Wear Reader is possibly the first, and even only, ebook reader for the Apple Watch. It is available from the Apple App Store. Naturally, you need an Apple Watch and iPhone to use it.
The operation is very simply; using the iPhone app load an ebook. You can work with ePub books, Microsoft Word documents, and text files including plain and HTML-formatted text. Unfortunately, at this time, PDFs are not supported.
Nicely, Wear Reader will connect to iCloud and DropBox allowing you to easily load documents from those sources. Once loaded, turn to your wrist and read along. Your Apple Watch will flash words onto the screen, much like a tiny teleprompter, allowing you to simply focus on the one spot.
If you miss a word and need to go back you can simply swipe up and down to rewind and fast forward, or tap to pause and resume.
The app features a night mode with an easier-on-the-eyes dark mode.
Wear Reader is a pretty innovative app, and is worth looking into if you have an Apple Watch and want to read on the go without staring at your phone.
