Is there any alarm for out of range  in the dji go app

Yes, you will get warnings when the signal is weak and when the signal is lost.

The DJI GO App alerts you for many reasons.
On the main screen it has an Aircraft Status bar that will clearly tell you when your Remote Controller is no longer connected to the aircraft,
for whatever reason including out of range.

Now for out of range would you also get an audio alarm letting you know you are out of range or is it just visual because for example if you are looking at the aircraft and not the screen if you go out of range you may not see the visual alert. Thanks for your help

In the DJO Go app? No audible out of range alert.

In the Litchi app, you would get an audible alert when the app senses that it is disconnected from the craft, but there is a delay.

Thanks for the info
