(Abstract only) The AAVSO Photometric All-Sky Survey (APASS) was designed to provide precise calibrated photometry in Johnson B and V and Sloan g', r', and i' passbands for stars over all the sky within the magnitude range from 7 to 17. Data Release 10 of APASS represents an improved and full re-reduction of all of the data collected since the survey started in 2009. We provide an overview of the project aims, methods, and instrumentation. We look at some of the ways APASS is already being fruitfully used by both the variable star and the broader astronomical communities.
