Horizontal and Vertical photos taken at the same time with both cameras

I've been using the moment products and app for a long time now and love it! I recently came across another photo app tool for iphone photography which creates two independent files at the same time using both cameras to create a horizontal and vertical images/videos regardless of which way you are holding it. It's a really cool yet very simple feature. When I naturally hold my phone up vertically, I am not compromising the width of a native wide photo. I get both! This would be really cool to incorporate into the moment app where I get full controls over the outcome. (since this other app only uses the native processing options)

Maybe it could automatically flip to whichever way you are holding the phone or could be toggled back and forth if you have other things rigged on the phone and need a quick vertical shot while it's on a cage. Just an idea that would be a cool feature to make moment app more useful!
