Audible is a U.S. online service distributing audiobooks and podcasts. Users can buy or stream spoken word content either individually or via a subscription. The subscription provides monthly "credits" for content and access to an on-demand library. A free audiobook is offered to new users, which they keep after the trial period. The 30-day trial is free. The Audible app, compatible with Windows devices, allows library access on the go. The service includes the Plus Catalog, featuring a wide selection of originals, audiobooks, and podcasts, available for streaming or downloading without credits. Offline listening is supported, and content can be enjoyed with or without WiFi. Audible also offers seamless switching with WhisperSync, allowing users to read on Kindle or listen on Audible. Other features include a sleep timer, a kids profile, and various discounted membership options. The Premium Plus membership provides access to the entire Plus Catalog, a monthly credit for a permanent title, and an extended selection of bestsellers, originals, and new releases. Titles bought with credits stay in the user's library even if the subscription is cancelled.
