This is a great app. It makes astronavigation accessible to any one who wants to give it a try. You can even begin without a sextant. The corrections and calculations are handled behind the screen leaving a simple user interface. Put in the information on the form and it does the rest. Particularly. Handy is the "NOW" button to accurately grab the sight time. The app allows access to all the data allowing a deeper understanding when and if you are ready. I recommend this for both real navigation and as a great learning tool
Great tool if you want to use a sextant We use this app in teaching yachtmaster ocean course. It is very easy and accurate. It fills a gap between using the sextant accurately and position fix. It does the maths for you.
OK for the price Runs fine on my Acer A500 tablet. Used daily on voyage from Australia to China. Would be great if app had Lat / Long input from my tablets built in GPS.
Very useful app! I have tested it at sea for 2 months and I am very impressed!
Very nice Been eyeing this app for a long long time. (years!) One feature request: Ability to copy- most likely location lat+long to the clipboard. Ex: DD:MM:SS.SSS DD:MM:SS.SSS My thinking is its easier use when entering location into another app I like to use (fakegps) or some other offline map apps out there (my fav mapson). Very nice app! I very much like the included star map and help file.
Handy and fun. Nice to know if gps goes out. The satilites that is. Could happen in areas. Went to private nav school, and us coast guard school for 2 years . Also learned Space navigation as startreck. We used slide rules and many tables in many books..and all our fingers and toes to do the math. This course is fun.,easy,and how to do it without lots of books.and with them. SLIDE RULE NOT NEEDED.
Add limb input to artificial horizon for better moon altitude calculation.
