Mandatory for polar scopes

I dont even know how I would align my polar scope without this app. The phone and watch combo are absolutely required. Please keep up the great work and improvements.

Polar Scope Align Pro Watch

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

Awesome

Love this app. It is a great reference tool.

Great app

Still the best!

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.
