Unusable since unreadable

I wasted money on this app. Its just a miniaturized PDF which is completely unreadable on an iPhone.

Whoever wrote they live it and its easier than carrying a book, carry a microdot version is even lighter.

The app would be usable if the text resized into columns. If you zoom in then youll be sliding the screen text image left right to be able to read it and up & down.

Looks lovely as a miniature book, A waste of money in usability.
