Lifelong Learning

31. Vocabology

Quadrennial? Macaronic? Arable? Vocabology is a free app that teaches you a "word of the day," pooled from several sources on the Internet. This includes traditional dictionaries (such as Merriam-Webster), current slang dictionaries, SAT Word of the Day and words from other languages, too. The app offers a word and definition, synonyms and examples of the word being used in a sentence. There's a quiz, and an optional in-app purchase that lets you hear pronunciation of each word. (iPhone)

32. Google Sky Map

The sky's the limit for armchair astronomers: the free Google Sky Map app lets you discover and browse the night sky by simply pointing your phone to space. Learn the name and location of planets, stars and constellations by taking advantage of the phone's GPS, accelerometer and digital compass. More than a thousand stars and all of the planets in our solar system are searchable and visible in the app, but you can also view and search for constellations and individual stars. Out of this world, huh? (Android)

33. TED

Available free to iPhone users, the official TED app includes hundreds of talks from some of the world's most fascinating people — including business mavens, spirituality gurus, tech leaders and music legends. Content includes nearly 1,000 TEDTalk conference videos (with new talks added every week) and on-demand streaming audio from TEDRadio. The entire library is available for searching or browsing, in both online and offline modes, plus you can share favorite talks and playlists with your friends. (Android, iPhone)

34. Fotopedia Heritage

Recently named one of Apple's top 50 "Hall of Fame" apps, Fotopedia Heritage houses more than 30,000 beautiful, handpicked photos. Created with the UNESCO World Heritage Centre, the app also lets you virtually visit culturally significant sites around the world with interactive maps. View photos as a slideshow or wallpaper, shake your device to load new imagery and share your favorites via email, Facebook and Twitter. (iPhone)

35. Kindle

Kindle is a free e-book reading app that lets you flip through millions of digital books, magazines, newspapers and other content. Features include adjustable font sizes and brightness, instant dictionary word lookup and the ability to share quotes and passages with your friends on Facebook and Twitter. If you have an Amazon Kindle reader, the app syncs with it to remember where you left off in any of your books. (Android, BlackBerry, iPhone)
