OneNote Mobile gives you instant access to your notebooks on your smartphone or tablet.
While OneNote Mobile doesn’t include all the features of OneNote 2013, it’s a great way to view and edit your notes on the go, and even share them with others. It’s also is a quick and lightweight option for using OneNote whenever you can’t bring your laptop — or you don’t want to.
Do the following:
Visit onenote.com and choose the version of OneNote for your device.
After OneNote is installed on your device, sign in with your OneDrive or Microsoft account. If you have neither, you can create one for free on the OneDrive home page.
Create a new shared notebook to use with OneNote Mobile, or use any of your existing notebooks on OneDrive to sync with your mobile device.
Note: If you want to use a notebook from your computer with OneNote Mobile, you must first move the notebook to OneDrive. See Move a shared notebook in OneNote for more information.
