It’s free! (Mobile device not included)
The publisher of Poetry magazine, The Poetry Foundation, has put together and put out the POETRY app for Android and iPad. (It was available for iPhone in May 2010.) It’s updated regularly with new poets and poems for its subscribers. As best we can tell, it’s a more technologically trendy take on the Poem-of-the-Day emails one can receive from various sources, such as the Academy of American Poets, although subscribers can also read the three most recent issues of Poetry, change text size, and enjoy other nifty features.
