Pdfremote

Pdfremote is a service for the synchronized demonstration of a presentation on any device. Upload your presentation as a PDF document to pdfremote.com with any device, share it via a QR code, and view it in sync with other participants. With Pdfremote, you don’t need a clicker; control the presentation on a projector with your smartphone. Once the demonstration is finished, the link becomes unavailable which protects your presentation from further distribution or downloading.
