Looks like a cool app that could be very useful. Interesting work.

Suggestion:

Record a new demo video with what I am going to call "normal" contrast white background and light elements theme. Your demo is super low contrast and very dark. Hard to watch.

Take cues from the way UI colors work on computers as shipped to the average person. Nobody ships their OS with super dark low contrast everywhere. Just suggesting, if you intend to actually go to market, you might just turn off your average user.
