Moon Maps for Android enables you to choose between imagery from the Clementine Mosaic or the Lunar orbiter Mosaic - although the Clementine imagery is generally better. You can pan and zoom in and out using the touchscreen. Points of interest are labeled with colour-coded text: for example, turquoise labels indicate Apollo landing sites.
You can search the database of lunar features - as you type, results are auto-suggested. Click a result to be taken to that location.
Since the imagery in Moon Maps was taken by orbiting spacecraft, the view is birds-eye only, and there is a limit to how far you can zoom in. However, the level of detail is certainly far greater than you would be able to see with a casual telescope.
One flaw of the Moon Maps Android app is that imagery becomes distorted as you go nearer to the lunar poles. I'm not sure why, but since I have seen undistorted images of the lunar poles elsewhere, I'd like to be able to see them in this app.
It would also be nice to be able to click a labelled lunar feature and go to a Wikipedia article (or some other source of information) about it. After awhile, the bleak lunar landscape becomes monotonous, so it would be nice to be able to switch things up a bit.
The developer of this app should take some inspiration from Google Maps and build in some more layers. For instance, the Apollo missions produced many ground-level photographs. It would be fantastic to use this app to look at them in locations where they were taken.
