There is a free app available for smart phones called
"Sight Calc"
It is very straight forward and will provide you an azimuth, a true azimuth, and a calculated altitude for any input of Latitude, Longitude, LHA, and declination. It does not plot lines of position nor does it have any ephemeris data.
Since it works for all latitudes and longitudes you can input either a DR location or an Assumed Position. Using it with an AP makes it an excellent way to check your work when you are learning to use traditional sight reduction tables such as H.O. 229 or H.O. 249.
Its beauty is its simplicity -- and its price!
