Use pulldata to determine Web or Survey123 App?

[TL2]

I have some functionality that only works in Survey123. I would like to display a label if the web form is being used and hide the label if the app is being used.  Is this possible with pulldata()?

There isn't a "switch" you can look at.

But, you can use the deviceid parameter (see below) as a stand-in.

deviceid won't appear for web forms, so if(${device_id}='deviceid not found',1,0) should work for that purpose.

I could not find this in the documentation! Thanks for posting this. (saved me a bit of headache, but also, I wish that I could see deviceid, or something similar, on the web form).
