Probably a good idea to use normal screen dimensions for the demo too. Was a bit thrown off by that.

I’m in bed at the moment and tried to watch the video but stopped as soon as I realised it needed audio to be understood for fear of waking my partner. It does look like a cool app though! Maybe some gifs with captions for each feature would be helpful?

Would also recommend trimming the silence off of the beginning of the video and show b-roll in the background while introducing the functionality of the app.
