Celestial Navigation for Positive User Reviews

InexpensiveThis 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!.Version: 1.4

Exactly what is needed…no less, no moreThis app has everything that one needs to resolve several sights into a fix. Nothing is missing. There is no clutter of unnecessary “features”. The best app that I’ve seen for celestial navigation. The inputs are: * assumed position entered by user or taken from device's GPS chip * date and time entered by user or taken from device's GPS chip * celestial body selected by user from a list of sun, moon, planets and stars * altitude of the celestial body read from sextant entered by user (Hs) * index error, if any, entered by user The outputs are: * actual altitude of the celestial body (Ho) * calculated altitude of the celestial body body (Hc) * intercept distance and direction (towards/away) * azimuth (Zn) details of the calculation from sextant altitude to observed altitude are shown. details of calculation from assumed position longitude to LHA of body are shown. The calculated line of position can be saved to the "Records" and placed on the provided map via a single click. All calculated lines of position stored in the "Records" tab can be displayed or hidden from the map. This allows each set of sights to be viewed separately without having to delete the previous set of sights. A "Starfinder" uses the device's GPS and orientation to show each celestial body. NOTES: 1. By default, the stars are sorted by number...use "Options" -> "Settings" -> "Sort stars alphabetically" to sort by name rather than number. 2. By default, the time is set to local time rather than GMT/UTC..Version: 1.4

Good for teaching yourselfThis 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..Version: 1.3

Bug with iPad when using star finder .Great app but the star finder displays stars for a second then goes blank on my iPad ..Version: 1.4

Updates lead to 5 starsWithin a day of asking for a few minor tweaks the update came through. Excellent app just hug better. 5 stars..Version: 1.1
