## What is Polar Scope Align Pro Watch?

Polar Scope Align Pro is a complete toolkit for amateur astronomers: accurate polar alignment, deep-sky observing, astro weather, push-to/manual GoTo, iOptron mount WiFi control, widgets and more.

### 5/5 — Polar Scope Align Pro Watch

*2025-08-30*

Best in class by a wide margin. I can’t think of anything to improve on it for the current updated version.

### 5/5 — Awesome

*2024-08-22*

Love this app. It is a great reference tool.

### 5/5 — Rate app

*2024-08-11*

Great app

### 5/5 — Still the best!

*2024-02-18*

This app does it all. I’ve downloaded other apps to do things that I later realised could be done with this app alone. Take a LONG time to go through all of its features and you won’t be disappointed.

### 5/5 — Awesome

*2023-06-19*

Love this app. It is a great reference tool.

### 5/5 — Unverzichtbar.

*2023-03-10, version 6.3*

Einfach Klasse. Einnorden leichtgemacht und Sichtbedingungen aus mehreren Quellen in der App abrufbar. Für Himmelsfotografen definitiv ein Muss!

### 5/5 — Geniales Tool

*2022-11-14*

Dieses Tool löst so viele Probleme! Einfach genial! Durch die Möglichkeiten zum Polar Alignment ohne Sicht auf den Polarstern kann ich nun auch vom Balkon aus fotografieren. Danke!!!

### 5/5 — All I want to do was find Polaris …

*2022-09-03, version 6.2*

Lol. This app is chock full of things I can’t comprehend…yet. It is much more than a utility but it’s also a teaching/learning tool as well. I only poked around for a few minutes and was overwhelmed with all the details. Fortunately, this app has a great help approach which is why I’m writing this review.  Even though you might not know the things this app displays/configures/mentions, you will be guided so that even a novice at astrophotography/space like me will be able to find their way around. Most apps do a poor job of guiding you but this app does an excellent job. 

Great app so far. I’m looking forward to seeing what this app can do and also to polar align my star tracker even though my view to Polaris is obstructed which is why I purchased this in the first place.

### 5/5 — Ravensnne2009

*2021-12-16*

Wonderful so useful

### 5/5 — My GOTO App

*2021-09-09*

I’ve been using this app for about a year now and it has become indispensable in aligning my scope when I bring it out for photo sessions. I have arranged my scope so that my phone will rest on it, aligned with the optical axis. I then use the Daytime/No Polarscope Alignment feature to line up on the North Celestial Pole. I do my final polar alignment when it gets dark using the alignment feature in scope control software (EKOS) and Polar Scope Align Pro has gotten me so close already it has saved me quite a bit of time each evening.

The leveling feature of the app has been much more accurate than the bubble balance built into my mount as well. I know I haven’t scratched the surface yet but these features alone make it well worth the small investment.
