A fantastic little Ap to have!

Being in a digital school there's lots to show and tell when we have guests come to check out what we do...and we have many guests.  So, as you can imagine, there has been many a time when 'murphy's law' comes to play with setting up and showing a presentation to guests only to find there's a glitch in the technology.
Well, this fantastic little ap should take some of that stress away...we hope!  Love the concept and the efficiency that this ap provides.
