At the risk of violating your diktat in your last sentence -- Would https://www.mtailor.com/ https://www.mtailor.com/ meet your expectation? They don't have subscription, I think. But they keep your measurements, so you can reorder from the app. I ordered a shirt a few years ago when I lived in the US, was happy with the fit and finish. I have moved out of the US and so haven't used them recently though.
