A new app called Ovation aims to help productions both live and online figure out what their audience thinks. It requires no downloads, and no sign-ups on the user’s part and it’s totally free right now. The app is pretty simple is straight forward.
You just create a URL for your event. Then give your audience that URL, which they load on their smartphone. Audience members then use the on-screen slider to provide feedback. Either slide the bar up or down, because either it is good or bad. It works across a bunch of smartphones and mobile devices. So go ahead and tell these people what you think about their show.
