Surprisingly useful, Readdle's free Shakespeare app for iPhone, iPod, and iPad includes the complete works--that's 41 plays, 154 sonnets, and 6 poems (even doubtful works). Perfect, on-the-go information for teachers or fans! I've even whipped out my iPhone in class, when I couldn't remember a detail about King Lear or Hamlet. How many lines are in Antony & Cleopatra? 3573. Which came first, Two Gentlemen of Verona, or Titus Andronicus? Two Gentlemen, 1592. Of course, you can upgrade to the Pro Edition for $9.99 if you like, but I haven't found it necessary yet (and I teach Shakespeare), as there are a ton of free goodies besides the works: a search feature, scene-by-scene breakdown, glossary, quotes, bio, chronology, and more. There's even a section on Elizabethan Theater. Version 3.2.2 is available, with optimization for iOS 5, and it's gotten great reviews. In fact, I've never had a loading problem or bug. You can download it for free at iTunes, at the link below. Enjoy!
