Learning a foreign language on your own can be difficult because it’s almost impossible to tell if you’re pronouncing words correctly. The Hello-Hello World iPad app offers language courses for 11 different languages, and it has a social aspect that can help you learn better and faster. You can connect with friends who speak the language you’re trying to learn, and they can listen to recordings of you speaking and send you recorded corrections. You can also have a Hello-Hello instructor critique your pronunciations and written work, if you like. The app is free, but in-app purchases are apparently necessary; they range from $10 to $60. Right now, a Conversational course with 30 lessons and a Basic course for vocabulary training are available. Lessons for Grammar, Verbs, and Travel are coming soon.
