Amazon's Kindle Unlimited is a program that allows users to access over 800,000 books and audiobooks on any device. To use Kindle Unlimited, a customer begins a free 30-day trial and then pays $9.99 per month for every month after the first.
Kindle Unlimited provides users with access to thousands of books, many of which use the Whispersync for Voice feature, which lets users switch from reading to listening to a voice narrate the book. Users can listen via headphones or through the device's built-in speakers. The Kindle Unlimited program is available as a pre-paid gift through Amazon.com. Amazon sends a gift email to the intended recipient within 15 minutes of the purchase.
Users do not need to own a Kindle to receive the benefits of the program. Kindle Unlimited is accessible on any smartphone, tablet, e-reader or laptop device. To access the program's benefits on a device other than a Kindle, users must download the free Kindle reading app and sign up for the Kindle Unlimited program. However, users must have an account through Amazon to use Kindle Unlimited. Users can manage their accounts on the Amazon home page and cancel their subscriptions to Kindle Unlimited at any time.
