Timr is a time tracking and drive log solution for BlackBerry. Currently, the app is in an Open Beta and you can try it out for yourself for free.
With timr, you can track time and bill clients instantaneously. Time tracking is usually done after the job, and because there is always so much work, time tracking is usually left to the end of the day, or sometimes later. Timr provides instantaneous time tracking which means that you know the exact project costs minute-by-minute.
