Yes, you need this Sender app as well as the Viewer app... sheesh!

This is a FIVE STAR APP (suite) for what it does. Which is QUICKLY and PAINLESSLY transfer files to be read to a few iOS devices.

You need this Mac App to SEND files (like PDFs) to the VIEWER App. Thats why this is free, and the iOS AirDoc Viewer App is currently $3.99 (universal, and does support the new iPad, yay!).

I had NO TROUBLE figuring out that you need both, without visiting the website. It was REALLY SIMPLE:

1/ Download and run Mac App.

2/ Download and run iOS App.

3/ Oooooh, theres my iPad, ready to have a file dragged onto it... Drag. Done.

Cmon folks. Cut the Indie Developer some slack. As to what I use it for? Dragging city magazine PDFs to a couple iPads (an old v1 as well as the new new v3).. the iOS app opened the 14MB pdf fine.

Fiver stars, and with the iOS viewer app on sale its a no-brainer. Go get it!
