Window listener is a simple application that observes the windows that are active on your computer and records the time spent on each window. This lets you see how much time was spent on any given task, such as writing an email, reviewing a document, or editing a picture. Please note that the application also records key presses with the intention of using this data in the future to categorize tasks. The recorded tasks can be merged in case multiple windows of the same process are used to accomplish something. Tasks can also be deleted. The tasks are remembered when the program is closed.
