It can be as simple or as complex as you wish it to be. You can plot your exercise program against your diary of health notes and see how they interact. Add information about changes in your diet and see how these changes have affected your health and activity levels. See how your mood is affected by your sleep. Track fatigue against dreams, diet or any part of your life that you choose. In addition to using informative graphs to show you how your choices affect your life, Smart Diary Suite has all of the functions that you would expect to find in a professionally designed Personal Information Manager.
