A lot or a little?
Parents need to know that Duolingo: Learn Languages Free is an excellent language-learning app for middle schoolers and older kids (and grown-ups, too). Kids can choose from many languages -- including Spanish, Portuguese, Italian, German, and French -- using a fun, game-style system that's very encouraging. Email registration is required, but push notifications asking users to keep practicing are optional. Kids will appreciate the gentle, positive approach to mastering a language, and they'll want to move through the levels, gaining skills along the way. Read the developer's privacy policy for details on how your (or your kids') information is collected, used, and shared and any choices you may have in the matter, and note that privacy policies and terms of service frequently change.
