The Moon Book App clearly shows you when and from which direction eclipse of the moon can be viewed. The time of beginning or ending penumbral eclipse is simultaneous around the country but a place of beginning total eclipse differs from pace to place. The Moon Book will show you the phases of the moon eclipse at your place. You will be able to set up any observing place beforehand if the moon eclipse star chart is selected. When you move to a distant place for observing the moon eclipse, you will be able to know in advance a place where the Earthfs shadow starts hiding the moon. You will be able to check a start time of the moon eclipse overseas also. Tapping on the moon icon at the upper left corner of the star chart will show you thumbnail images of the phases of the moon eclipse at regular intervals. The interval of the thumbnail images can be changed.

Verdict
The clearest difference is review sentiment: Moon Book at 90% against Moon.'s 34%. Moon.'s advantage is update cadence (every 2 months vs every 6 months) and iOS requirement (7.0 vs 12.0). On price, ads, in-app purchases and monetization model there is nothing between them.
