InkBOOK offers what other e-readers cannot. Specifically, it supports all services like Kindle, Kobo, Onleihe, Tolino, Skoobe, Legimi, and Pocket on a single device. If you enjoy listening to audiobooks, you can use Storytel or Audible. The built-in lighting ensures that the light falls on the text and not in the user's face or the surrounding area. You can also adjust the color temperature to your liking. Any time of day is perfect for reading. If you like to read in daylight, you can take your inkBOOK eReader outside and read in full sunlight—everything will be perfectly visible.
