Smartphone apps are constantly creating ways to make our lives easier and more efficient and offline bookmarking service Instapaper is one of the best in the game.

This useful app saves and downloads up to 500 web articles that you’d like to read but don’t have time to, strips them down to text only and saves them for you to read later on your iDevice or Kindle, even when you’re offline. It's perfect if you’re spending a lot of time in network black holes.

Instapaper is a great way to aggregate all that info you’d otherwise never get around to reading. Incredibly simple but very useful, it's a classic app.
