Aeon Timer

Aeon Timer is a program that comes in handy to freelancers who wish to monitor the amount of time they spend working on their projects.

This application provides you with a quick and easy solution for calculating fees and keeping an eye on how much time you work for every section from your projects.

You can monitor multiple projects, each with its own ramifications (consulting, development, bugs, etc.). The utility features a built-in timer that helps you calculate how much you work on a certain task or project and see how much you earned in the process.

Furthermore, you can export the records for any of the projects to your local directories and save them as CSV files. You can then share the information with your client to prove how much you worked on the project.

But the most important feature is the fact that the program can automatically stop the timer if there's no activity on your Mac. There's also an option to disable this feature.

As a conclusion, I'd say it's definitely worth installing this application if you require a simple and efficient tool for monitoring the time you spend working on your projects. In addition, this program comes without a price tag.
