Nichoe,
Yes, there are several of those sites which you can "Google" and they have taken the place of the clicker technology we have seen for a while - the only challenge is that EACH student must have a phone in order to text the responses. For some of our schools, this is still an issue as many students still do not hvae individual phones. You can still purchase clickers, however, so that every student can participate.
