I have been an avid user of Evernote now for several years. What is Evernote?
Evernote is a way to collect and organize notes, ideas, web articles, handwritten notes, photos, and much more. Best of all it is cross platform – Mac OS X, iOS, Windows and Android. Evernote has a Free, as well as a Premium ($5/month) and Business ($10/month) plan. I have been using the Free plan thus far and I have been very satisfied with it.
Evernote allows you to set up Notebooks, then add notes to those notebooks. The Notes can be Notes created within Evernote, photos or clippings from web pages. I have the Evernote Web Clipper installed in Safari (it is also available for Firefox and Chrome). That gives me a button added to the Safari header which allows me to clip (anything from just the URL to the entire Web page) from web pages that I visit. This is a great way to collect information for later use. I save recipes, technical articles, and just sites that I am interested in.
I have a separate Notebook for each of the topic areas that I am writing about so that articles I find can be saved for later use. The great thing is that everything I save while I am on my Mac Mini is also available on my iPad and iPhone.
One of my Notebooks is just for Books and Reading. I have a Note there that lists all of the books that I own and that I have read. That makes it easier on the rare occasion that I go into a used book store. I can easily look up what I have and have not read by an author. I have also seen books at the brick and mortar stores that I am interested in, but want the eBook. So I just use the camera within the iOS Evernote App to take a picture of the book cover with my iPhone and save it to my Book Notebook. That way I have all the information I need for later to try and find the eBook.
All in all I find this to be one of the most essential apps whether for OS X or iOS.
I came across this article on how to use templates to make Evernote even more productive. If you use Evernote, these are good ideas.
