InerziaTimer is a simple Mac utility that helps you measure time on your computer. This program might prove to be of good use if you need to monitor the amount of time you spend working on your projects, learn when it's time for a break from work, etc.
The application features three integrated tools: Countdown, Chronograph, and Reminder. These utilities are very simple to configure, work perfectly, and don't slow down the performance of your system.
The Countdown tool comes in handy if you need to know exactly how much time you have left until you meet the deadline for a certain task. For example, it might prove to be of good use to freelancers who need to monitor their deadlines.
The built-in Reminder tool is useful if you need to remember when it's time to complete a certain assignment. You can select the preferred date and time info.
The Chronograph utility allows you to count multiple intervals of time (or time laps).
InerziaTimer lets you export the information you store in the Chronograph tool to a TXT file. This feature might prove to be of good use if you need to share the recorded details with other users.
My only issue with this application is the fact that it doesn't offer me an option to select a personal audio file as an alarm sound. You can only use the ones that are being offered by the program and that's it.
All in all, InerziaTimer is free of charge. So, if the aforementioned disadvantage doesn't mean much to you, you should definitely give this program a try.
