Android: Despite the internet revolution, books are still a valuable source of information. Reading takes time, though. If you're the type to stick to non-fiction, fact-filled books, Blinkist can help you get to the good parts.
The app takes a selection of non-fiction books and prepares them in sections called "blinks" that are designed to be easily digested in about 15 minutes. The blinks are curated, so an actual human picked out the good parts, rather than a computer scanning for what it thinks might be important.
