FROGFISH.JP app for iPhone and iPad

This app seems like an orthodox photograph collection. However, this app has some advantage not on ebooks. For example, you can turn pages vertically not only horizontally.

You can move to next page by tap of the right edge of the page. Also you can move to previous page by tap of the left edge of the page.

When you tap the bottom of any photograph page, you can display the explain page.

Therefore you can brows this app as a photograph album by flick right or left.

And you can also brows this app as an encyclopedia or a photography guidebook by flick up.

When you tap the top of the explain page, you can return to original photograph page.

You can also those transition by flick.

In addition, you can switch the display language to Japanese, by changing the language setting of iOS.
