Chaos Manager was an organization and task management software that allowed users to keep track of appointments, contacts, and notes. The software included an appointment manager that displayed reminders and played audio files when an appointment or reminder deadline approached or passed. A notepad also allowed users to create various topics, apply text formatting, and detect URL links. In addition, it included a calendar where appointments and birthdays could be added, and national holidays and observances could be downloaded.

One of the most useful features was the synchronization over the Internet option, which allowed users to synchronize their data on different devices. Data could be imported and exported to and from the Pocket PC version of Chaos Manager and other applications, such as Outlook, via CSV files. In addition, the software allowed customization of the appearance through skins and the ability to minimize the application to the system tray.

Chaos Manager was a valuable tool for those who needed to keep track of their appointments and tasks and keep their personal data organized. Although it is no longer in development, as its last version dates back to January 31, 2010, it was a popular choice among those looking for a simple and efficient organizational solution.

This is a summary of Chaos Manager's most notable features:

• A notebook for taking notes and writing down information, with the option to split notes into different topics. The notebook supports text formatting and recognizes links to make them clickable.
• A calendar showing appointments, birthdays, and other events. National holidays and observances can be downloaded or created for inclusion in the calendar. A summary of that day's events will be displayed by hovering the mouse over a date.
• An appointment and reminder manager that alerts the user when an appointment or task is approaching. Appointments can be recurring, and a reminder can be set to appear before the appointment. If the user cannot attend the reminder immediately, the reminder can be postponed.
• An address and phone book with fields such as name, phone, e-mail, and birthday. Contacts can be sorted into groups, and groups can filter the list. Contact fields are customizable.
• A search function that allows you to find appointments, notes, and contacts in all fields.
• The option to protect the data with a password and encrypt it to prevent anyone from accessing it.
• A simple and easy-to-use look and feel can be customized with skins and wallpapers.
