IMPORTANT: the following instructions are only applicable for books in the EPUB format.

Google Play Books is by far the most versatile and widely-used application on Android for reading ebooks. Also of note is Kobo Books.

NOTICE: we do not provide support for ReadEra, which has erratic handling of footnotes. And while it is possible to use the Kindle Android application (via the MOBI format), it does not have pop-up functionality, making footnotes cumbersome.
