To use this app, you point the iPhone at the sun. Then the compass will be correct. It's that easy!The developer should probably add some text to the main display, saying "Point iPhone at the sun" since some people don't seem to get that.I'm deducting one star for the unnecessary website buttons.

Reviews of earlier versions made me hesitant, but there are so few compass options for my gen1 iPad that I gave it a shot. It works well with no problems at all. I like its simplicity (I don't need bells and whistles) and the fact that you can use it as a sun compass or a magnetic compass. Too bad that iPod Touches do not have a magnetometer, or I'd load this app on my old Touch, too.If you're like me and you want to maximize the utility of older devices rather than chucking them, this app is especially welcome. I thank the developer for maintaining compatibility with iOS 5.1.1.

This app is usefull on Apple "I" devices without gps. If you know astronomy very well, this app won't help you much. But for the rest of us, it helps!I want to use it to learn how the sun moves through the sky during the year.Find a nearby place with free wifi. Have location services turned on. The location of most wifi hotspots is known. Apple uses it to find a lost iPod touch!Once the app knows your location, it can give you accurate directions!You can go hiking ten miles from the wifi hotspot and still get accurate directions from the device. Please remember the polynesions sailed the pacific ocean just by watching the sun and stars!

This is basically a "sun compass" and it does what is promises...shows you where true north is when the sun is shining. As a photographer I use it frequently to estimate when good lighting conditions might be present for other times of the day. The iPod Touch doesn't have a built-in magnetic compass so this is the best and only app that gives you an indication of direction.
