Otherwise happy with app. ,

Interesting but needs work.

Not intuitive, star map jumps when trying to take sight, star names don’t register correctly upon taking sight.

2022malo ,


I have using to practice celestial navigation problems ,its work very good Also using the artificial horizon in my back yard I can see the LOP in seconds and it help me to refine my skill with the sextant
I would like to use GMT hrs instead of Local Time in the calculations In the PC you have the option but not in the App
I like the Star finding

Worked great till IOS9

The app was great and worked beautifully till IOS9. So far it just quits right away as soon as the app is started. I hope it is fixed soon with an update.
