T@imeCalc was designed to help private individuals and small companies to administrate as easy as possible working time units referring to the different collaborators and projects. Did you as a chief of a company head of a department or project ever wish to get working hour totals for certain projects (cost units) or working hour overviews of all collaborators by simply pressing a button? Or do you wish to keep the overall view of your own time which you invest simultaneously in different projects in order to work as efficiently as possible and to increase your productivity? Administrate your precious time as good as you can. Save time when making up your bills. Keep the overall view of your and your collaborators different activities with a short bookkeeping of the working time spent on the different cost units.
