Mobile apps are of two types - native and cross-platform. Native applications are written in the platform's native language: for Android - Java and Kotlin, for iOS - Swift and Objective-C. Cross-platform applications are written in a completely different language using additional tools (we have ReactNative), but as a result, we get two applications at once to work on both platforms.
Pros of native apps:
- High performance. Native code has direct access to the system, which reduces the likelihood of errors and response times.
- Maximum use of platform capabilities, more flexible functionality.
- Best UX. The interface is developed taking into account all the features of the platform.
- Better positioning in mobile app stores.
Pros of cross-platform applications:
- Use the same code for two platforms, without the need for re-development.
- It is cost-effective to order the development of one application, not two.
- Easy and quick launch in AppStore and Google.Play.
- Reach all possible audience.
- Same interface for both wasps.
Naturally, both approaches have disadvantages and certain specificities. With native development, either you have to pay for two applications, or you lose part of the audience. Cross-platform applications are not as flexible and have a slightly worse UX, because there are trade-offs between the two systems. In each case, the optimal solution will be different.
