Unlike a website, it is rather difficult to test the stability of a mobile application. With a website, we have server logs to know the errors that occur in the backend, and front-end errors are easily tested with a few browsers on a computer running Windows or MacOS. When it comes to mobile application, the process is a bit more complicated.
The testing and debugging of the API is quite easy since this data source is centralized on a server and the logs are easily accessible. It is way more complex with the application because it is installed on phones. It is not possible to fetch the logs from thousands of devices every time there is a crash, or even to know that there is a crash without having manually tested it before the deployment.
