Unfold

A viewer for your own TXT, comic and PDF files โ 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", "็ฌฌ1็ซ " or "์ 1์ฅ" 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.

Text Viewer

Long reads, in letters that suit you. Text Viewer is a reader for the text files on your phone. Change the type and the background right where you are reading. FROM THE TYPE TO THE PAGE Drag text size, letter spacing and line height and the page changes under your finger. Nine backgrounds, from sepia to midnight, for bright rooms and dark ones. LONG FILES, A SECTION AT A TIME Once a file is in your library, only the part you are reading is loaded, so long novels stay easy to page through. Very large files may take a moment the first time you bring them in. TURN PAGES, OR SCROLL Read a page at a time like a book, or keep scrolling like the web โ switch whenever you like. Your place is kept for you. YOUR LIBRARY Files you bring in stay together in your library. Bring in a newer copy with the same name and it replaces the old one, picking up where you left off. OPEN FROM ANYWHERE Send a text file from Files, your browser or a messenger with "Open in", and it opens straight away. IN YOUR OWN LANGUAGE Eleven languages, following your system or set by hand. Light and dark are drawn by the same rules, so nothing shifts when you switch. Text Viewer has no account and never uploads what you read.

Verdict
The clearest difference is in-app purchases: Text Viewer at none against Unfold's 1. Unfold's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
