RemindOK - Simple Timer

RemindOK - Simple Timer is a Mac program that comes in handy if you want to set up alarms, countdown the time you spend working on an assignment, etc.

The utility has a straightforward interface, comes with simple-to-configure settings, and uses minimum CPU resources while running on your computer.

This application consists of four built-in utilities: a watch, a stopwatch, a timer, and an alarm tool. Each of the integrated apps come with individual settings which can easily be configured even by average computer users.

You can use the timer tool to count the amount of hours you spend working for your projects. The countdown utility is very simple to set up and keeps track of previous sessions reports. Furthermore, you can use the alarm tool whenever you need to set a reminder for a certain task. For example, you can set an alarm to remind you when it's time to call a client. The program lets you import audio files from your local directories and set them as alarm sounds.

I'm still unsure why you would need the clock app as the hour is already shown on your Menu Bar.

However, this program is very simple to use and offers you effective built-in tools. Plus, it's free of charge. So, I'd say it's worth installing it on your Mac and give it a try.
