momentem is a call tagging solution for BlackBerry users. Yes, it's deliberately a mis-spelling of "momentum". momentem is the name, and trademark, of the service. momentem allows BlackBerry users to tag and allocate their calls and other mobile activities to contacts, clients, projects and to flag them as billable. Ideal for people who account for their time, recover their mobile costs, or have to make sense of their mobile phone bill.
momentem is available as a downloadable app on BlackBerry App World.
