What it does: Gives you mini teaching lessons about whatever you're interested in
Like having an entire university's worth of academics at your fingertips, the Khan Academy app provides access to over 10,000 videos that explain a wide swath of things you might have snoozed on in school, from history to science, math to economics and finance, and the arts and humanities. The best part, though? No homework.
What it does: Curates the best long-form journalism from around the web
It's easy to let the deluge of listicles and bite-sized news wash over you all day long, but for people who prefer to consume stories with a little more depth, Longform is here to keep you well fed. The app, which is like an RSS feed exclusively for great long-form journalism, allows you to follow individual writers and publications, and even curates a selection of "best of" lists and staff picks.
