On auto the two sides are differently enlarged. The ultra wide requires 175% enlargement to match the wide’s 100%. That’s a 7 to 4 ratio, with ultra wide on the left with 7 and wide on the right with 4. The result is garbage. I tried other numbers and they all gave mismatches. Unless I don’t get the concept of ratios, this app is broken for the iPhone 15 pro max used in landscape orientation.

Although the app has a method to capture a stereogram with iPhone X’s 2 cameras, I personally love using the manual stereogram capturing feature. It uses the iPhone’s main camera and you capture each view separately. Once you capture the first view (left), it overlaps the image while you capture the 2nd view, so that you can align the focal point, which is brilliant! I post a lot of my stereograms to Reddit.com/r/parallelview
