WorkFlowy is a browser extension for Google Chrome browser that provides you with a quick and simple way to take notes or create to-do lists. You can install this application from the Chrome Web Store and read the reviews written by other users on the product's page.
When you install the Google Chrome browser on your Mac and then add an extension to the program, a new app is activated in your Applications folder - Chrome App Launcher (displays a list of all installed browser extensions). So, in order to find and launch WorkFlowy on your computer, you need to go to Chrome App Launcher and not the browser.
WorkFlowy gives you access to a comprehensive video tutorial, a list of various commands, and direct access to its support team. The application is very simple to handle, lets you create as many to-do lists as you like, and automatically saves your notes.
Another advantage is the fact that it syncs all entered notes with your WorkFlowy account. This account is created before using the application on your Mac.
My only issue with this program is that it's available only for Google Chrome browser. I work with Mozilla Firefox on a daily basis, so I had to install Google Chrome on my Mac in order to have access to WorkFlowy.
However, it's definitely worth trying this free application on your Mac if the aforementioned flaw doesn't mean much to you.
