Take real-time votes or straw-polls with the Youhere app
Start by clicking on the orange "More..." dropdown at the top of your class roster.
Next, configure your vote. Multiple choice (A..E) and short answer votes are possible.
Then turn the vote on (click the slider). Your participants tap "vote" in the app.
You can collect short answer or multiple choice inputs from your participants.
Youhere will compile real-time results for you. You could for example, bring your laptop to class to turn on a vote, and have immediate access to the results.
In this case, it looks like A was the most popular answer, followed closely by C. Short answer results would be listed, one-by-one.
