Description
iMariner Celestial Navigation is a complete toolbox : sight, fix, meridian, starfinder, solar compass Also embedded : nautical almanac (sun, moon, planets, starts) and astronomical computation (no more need for HO-249/HO-229 tables) - displays almanac informations : Sun, Moon, Venus, Mars, Jupiter, Saturn and 92 brightest stars. At this step, you can use these almanac data with HO.249 tables, if you want to reduce manually. - reduces a sight : getting your observed altitude and the precise time, it calculate Intercept and Azimut. You don't need any calculation ! Simply report Intercept and Azimut to your navigational chart. - You can save your observations by passages and send them by email in CSV format - take a fix : with two sights, iMariner is able to calculate your position (latitude/longitude) - meridian passage : iMariner helps you to take observations mandatory to know your position (latitude/longitude) - sight preparation : iMariner proposes you the best objects, here position (azimut and elevation), and the approximate time of the day the observation can take (nautical_twilight or nautical dawn). iMariner is a standalone application. It doesn't require internet connection. It is light and calculations are optimized to save energy on your boat. Includes a solar compass (and moon compass too).

Over priced
Somewhat lacking in features for the price. I wish for a full refund.

Excellent app, great service
I use this app every day as a professional navigator. Very good for quick azimuths. iOS update created some color problems. I emailed them, and the problems are fixed with a new version very quickly.

Cool app
I've been impressed with this app since I figured out how to use it. Really all I'm doing with it is using it as a calculator for sights I've taken and it's a labor saver. I use a drum sextant and enjoy it. This calculator makes the solution faster to arrive at. That said, I still do it longhand because electronics can, and often will fail. Of course, this is why we still use sextants and windvanes :p
