A viewer for your own TXT, comic and PDF files — without garbled text. NO MORE GIBBERISH Older TXT files are often saved in legacy encodings such as Korean CP949 or Japanese Shift_JIS, and many apps show them as random symbols. Unfold detects the encoding and opens the file correctly. If something still looks wrong, preview the text in each encoding and pick the right one. CHAPTERS, AUTOMATICALLY Unfold finds headings like "Chapter 1", "Prologue", "第1章" or "제1장" and builds a table of contents. Long texts without headings are split into sensible parts. Your position and bookmarks are saved automatically. COMICS, COMFORTABLY ZIP, CBZ and folders of images are sorted naturally (1, 2, 10), and file names zipped on Windows are repaired. Reading direction is remembered per book; turn the phone sideways for a two-page spread; margins can be trimmed automatically. EPUB, PDF AND IMAGES TOO ADDING FILES Put files in Files > On My iPhone > Unfold, or use Share > Unfold from another app. Whole folders work. A VIEWER FOR YOUR OWN FILES Unfold opens files you already have. It has no feature for finding or downloading books or comics online. Samples included: public-domain Korean short stories and a comic we drew ourselves. PRIVACY No sign-up and no server. Your files and reading positions stay on this device. No ads or analytics. UNFOLD PRO (ONE-TIME PURCHASE, NOT A SUBSCRIPTION) Read aloud with the built-in voice, auto-scroll, three extra backgrounds, and backup/restore of your reading data. All reading features are free.

Verdict
The clearest difference is in-app purchases: 爱书猫 at none against Unfold's 1. 爱书猫 also leads on device support (4 vs 2). On price, ads and iOS requirement there is nothing between them.
