Do not buy - very weak functionality – iOptron Polar Scope Review

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.
