Creating good slides are very important in order to give a good presentation. An other aspect you can't forget is to make sure that your audience can follow your presentation at any moment. Therefore it's interesting for your audience to have the opportunity to collect the slides before, during or after the presentation, and follow you on their phone or computer.
With the mobile application, Spraed, you can diffuse and collect a PowerPoint very easily, and even message to the presenter privately. The tutorial underneath will explain you how to do so.
