JCards is a Java application designed to store and manage data in any format that the user defines. Instead of having multiple applications/spreadsheets/databases to manage passwords, tasks, shopping lists, etc., JCards allows the user to define a database that contains the fields they want. This is accomplished via an easy to use interface that requires no understanding of SQL or any other database jargon. JCards was initially developed for PDAs, but has now branched into another version that is suitable for the modern desktop environment and includes a number of extra features.
SportsTracker is an application for recording sporting activities. It is not bound to a specific kind of sport, as categories can be created for all sport types, such as cycling, running, or tennis. The main advantages are the good overview of your exercises and the easy creation of exercise statistics for specific time ranges and sport types. Users of heart rate monitors (Polar and CicloSport) can import, display (including diagrams), and organize the recorded exercise data.
