  • Agenda: For appointments, things to do, birthdays, anniversaries
  • Data: For names, addresses, or other database use
  • Jotter: For making quick notes
  • Time: For alarms
  • Calc: For simple or scientific calculations
  • World: Shows a map, world times, dialling codes
  • Word: For writing documents, letters
  • Sheet: For tables, spreadsheets, graphs
  • Program: Editor for writing computer programs
