iOS E-Reader Apps

All below:

• OPDS browser with multi-download support
• Reader w/ Bookmarks, Search, Annotations/Highlights

Yomu

• Library
  • Manual archive, tags; auto-collections via file format or author
  • No Series support, no tag sync when importing from OPDS
• Reader
  • Bottom progress bar breaks up progress per chapter, emphasizes current chapter, shows rough progress through chapter
  • Justified text + auto-hyphenation + small margins make for a pleasant read.

MapleRead

• OPDS Browser
• Library
  • Manual “Sets” for books (maybe useful for keeping tech books and novels separate?)
  • OPDS import includes Series and Tag info for filtering
  • Allows sorting by series, and when in “Author” or “Series” sorts indicates the series number
• Reader
  • Very busy header bar
  • Very fine font size adjustment (with amazing pinch-to-zoom to set it)
  • Vocab
  • Anchor (mark current place for easy return if back-referencing)

Marvin

• OPDS Browser
• Library
  • Imports with series, tags, but frustratingly not number-in-series
• Reader
  • Awkward settings overlays
  • Deep View (The latter does text analysis for frequent proper nouns, I think by capitalization, which is an amazing quick reference back to when characters are introduced)
  • Image Viewer (pan/zoom on a dedicated view)
