MangaDuo Reader
Two-page manga & comic reader
2,99 €
Read your ZIP, RAR and image-folder manga as a two-page spread the moment you open iPhone Duo. Turns like paper, even by voice. All on your device.
MangaDuo is a reader for the manga and comic files you already own, made for iPhone Duo. Read one page at a time with the phone closed; open it and the same page becomes a two-page spread. Pages turn like paper, and you can turn them with your voice.
WHY WE MADE IT
Hold a folding iPhone in landscape and you are holding the shape of an open book. Most readers treat the screen as one flat panel: the spread misses the fold, a gap opens between the pages, or a page straddles the hinge. arcion Inc. built a reader that treats the fold as the gutter of a book, first for our own use, and now as MangaDuo.
WHAT IT DOES
■ Open it, and you are already on a spread
On the outer screen you read one page at a time. Open the phone and hold it in landscape, and the same place in the book becomes a two-page spread. Right-to-left or left-to-right can be set for each book. The inner edges of the pages sit flush against the fold, and a wide illustration drawn across a spread is shown as one piece.
■ If the pairing is off, shift it by one page
A cover or a color insert can push the pages out of step. Tap “Shift Page” in the reader and the pairing in that section moves by one page. The app remembers it for each book.
■ Pages turn like paper
Hold a page with your finger and turn it slowly, or tap to turn it in one motion. Tap near the edge and the page flicks over; tap further in and it lifts and settles. On a spread, the page rises over the spine and its back shows the page underneath. Three speeds, or switch Page Curl off and pages slide.
■ Choose the paper and the shadow in the gutter
“White”, “White Paper” with a faint grain, or “Cream Paper”. “Center Shadow” in the middle of a book can be turned on or off. Margins take the page’s paper color, not a black band.
■ Turn pages with your voice
Say a word and the page turns. MangaDuo listens for words in the app’s language. In English the defaults are “next” and “back”, and you can change them to any words you like in “Voice Page Turning” settings. If your device can’t recognize the app’s language on the device, MangaDuo listens for the English words “next” and “back” instead. Recognition runs entirely on your iPhone, and no audio is stored or sent anywhere. Handy when your hands are busy.
■ Bring in the files you already have
ZIP, CBZ, RAR, CBR and folders of images. Pick them in the Files app or the share sheet and they appear in your Library. Japanese (Shift_JIS) file names are read correctly.
■ Volumes are gathered into series
Volume numbers are read from the file names and the same title is grouped as one series. When you finish a volume, the next one is a tap away. You resume where you left off.
■ Colors that follow your iPhone
Light and dark follow the iPhone’s appearance setting (“Match iPhone”). Pick from four light and five dark backgrounds and eight accent colors, and set how many columns the Library shows.
■ Also for iPhone and iPad
On a non-folding iPhone you read one page at a time, even in landscape. On iPad, landscape gives you a two-page spread.
