summary app, count working time

In Exembit we are developing a new application, to allow freelancers (or any worker) to count the time they dedicate to each project and also have an automatic notification in real time of the profits obtained by the hours worked. Assigning to each hour of each project the price/hour agreed with each client.
We are working on it, and it will be available from January. I'll upload the download links then. I hope you like what you're seeing.
thanks! :D
