What are your favorite iPhone apps for learning?

[kaaist]

I've compiled a resource of the best iPhone apps for learning and I'd like to get everyone's feedback on the apps you regularly use for learning and self-education. I want to add any really good apps that I have not previously heard of.

Here are my 5 favourites:

1. Coursera
2. edX
3. MyStudyLife
4. Duolingo
5. Elevate

I would appreciate your feedback!
