Worth it

Fortiiiii on

This is a perfect tool. The Pro upgrade is a good deal and well worth it.

Best out there right now

Developer fixes bugs and this app is actively supported. The best I can say is very simple: It works as advertised! I sail extensively and use this app regularly. Sailingwithgrace.com

Good app, responsive developer

I'm updating my review again! This is a solid app that I've found very useful for learning about celestial navigation. I previously found a couple of bugs in the app and reported them. The developer addressed then immediately, which is really great to see. I recommend this app for its general usefulness as well as the responsiveness of the developer.

Not working

Larsche on

I paid for the seven day trial. The app seemed to work on the first day when taking sun and moon shots, but the Hc calculations did not seem to include either pub. 229 or pub. 249 corrections, the LOPs were not drawn and old LOPs could not be deleted. When testing with Arcturus on the second day the Body selector could not be be changed to a star and the app kept crashing. This may have been caused by the Star Info page being empty. Even after rebooting my iPad, I could no longer select any Body. There seems to be no manual whatsoever to be found for this app.

Nice features and accuracy!

Sweet app! Best one I have seeing for accuracy and lots of additional features 🤓. Developer gets back to questions pretty quick too.

Incredible App

This program does all the complex calculations necessary to determine your position based on your own measurements. Its fun to do the old fashioned way, but is very nice to have a precision calculator like this when you need it. Highly recommend!

Very accurate

The best one out there and so much of it is free! Amazing tool that works perfect for my sight reductions. Highly accurate and spot on with text books and for class room work. I use it for marine navigation and hope to see speed corrections included as well.
