Rectoly for Zotero app

Many academic papers are formatted in two columns, which means repeatedly pinching and scrolling horizontally when opened on iPad or iPhone. My library is in Zotero. However, there was a challenge: there was no screen designed for "reading."

Rectoly syncs your library to your device through Zotero account integration and opens papers in a reader designed for reading. With "Reading Mode," two-column papers flow into a single column, and you can highlight, underline, add sticky notes, and handwrite with Apple Pencil directly on top.

Main features:

• Reading Mode (two columns → one column. You can return to the original PDF anytime)
• Annotations with Apple Pencil (highlighting, underlining, sticky notes, handwriting)
• Workbench (iPad) - pin figures beside the text and read through
• Split View - display two papers side by side
• Offline viewing support (when downloaded)
• Soft Dark to darken the page itself, support for 20 languages
• Highlights, underlines, and sticky notes sync bidirectionally with Zotero. Annotations added in Zotero Desktop also appear in Rectoly
• Handwriting on PDF pages syncs as ink annotations in Zotero (also appears on the desktop side)

With the concept of "reading, not managing," the library stays on the Zotero side, and the design specializes in reading features. Zotero remains free as always, and Rectoly is a paid iPad reader that sits on top of it.
