Rdex—A Simple Personal Information Manager
Rdex is a freeform database. Use it to store addresses, phone numbers, birthdays, online ids, recipes, or a million other pieces of miscellaneous information. It is based on the idea of a cardfile—like a Rolodex. Just click "New Card," paste or type in some info and click save. Simple! Later, you can search for any text contained in the card and the card will be displayed. Just type the word you are searching for into the search box at the top.
Rdex is available for Windows, Java and Android. If you keep the data file on a cloud storage service such as Dropbox your data is available anywhere and you can maintain sync between mobile and desktop access. Rdex can also encrypt the data file if you wish to ensure privacy.
