I've been using MultiTimer Pro for years but it's never going to be for OSX so now it is less than desirable. TimeCache is simple to use like MultiTimer without all the bells and whistles of other programs. I don't need program for invoicing. QuickBooks does that. I just need a program that monitors my time and if I forget to turn it off, it stops itself. The launch feature of the program is particularly nice too and a great bonus. Cindy
