Celestial Navigation Reviews

Bug with iPad when using star finder .

United Kingdom

Great app but the star finder displays stars for a second then goes blank on my iPad .

Inexpensive

Themos Tsikas on

United Kingdom

This is the first CelNav non-free app I have tried. Seems good value for money, I reproduced some sightings from 2018 with success. Be careful with the Index error: to add to the Sextant Altitude a positive quantity you must enter a negative quantity for Index Error!

Good for teaching yourself

This app is fantastic if you’re trying to teach yourself celestial navigation with no help. It allows you to check your working and see where you have made mistakes if you’re trying to get good at using tables or a calculator. You can use it to make up sights for you to reduce when you can’t see any celestial bodies, or to practice reducing sights in different locations. The only problem I’ve found is if you convert E longitude into W longitude (>180°W) it crashes the app if you try to use the map function.
