Lucid Reader app for iPhone and iPad

A PDF viewer has been developed with a focus on just "reading" PDFs.
Convenient functions for viewing not only normal PDFs, but also documents scanned by yourself.

- Page turning by touch or swipe
- Page turning can be selected for right-binding or left-binding (pupular in Japanese) books
- The display area and magnification ratio can be set separately for left and right pages, so the display area can be maximized to minimize margins.
- Page lock prevents the display area from being shifted by accidental touch.
- Full-screen display is also supported.

To open a file, click the folder icon in the upper right corner of the list or select "Save to Lucid Reader" from the action menu of the PDF opened in another application.

In addition, a secret mode is available with in-app purchase.
The functions are as follows:
- Files can be hidden from the list by swiping right
- Hidden files can be displayed only when the top left button is pressed, preventing file names from being seen by peeking from behind
