Ginse.ng and Zoom
Many tutors will use Skype for their English lessons, but Skype doesn't have many tools that are important for teaching a language. Ginse.ng uses Zoom, a video chat program that allows teachers to run a class online just like a real classroom. First the teacher can teach you new language, then you will interact with your classmates to use that language.
Zoom is a small, simple, safe program that you can install and run in less than a minute on your computer, smartphone, or tablet. Over 400,000 companies trust Zoom.
