Can I use Socrait with a virtual classroom?

Yes. Set up the Socrait app on your phone as you would for an in-person class. 

When you start the virtual class, also press Start on the Socrait app. Set your phone down so that the phone mic is facing your mouth and will capture your voice. 

So long as you still call on students by name and teach something out loud, you should be able to see your classroom data in Socrait.
