Undulib is an iPhone app developed by Charles Butler that caters to the needs of audiodrama enthusiasts. This free app falls under the category of Education & Reference, specifically in the Books subcategory.

Undulib allows users to keep their audiobooks separate from their audio drama collection effortlessly. By simply adding the hashtag #audiodrama to the comments in iTunes, users can easily organize and manage their collection. The app supports embedded chapters and multi-track books, providing a seamless listening experience.

One of the standout features of Undulib is its two progress indicators. Users can track both the total length of the audiobook and the length of each chapter, allowing for easy navigation and control. Moreover, the app remembers the playback position, ensuring that users can easily pick up where they left off.

Undulib also includes a sleep timer, perfect for those who enjoy falling asleep to their favorite audiobooks. The app integrates with iTunes, utilizing sort metadata such as "Sort Title" to enhance the user experience.

In addition to supporting Audible and iTunes books with DRM, Undulib works seamlessly with external headset or car stereo controls, providing convenience and ease of use. Whether you're an audiodrama enthusiast or simply looking for a top-notch audiobook player, Undulib is an excellent choice.
