Now that I think about it - the iPhone camera (4S and above) has a resolution of over 1920 pixels in each of the two dimensions. Therefore, even in portrait mode, it should be possible to pull 1920x1080 pixels in a cropped landscape.
And, in fact, it offers 1920x1080 on every device with an A6 chip or higher. (So not the iPhone 4S or iPad 2.) Thus, it seems that it requires an A6+ for the processing power to handle 1080p recording with the auto-leveling and cropping, but it should be full-quality, even cropped, since it's cropping down to more-than-1080p pixels anyway.
Which, after watching the video, I see the "big sell" of it - video zoom. In portrait mode, you're "zoomed in", and by rotating to landscape, you can "zoom out".
The video doesn't show if you can sit in a "halfway rotated" mode for "partial zoom", though. I presume you can, since it appears to seamlessly handle the rotate.
That alone makes it worth 99¢ to me. Well, it would if I had a phone newer than a 4S, anyway... (Yeah, at 640x480, the 4S gets the short end of the resolution scale...)
