OneNote is probably the least used Office app, although one of the most useful, if not the most useful because it allows you to store all your ideas in one single location, in almost any conceivable format. First of all, OneNote is free of charge (yes, you read it well, zero, nada, nil). Second, OneNote is available on almost all platforms: Windows, Mac, iPad, iPhone, Android tablets and Phone. To set it up, go to www.onenote.com and download the right version for you, or go to the Store (Windows, Google Play, App Store) and look for OneNote. Set up OneNote on all your devices to really get the full power of the platform.
One account to rule them all
A Microsoft account will be necessary to get the full power of OneNote. Any email address can become a Microsoft account (yes, even a gmail or a yahoo account). Once created, ensure you are identified by OneNote with this Microsoft account.
The File Menu, Account option will allow you to change account or sign out. Note this account is used by all the other Office apps as well.
Note your idea down and let it sync
Once you linked your Microsoft account to all your OneNote apps, your OneNote Notebooks will now synchronize automatically. This means that if you take a note on your iPhone, it will appear automatically a few seconds later on your PC, because of the magical power of the Internet, like below between my laptop and my phone.
This synchronization works in all direction and if you come to setup a new device, it will sync on this new device too. OneNote is much more than a note taker, as it allows as well to store picture, grab web pages, create lists, draw with your fingers or your pen (on your touch screen), and collaborate with other people over the same notebook!
With OneNote, you’ll never loose anything and will gather in one single locations all the information you need for any of your projects!
