Instapaper

It was plenty handy when it launched, and now that we're all carrying around phones and tablets that make for perfect reading canvases, it's downright indispensable. Instapaper (Free to signup, $5 app) is, for the uninitiated, an online service that lets you save nearly any webpage for later reading, thankfully stripping away nasty ads, formatting, and any other potential distractions, leaving you with nothing but beautiful words. And now, thanks to the latest iOS app update, you can also quickly browse through any links your friends are sharing on Twitter, Facebook, or Tumblr, transforming it from a simple reading tool to a constantly-updated source of awesome articles.
