I tried 3 others before finding this one. This one is great.

My PDF needs are pretty simple. I get documents here and there and I need to either fill out forms, or sign my name and add a date. You would think that the other PDF applications on the App Store would all be able to handle that simple task. Amazingly, no. Fortunately this one works like a charm. The interface is simple. It lets you add your signature via an already saved image file, or you can actually use your mouse to scrawl one in there if you so choose. (Pasting an image is probably the more professional way to go… but to each his own. The mouse drawing method actually does work pretty well as theres a separate window for writing it). The text entry is very clean and straightforward, and allows you to edit the text, change the fonts and colors and tweak the position it after youve entered it). This is a well thought-out, simple and well executed app. The price is nice and low, and it does exactly what I need it to do.

Obiofulious about Sign PDF
