Only tested the app with celestial calculations using the sun. UTC time should be calculated vice versa, since it is Greenwich the reference not the local time zone. Therefore actual UTC -3 must be inputted as +3 in the app to get a reasonable result (this is a concept bug). Negative sextant index correction are not possible to input. And I get consistent result errors when cross checking output with my manual calculations.

The map could use a little improvement, I understand that it's not for navigation, but I would like to view it in larger scale. Otger than that, this is a brilliant app!

Love this app. When using route correction with the Great Circle format, the heading is still in rhumb line. My mistake or am I missing something. Thank you.

I have bougth this application about 3 years ago and I enjoyed using it because its very simple to use. For whatever reason, GPS cannot connect any longer. Can you help me resolve this problem.

when i turn my phone display off, my Hs inputs are erased from the Celestial Observation page. Is this intentional? Any possibility to add Feet as a unit for height of eye? Thank you so much, i use this app every day at sea and i love it.

Very nice app I am very happy for that I will check again later on so you will improve better to be the best app for Navigator Yes is good app but still need to give more additional data such as geographical position of the bodies and so on More detail data even better More data from Almanac need to be on side as a guidance and choice of the navigator Keep it up I am satisfy with this app with reasonsble price This is the best app ever in the Google Play Store for Navigator

edit: Thank you for excellent application. 5star for your hard work sir. Good application but in average speed calculation it is good too if there an option for 24hrs format input instead of 12hrs only.

Great app, does most calculations you'll need. Just got this for calculating azimuths which it does very well. Plenty of other functions too. Definitely a time saver. Weird how there's no other reviews tho
