Overview
MapleRead is an advanced versatile ebook reader app with plenty of useful customization options.
There are 3 editions, namely SE, CE and CX, where SE is the most feature-rich edition.
- SE: EPUB & PDF reader + book server
- CE: EPUB reader
- CX: Limited edition of CE, mainly for demo
SE and CE can run side-by-side via split view multitasking.
If you are not sure which edition you'll need, then we definitely recommend SE. Moreover, if you want to read two books side-by-side on iPad, then we recommend purchasing SE and CE as a bundle priced at a deep discount.
