StrawberryCat PDF Presenter allows you to pitch a presentation in PDF format from your iPad.
You can connect your iPad to the display with an Apple AV connector cable or over WiFi to an AppleTV.
The iPad display shows the current projected slide, the next slide and the previous slide. Tap on the next or previous slides to move forwards or backwards.
A slider at the bottom of the screen show where you are and allows you to move non-sequentially through your presentation.
Import presentations from Mail attachments, download them from Dropbox, or use iTunes file sharing.
To control presentations from your Pebble watch, you must install the companion app on your watch. The companion app is available from the StrawberryCat website: http://www.strawberrycat.com/pebble-app-for-pdf-presenter/
