I have to say I find your adversity to cellphones rather entertaining.
You actually have a few better polar alignment options on your Windows computers, some free, some that cost minimal outlay. They work through your primary camera, or your guide camera if you have one. All of them however allow you to get dead accurate polar alignment. All of these solutions use plate solving for polar alignment, and they negate the need for you to place Polaris right where it needs to be in the polar scope graticule. You only need to place it in the field of view of your polar scope. The software takes it from there. NINA and APT can also polar align even without needing to be aimed at Polaris!
The first, free except possibly for it's learning curve, is NINA. With NINA and some free support astrometry apps, you can plate solve polar align.
Similarly, the $20 Astro Photography Tool has "PAPS", Polar Align via Plate Solving 3-points polar alignment, also using some free astrometry support apps.
Finally, there is the $15 US/year subscription-based SharpCap, with a 2 point polar alignment tool.
With any of these apps you only need to put Polaris roughly where it needs to be, and the software will guide you to a perfect polar alignment.
All of these apps offer many additional tools sets, like camera control and capture. I'm not too familiar with Sharpcap's entire tool set, but both NINA and APT offer a multitude of tools for an astrophotographic session, like plate solve GOTO on dual axis mounts, camera control and image capture, focusing tools, mount dithering, capture data analysis, planetary capture, etc. If you happen to have a guide camera and guide scope, you can additionally run PHD2 and it integrates with these apps for autoguiding and dithering. Using an app like Stellarium or Carts du Ciel, you can also manually plate solve GOTO to position to accurately position your camera and SkyGuider Pro to your target.
I could go on, but you get the idea. I think this is probably a better way for you to go to get accurate polar alignment and target positioning then what you're trying to accomplish. So have a look at these apps, watch some tutorials for NINA, APT, and SharpCap, and see which one of them "clicks" with you, and roll with it. My favorite of these is APT, and I highly recommend it.
