Rdex is a free form, cardfile database designed for easy data storage and retrieval. Use it to store addresses, phone numbers, online logins, recipes, or anything you might need to find again. Searching is simple, just type a word into the search box to find every card containing that word. Designed for simplicity, Rdex requires no dialogs, no fancy fonts, no typing into multiple fields, just copy-and-paste or type into a new card and you are done. Versions of Rdex are available for Java and as an app for Android. An encrypted file format is now supported by all versions of Rdex.
