Celestial Compass app for iPhone and iPad

I love this software, because it shows sun, moon & Dipper. I classified this into regular one. But... I often saw a "Initialize" message when I touched "i" and see Information display, then back to software. It happens only once.(the first time) ( it saids, that message means to have occured an error ) *** add...( after restart my iPhone its phenomenon was disappeared.

I use it as a sanity check with other nav devices. Very quick and handy. Bubble level is clever.

I love your app. I use it not only as a compass, but in Line-of-Sight studies. I use it to get my survey instrument referenced to true north. There are a few improvements I would like to suggest. 1. I would like to have the ability to point at the moon as well. 2. Have a feet/meters option. 3. Have an option to show positive azimuth values from true north, no matter the time of day. Thanks keep up thegood work.

First let me say I really like this app. O use it to find positions of sun/moon along horizon to set up outdoor/astro photos. Please! please! please! Add a feature that allows you to advance the time to any day/hour/min in the future. This would make the app immensely more useful in predicting and planning photo shoots from a particular location that will be revisited in the future or knowing where sun/moon will rise/set even one or two hours ahead of time.

The app has pretty much finished its "work" when the compass shows up on the screen. The user is presented with a compass, along with the current position of the sun, moon, and big dipper. (These celestial bodies will show up at different positions as the day progresses.) The only active part during use is the level bubble floating in the center, a cute, if somewhat unnecessary element. To set the compass to north, the user is to rotate the entire phone until one of the three points of interest is properly aligned. For example, during the day, the user rotates the phone until the line going to the sun on the compass, if extended, would go all the way to the sun. The best way to do this is to hold the phone up and sight along it, looking directly into the sun. No, wait! Thats not a good idea at all! The best way is to lay the phone on a flat surface, then hold up a stick or stylus vertically from the center of the compass rose, casting a shadow of the stylus. Then, just rotate the phone until that shadow lines up with the line coming from the sun. No, wait, that wont work, either, because the developer failed to extend the line from the sun past the center of the rose. Oh, well, image where the sun line would be if it did extend beyond the center, then line up the shadow with that. The result is an approximation of True North, not Magnetic North. Because our modern time system sets clocks, not for the local time, but for the average time across the entire width of a time zone, the further you are from the center, the more error will be induced by this compromise. It will still be close enough for practical purposes. If you want a more straightforward method of determining the suns position, consider Sun Compass, from Vlad Lungu. It does extend the suns line behind the center of the rose, so that you can line up a shadow with ease. Sun Compass, however, while allowing use of either the sun or moon shadow, does not also display the location of the big dipper, so on a moonless night, youre fresh out of luck, making Celestial Compass a better choice for that. Decisions, decisions...

Very well done. Excellent verification device. Dead on for sunrise/sunset.

Immediately after the progrm opens, a pop up window appears, then disappears so fast you cant read what it says-appears to be a text entry box... Then the program freezes with no way to put in your personalized settings. Hope a dowloadable bug fix come out for this soon, looks like a great accessory program, if it worked.
