Just extremely useful

The equivalent of a pair of scissors on a Swiss Army knife. Without it your iPhone just would not be nearly as useful as it is.

Simply works

All we ever need from an app is that it works without difficulties.

Excellent application, very useful. Now I can stop carrying around printed hard copies of email attachments.
