Azimuth incorrect? – Sun Surveyor Lite Review

I may be reading the information incorrectly, but the azimuth calculated appears to be incorrect. I input a given date and time in the app and also in the US Naval Observatory website and the NOAA website. The elevations agree but the azimuth on the app is different from the ones calculated on the two websites. The rest of the app works great! Please provide a fix.
