I came across this handy tool Evernote recently that can aid in my content marketing efforts for my clients and myself. This is an app that can keep all my content (notes, pictures, videos, etc.) in one place that I can use to post to my blogs, youtube channel, facebook and other social media channels. Another cool thing about this app is that it can sync across devices. So, pictures you snap or videos you shoot on your iphone or andorid, and content that you wrote on your desktop can all sync to one Evernote account that you share across all these devices.
Check it out and see if it makes sense to use in your daily activities. There is a Free version and a Paid version. Checkout all the features available in Free version first.
