About this app

Attention:
Unfortunately, the app keeps getting bad reviews because the compass or spirit level doesn't work. This is then because the device does not have a compass sensor or a tilt sensor. An understanding from the buyer is very rare. A refund is of course possible. So please convince yourself before buying whether your device has the following sensors.

-Compass sensor
-Tilt sensor
-GPS

The Polar-Aligner is a simple astronomical application for the northern and southern hemisphere to help you to align your mount easily. It includes basic tools for leveling your equatorial mount (spirit level) and to adjust it to north (compass).

Choose the Settings for the conpass.
-magnetic North
-manual declination for True North
-automatic declination for True North (offline calculation, no Internet needed)

You can calibrate your spirit level with a real spiritlevel and have the highest accuracy for a smartphone.

The daylight alignment is included for north and south hemisphere.

The GPS gives you the most accurate information about your location with the altitude and calculate the position of Polaris and show you graphically the Polaris position, the Hourangle, exact location ....

You get also information about Drift-Alignment. The tool helps you to get the right direction for the alignment. With the calculator, you can get the calculated result to align your mount with a small error.

There are many Polarscopes for:
IOptron
Meade
Orion
Sky Adventurer
Skywatcher
Astrophysics

Ratings and reviews

My phone says searching for location but never able to get it working. I have Samsung galaxy s25 ultra and I'm sure it has a GPS and tilt sensor. When I go to setting it says GPS off. I checked app info and made sure the location is turned on for the app while in use. Developer quickly contacted me and we were able to resolve the issue. If you are having GPS not working like I did, try disable precise location tracking and turn it back on for this app.

I've been using this app for a couple of years now. Absolutely an indispensable part of my kit. I use this to get level on the tripod, get elevation on the saddle and finally get Polaris to the right location in the polar scope on my iOptron. I consistently get less than 20 arc-sec (yes, arc-seconds) of error which is easily within reason for short focal length, long exposure astrophotography. This speeds my setup process significantly! Love this app!

All in one except for compass/GPS reliance. This app is great when used for setting up astrophotography tripod. I only have two issues. 1. The compass is just useless. 2. I wish this didnt rely only on GPS for finding latitude. Would love to have a built in inclometer. Frustrating to be at a dark sky site and no signal which makes this app a glorified level.
