Books — the kind made of paper — aren’t gone, but in a world increasingly saturated with screens, it’s important to understand what your options are when it comes to diving into a good book or article by way of tablet or smartphone. We’ve found that these apps and services make it easier and more convenient to read from anywhere; they help you build a library that’s intuitive, easy, cleanly organized and totally weightless.
Amazon Kindle Unlimited

Because the thought of paying for each book you read sounds entirely unappealing, there is Amazon’s Kindle Unlimited. For $9.99 per month, you’ll gain access to over 700,000 books (a quickly growing number) and thousands of audiobooks. From classics to heralded best sellers, you’ll run out of mental energy before you run out of words to ingest. For those who already spend a lot of time in Amazon’s ecosystem, it’s a natural extension, and it’s available on pretty much every digital device, from iPhones to iPads, Android devices and any modern web browser. The only major rub is that existing Amazon Prime owners don’t get free or discounted access, but for 700,000 books at your fingertips, you can work past that.
