I friend of mine has just released a nice diary app with secure password. http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=294546190 It was developed for our need to have a simple app that we could securely record journal items with a date/time stamp for what we are doing during the day (to help me do my time sheet at the end of the week) I wanted something simple and quick and I think he's achieved that! As a side effect it makes a nice secret diary app It's a nice and clean simple app at the moment, but he's got lots of ideas for further development.
