Barely functional. User interface is really rough. Looks like the very first app someone has ever built. Input fields lose values previously entered as you navigate around. Not intuitive. Also the moon phases feature gives completely wrong data for March 2021. Update 12 Aug 2021: Moon phases appear fixed. However the celestial fix DR position form now has a bug where I cannot change the Height of Eye from 20m - no matter what I input for that field it just saves 20m.

I'd like to request a refund. I compared its findings with other apps that we use onboard and it was way off.

Useful! Helpful! Star finder "Longitude; shows DDDmmm.ss". My suggestion will be " DDDmm.ss" in actual number values.

Please consider to check wind direction in your next updates.

Pls change the time format of UTC for STAR FINDER instead of Hours and Mins make it HOURS:MINUTES:SECONDS cause the azimuth shown is only on whole number. Pls include the missing decimals. This will help a lot. Thank you

App is very nice. One suggestion to add marine port distances also. Other thing is the picture displayed is not full on the display. I have to scroll up to see rest of the fields. Pls rectify this.

Dav. L. Nov 21, 2014     

it would be better if there is an option to take celestial observation by min and sec..not just hourly..for example i want to take gha of the moon by 1235H..just saying:)

One of the best apps for sailors of all breed. Just one very small issue the data in the welcome page is too small to read especially if you have the screen on dim, experienced this after the new update. This app has come a long way from its simple early days. As always looking forward to seeing new features, keep em coming ⚓

It is quite a good application. I like the almanac and tested with terrestial sailings with only 2 nm difference from nav calculator. It is a great application.Thanks guys..better if it will be included with port distances and world map layout for lat/long coordinates projection. Tested with gps feedback..almost same remarks..More innovations..
