Frequently asked questions
If you want to pick the best possible app development platform for your app, you should take into account many factors. For example: Your app’s goals, target audience, required functionality operating systems, etc. Choose the development approach: native development, hybrid development, or cross-platform development. Think about the third-party integrations needed for your app. Gather your requirements regarding the security level of your app. Evaluate the available budget. If you feel like you don’t possess enough tech expertise, we recommend addressing this question with your development team to get more objective and reasonable recommendations.
The difference between these two approaches is as follows: Cross-platform app development means the creation of a single codebase, upon which your application can be adapted for multiple platforms. It provides the ability to reuse code, accelerating your development process and making it more cost-effective. The user experience (UX) of these apps is very close to native apps, and the performance is robust. Hybrid development involves building web apps based on different web technologies like HTML, CSS, and JavaScript, and then placing them in a native container for distribution as a mobile app. It also ensures code reusability, but the performance is slower. On the other hand, hybrid development involves offline functionality. Which one to choose? It depends on your project specifics.
Data encryption, multi-factor authentication, biometrics, input validation, compliance with data protection regulations like GDPR and HIPAA, and the use of secure APIs – are just a few examples of how you can enhance your app’s security and protect it from data breaches and other vulnerabilities. With extensive experience in the market since 2017, we’ve successfully delivered a multitude of mobile apps. This experience has provided us with valuable insights into potential security challenges you might encounter, and we’re prepared to offer practical solutions to strengthen your app’s security. Moreover, we apply the latest advancements in mobile app development technologies, allowing us to provide you with top-notch security measures.
