What's New in GemReader
1.52.2
November 8, 2026
New in 1.52: • PDFs: search inside the document. Results are listed by page, and tapping one takes you to the passage. • PDFs: read aloud. It follows columns, skips headers and page numbers, highlights the spoken word and carries on to the next page by itself. • In PDFs, Bookmarks and Audio are now in the ⋮ menu, as in ebooks. • PDF images stored as JPEG 2000, common in comics, no longer appear blank, and the dark-mode setting that keeps photos in colour works again. • PDF highlights that cross a line break save their text with the words apart, and long-pressing a PDF no longer paints striped bands past the end of the line. • Gem Beam resumes after a dropped connection, waits longer for the other phone, and explains failures in your language. • Turning back to a chapter returns to where you left it, and slightly diagonal scrolling no longer turns the chapter. • Changing a radio answer in a form no longer brings the old answer back. • Paragraph focus keeps coloured text readable, and Serif and Sans text in gem notes and popups draws in the right font. • Permission prompts appear in your language, and you can rate GemReader from About. • GemReader now requires iOS 18 or later.
