Comments on PolarFinder Pro for Android

★★★★★ Rob Schwarze · Sep 28, 2025

Great help every time I assemble and align my telescope equipment. It displays my gps location, time details, and a helpful reticle to polar alignment correctly.

★★★★★ D. A. Ackerman · Feb 5, 2021

Polar Finder Pro quickly locks to GPS and uses time to do exactly what you expect, giving polar alignment instantly. Options to change reticle, invert view to match polar scope and insert location distinguish this app. Simply, it does what you want.

★★★★★ Zane Ross · Jun 19, 2024

Gives me my GPS location and makes polar alignment with the iOptron Sky guider Pro very simple.

★☆☆☆☆ Christopher Erickson · Jan 19, 2021

Useless app. Not useful with polar scopes from Astrophysics and several others. My review is precise and accurate.

★★☆☆☆ Oisín Dorgan · Apr 18, 2020

This was the first app I used for polar alignment. For 2 nights I couldn't get correctly polar aligned and blamed myself and my setup. 3rd night I downloaded a 2nd app to compare polaris' position with, and it was a solid 5' off even though time, date and coordinates were identical. Was able to polar align successfully with the other app. I uninstalled immediately after.

★☆☆☆☆ rowan tuuta · Jan 21, 2021

Pretty much useless in the Southern Hemisphere. Just like all polar finders. Can't change redical type etc. etc . Must only have telescopes in the Northern Hemisphere I reckon

★☆☆☆☆ Behind The Lens · Nov 24, 2021

This app was rs 460 in my country, I was charged 110 rupees more than the cost, I demand the developers to refund me the extra amoun.
