Comments on Sight reduction for Android

★★★★★ Very nice. Ideal for saving time plotting a fix or simply checking your work. Recommend using the developer's almanac app alongside this one. Thanks!

★★★★★ Great app, but I have two points to mention. 1) When I twist the smartphone (Samsung S-7) to horizontal all the previous LOPs disappear. So I have to re-enter all that data. Argh! 2) It's seemingly impossible to enter a negative IC (instrument correction). The work-around I use is to enter a negative value in some other APP and then copy/paste into the IC correction space. In conjunction with the Nautical Almanac app that I have this is a near perfect combination. I'm not giving up my GPS units, but it sure is nice to have some old-school stuff around as a back-up.

★★★★★ Great!!! Save a lot of time and a lot effort for a bunch of paper works required now a days on a merchant shipping... Thanks.

★★☆☆☆ Time would be important! Looks great on the surface.... No place to enter the time of the sight. Really Lame. DON'T BOTHER

★★☆☆☆ Piece of garbage Piece of junk. Does not work on Galaxy 6 or 7

★★☆☆☆ 2 things are wrong with this app! it doesnt calculates apparent altitude correction and the interpolation value for refraction is also wrong! fix it please..
