As user's review-"No other Bible app allows you to do so much on one page" - Unlike other bible apps on the market, can only read bible, commentary or dictionary - one at a time, "Handy Bible" provides very unique feature - "floating", "Movable" and "half-transparent" bibe/commentary/Dictionary/Personal Note reading window on top of bible text, so that you can read all these texts at the same time. The only app to open up to 4 bible windows (others can only have up to 2) - each bible window can adjust its own size and assign its own bible translation text. And moreover, you can assign "Bible Parallel" to one of these 4 bible windows. These features allow to have all bible translations viewable on the same screen without flipping back and forth. Plus the above "float" commentary, dictionary, personal note and bible search popup window, you can have all kinds of bible study contents shown and viewable on the same screen.
