I use wunderlist (now acquired

by MSFT) to create packing lists for my trips and am now storing screenshots or articles that I may need on my leisure trips in evernote. I use instagram to post my images. I used to be a big flickr user, but I hate the mobile interface.
I sometimes use day one to create small trip journals - although I still like paper journals.
Everything gets backed up to the cloud - either in carousel(RIP)/Dropbox or evernote.
What other cloud apps do you recommend I check out for travel.
thanks.
