PolarAligner Pro Astro Tool is an astronomical application for the northern hemisphere that helps you to align your mount with ease. It includes basic tools for leveling your equatorial mount with a spirit level and adjusting it to the north with a compass. The app also features GPS, which provides accurate information about your location, altitude, and calculates the position of Polaris.

One of the standout features of this app is the inclusion of a daylight alignment (beta version), which makes it possible to align your mount during the day. The app also provides useful information about Drift-Alignment, which helps you to get the right direction for the alignment. The calculator is a handy tool that provides the calculated result to align your mount with a small error.

PolarAligner Pro Astro Tool supports many Polarscopes, including IOptron, Meade, Orion, Sky Adventurer, Skywatcher, Astrophysics, Takahashi, Bresser, Vixen, and Celestron. If you miss a scope, the developers encourage you to write to them. However, it is important to note that the app requires a compass sensor, tilt sensor, and GPS to work correctly, so please check your device before buying.
