Need to provide a brief on how to use the data displayed to find Polaris quickly other wise it’s just data

Works flawlessly.

Four iOS devices give 4 different readings with a variance of 35 degrees

This is my go to app when setting up. Works great!

Don't waste your money. Bought it hoping to find an obstructed polaris it needs unfortunately to see it. BTW not intuitive and I work in software. If you already know how to align your scope this sw is useless, USELESS!

Astro Locator is quite the compass and does exactly what it is designed to do. I use it to align my telescope to true North and also set the declination more accurately than the gauges on the scope. One caveat is that, through no real fault of the program, it is really sensitive to any magnetic source. This results in false readings if not adjusted for. I have to move my 12 volt battery pack at least 75 feet away to get an accurate reading. That said, I still like the program and find it useful.
