Call Time Tracker by Momentem
For consultants or those who do work on their BlackBerries that has to be billed to client accounts, this handy app lets you keep track of your time spent on e-mail and phone calls, and assign the time to specific clients. After each call or e-mail (sent or received) you’re given the option to tag it to a specific contract, and can make notes on the event. The time you spent on the call or reading or composing the e-mail is recorded, and you can even set your billing rate for each contract or client. You can generate activity reports on your BlackBerry or be e-mailed a Microsoft Excel spreadsheet report. You can generate the spreadsheet monthly with the free version, or on demand with the more feature-rich pay edition.
