Donna doesn't just keep track of your appointments and calendar. This software takes scheduling to a whole new level by incorporating things like traffic, parking availability, and weather delays into your travel time between meetings.

The software is designed to analyze user behavior in order to predict future needs, improving with increased use.

"The more you interact with Donna, the more she learns. You don’t need to enter exact addresses for Donna to figure out where your meeting is and she will even try to guess where you’ll be leaving from," says the company's website.
