CryptoCab is a virtual filing cabinet for your iPhone allowing you to always have all your information at your finger tips.

Notes can be plain text or encrypted text and are organized in folders.

I wrote CryptoCab to serve as my auxiliary brain, and have been using it for over two years now to store such things as: important information (bank accounts, details of web accounts, data about car, etcetera), recipes, to do lists, and all sorts of data I like to have with me at all times.
