An annotated overview of 98 astronomy applications for smart phones and tablets has been published in the on-line journal "Astronomy Education Review." The listing includes a variety of apps for displaying and explaining the sky above you (some using the GPS function in your device); a series of astronomical clocks, calculators, and calendars; sky catalogs and observing planners; planet atlases and globes; citizens science tools and image displays; a directory of astronomy clubs in the U.S.; and even a graphic simulator for making galaxies collide. Compiled by Andrew Fraknoi (Foothill College), the list features a brief description and a direct URL for each app. It may be especially useful for everyone who got a phone or tablet for the holidays and is looking for something fun or educational to do with it.
