  1. 5/5Great!

    Broke out my Sextant and started playing with it again. This app makes it fun and easy to see how well you're shooting. If you use your GPS is your DR and you're not too far away or close than you know your site is accurate. This app makes it fun and easy to use again. I don't feel like I'm cheating, but I do feel like using my Sextant again.

  2. 5/5Very 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.

  3. 1/5Not working

    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.

  4. 5/5Incredible 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!

  5. 5/5Nice 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.
