Horizon isn't just about vertical vs horizontal video, it's about either being skewed to a diagonal. Consider how many videos (whichever general orientation) wobble 5-20 degrees off axis; that's what Horizon solves.

Compare those professional "unsteady cam" shots where there's lots of horizontal & vertical movement, but never any tilt.

This is great! I'm very surprised that it isn't anywhere on the site. Instead the focus seems to be on horizontal photos, which seems ridiculous since anyone can flip their phone sideways.

Now this is a feature I would pay for. I think marketing it as fixing vertical video may be a miss, but marketing it as steady cam for your phone is killer.
