Do Fictionaries work on _____?
Fictionaries currently work on e-ink Kindle devices,Kindle iOS apps (iPad/iPhone), and any software that can use the StarDict format such as the FBReader and Moon+ Reader Android Apps (requires ColorDict). Amazon has not made it possible to change to a custom dictionary within the Android Kindle app, Kindle Fire or Kindle for PC. I believe this capability will be added in the future. Other e-reader such as the Nook do not allow easy switching to custom dictionaries either and store the dictionaries in a database format instead of an easier to create ebook format.
