Do not buy - very weak functionality

It tells you where Polaris is located for your current time and location. But with no options or way to configure the display (other than English / Chinese). Other apps do this as well but with plenty of options for customization. It might be OK if it were free, but it is dismal at $1.99.

Yep...not good

Purchased and no instructions or troubleshooting guide. Couldn’t even figure out how to contact the developer. I can’t even give it a rating...I guess I’ll have to buy ZWO...

Not American English

The elevation is in metric not much help in the USA. If it can be converted to Chinese why not USA measurements? I’m not knocking metric but I’ve spent 60 years using feet ,miles and Fahrenheit. So only half of this app is of any use for me. It’s only good for alignment I should have paid better attention and not assumed it was for the US market. I can use it but I won’t have a clue about my elevation.

Hopeless App..

I feel ripped-off! I’m in the southern hemisphere and can’t figure out how to use the darn thing to find sigma-oct! Piece of junk!!
