Education without a data plan

Quick note - Coursera lets you download course videos to your phone. Great for taking a class while offline. Or just saving data costs.

Wiki encyclopedia offline

I posted about offline wikipedia before but I forgot to post about the app I'm using currently:
wiki encyclopedia offline.

I don't think it's been updated in awhile and it won't give you a copy of everything on wikipedia but it's still pretty good.

Word Lens

Google bought Word Lens recently and made it free on the play store.

It's amazing, just in time for my visit to Germany.

It has a good deal of languages and works fast and perfectly without internet.

Offline maps in new google maps

Looks like there is a way to get offline maps in the newest versions of google maps.

Zoom to an area, then type or say “ok maps” directly into the search box. It seems it can handle a city reasonably well.
