Description
Navigate in open waters without a GPS. The phone's camera is used to make sightings of the sun, moon, Venus, or Mars. The sighting results are plotted as lines of position with multiple sightings combined into a running fix. Your estimated position is displayed on a lat/lon grid. You can also use your sextant and take advantage of the built-in almanac and plotting tools.
What’s New
Version 1.6
Fixed bug in image delete.
Ratings and Reviews
A superb tool—thanks for the great work!
I am a long time user of celestial navigation, a licensed master, retired US Navy Captain, and a passage maker.
In this GPS-based world of electronic navigation, I have always maintained redundant backups, including paper, charts, and celestial navigation.
This app delivers shockingly good results with my iPhone 15. Thanks to this great app, I predict that I will soon lose my proficiency at taking sights with my sextant and then deriving my position with the nautical almanac, and pub number 229, because the app makes quick sun lines so easy!

Amazing backup !!
This celestial navigation app is by far one of the best ways I have found to learn how to use an actual sextant and is amazing how easy to use!!! Not to mention a great backup for all your navigation systems on your vessel if , in the event you lost your systems on your boat!! GREAT JOB!! It’s a true game changer in navigation!!
Excellent tool
Works great on my new iPad Pro 13inch M4.
