Memo Pad

This program allows you to create memos and notes on your iPhone. Its features are those of the standard iPhone "Notes" application plus much more, including:
Hiding and password-protecting private memos;
Searching and sorting memos;
Easier user input via the wider keyboard when in landscape mode;
Undeleting memos;
Categorizing memos;
Category colors;
Emailing memos;
Choosing your display font.
Future versions will include additional features that users of other platforms, such as the Palm OS, and other devices, like the Treo, have come to expect.

This differs from Memo Lite only in that the password is encrypted here.
