Would you believe that you can influence your spectator's selections, through a pre-recorded video, while the video is playing? YES, with the Duality app you can. A selected number (or name, country, etc.) visually appears in a playing video. After the effect is over, the app immediately gives you the option to share the video clip (not a link but the actual video) with your spectator through your favorite social media platform, carrying the magician's contact details such as FB page or Instagram or website. Duality will get you new gigs. Yes, it's that simple. You speak to your spectator through a video and ask them (while the video is playing) to select a random number (or a word, name of a country, etc.) The spectator's secret selection appears in that pre-recorded video. Booooom!!! The application is ready to perform at any time. All you need is your mobile phone. It is very easy to perform. The one-time set-up (per video) takes only a few minutes. As you finish the performance, you can immediately share the video with your spectator through any social media platform! Let Duality grow your networking!
