If you think that your life is a little disorganized and chaotic, then you need an agenda that takes control. You need something like Personal Assistant.
Personal Assistant, as the name suggests, is an agenda that works as an assitant to organize and plan a little better all the tasks and events you have each day. It will remind you of birthdays, anniversaries, and important days.
Personal Assistant lets you create pending task lists for each hour and associate an alarm to each one, so it will tell you when the moment arrives. Also, from Personal Assistant you can establish determined priorities in the tasks, so some come before others.
All the information saved in Personal Assistant is perfectly encrypted and protected, so only you, or those with the password, can access it.
