User Reviews and Ratings
★★★★★Perfect.
You put your sextant reading and it will give you a line of position. No need for nautical almanacs. But it does show all the variable values so you can double check your own calcs.
★★★★★Wow
This app is terrific! It is good to learn the “long way” of plotting your position but once you learn, then this app makes it so much easier and faster. All you need is your sextant and your watch and let the fun begin.
★★★☆☆Dip error
From height this calculates a positive dip.
I think that dip is always a subtraction from read on the sextant.
★★★★★Position calculation
This app is really good. Everything you need, full service. Not hard to learn.
Wish list: option for latitude longitude and time in decimal seconds. Verbose position output and confidence value.
★★☆☆☆Capable but crashes on iPad
A free app that is fully capable of calculating a line of position directly from a sight. Unfortunately after the first couple of sights the app won’t open anymore and just crashes immediately on startup.
