Project Calculator is a very simple tool that helps you tracking the time you work on your projects. It is meant for small projects which don't need a fully featured project management system. You can manage several projects at the same time.
You can start a timer when you begin working on a project, pause timers and stop them when finished. All timer data can be edited any time.The software also features filters, reminders using Growl, tagging of timers, flat fee entries and export to different formats (such as PDF, CSV or text).
Upgrades from version 2 are available for $9.99.
