplatform mobile development framework of your choice provides the required level of security. One way to do this is to browse the security tickets on the framework’s issue tracker if it has one that’s publicly available.

8. Educational materials

The volume and quality of available learning resources about a framework can also help you understand how smooth your experience will be when working with it. Comprehensive official documentation, online and offline conferences, and educational courses are a good sign that you will be able to find enough essential information about a product when you need it.

Key takeaways

Without considering these factors, it’s difficult to choose the framework for cross-platform mobile development that will best meet your specific needs. Take a closer look at your future application requirements and weigh them against capabilities of various frameworks. Doing so will allow you to find the right cross-platform solution to help you deliver high-quality apps.
