DisplayNote transforms presentations for presenters and participants. Use it to present wirelessly with an iPad or Android and mirror your screen to every participant’s device. Attendees can view and capture your slides on their device and collaborate with each other in real-time.
Start a DisplayNote session and what you see on your screen is mirrored to every participant’s device. Stream from your PC or Mac to multiple iPads, Android devices, laptops and phones. If you make a change, annotate, add an image or view a background on your screen, it shows up instantly on theirs.
