Bought this hoping to find a nice program to have patients sign forms in the office. Quite simply, it does not work. On my iPad 3, I could not get it to insert signature fields reliably. On some docs it worked, on others it did not. Moreover, you cant control the size of the signature field--it took up 10% of the page, which is not idea. Rotten app.
