Only good while shooting

This app is designed to be used while actually shooting the celestial body. Have it open and record the shots right off the sextant. it is impossible to go back and enter your data after the fact, as the time of observation is tied to the internal clock of the iPod/iPad/iPhone. Another issue is that it only uses magnetic compass headings for the running fixes (no Gyro or True option), and it expects you to enter the Variation by hand (other apps provide that data). It also doesnt take Deviation into account on for that magnetic heading. All in all...Id pass on this app. There are better ones out there.
