You can QA your app a variety of ways with a variety of tools. You can QA your app via Wi-Fi or via a cable connection to your computer to view the output or logs from the tool being used to create the app like XCode, Android Studio, etc. One commonly used tool is Charles Proxy. Using Charles Proxy, you can enable settings within your device’s Wi-Fi network to provide logs of what analytics data can come up.
There are some caveats for testing between iOS and Android. For example, when using Charles Proxy to QA an iOS native app, you need to get a certificate installed in your device before beginning to see output from your native app.
The set-up process is different; but the same goal and methodology of analytics QA isn’t that different for your mobile apps as it is for your websites.
