Socratic was launched for Android on May 2nd, but it has been on iOS under the name Homework Genius since last year. It has a pretty interesting premise: you take pictures of your homework, and it tells you about the topic and provides answers. How well does it actually work, though?
Pretty well, actually. I tried it out with some worksheets I found in a quick search and was pleasantly surprised.
