Mac: Taking regular breaks is crucial not only to your well-being but also to your output. There are plenty of apps out there to remind you to get up from your computer every now and then, but Aware is a little different in that it simply tells you how long you've been working. The free Mac app tracks how long you've been using your computer in hours and minutes. It sits in your menu bar and shows up as a small icon, like your battery life, so you can simply glance up and see how long it's been. Via the website:
Aware tells you how long you've been using your computer in hours and minutes. It knows this because it detects the movements of your mouse and the keystrokes on your keyboard. After a short time of inactivity (a break), Aware will pause the timer, then reset and start again when more activity is detected. There are no assumptions made as to what you do with this information. No popups or alarms to tell you to take a break, just a record of time tracked in your menubar for easy access.
The app is similar to the previously mentioned Awareness. It doesn't send you any timed reminders, though, and it's free.
The app is useful if you don't work well with alerts or if you're simply curious how long you've been neglecting your breaks. Of course, you could just time yourself, but this does it automatically and makes it a lot simpler to keep track. Check the app out for yourself at the link below.
