I just saw the intro video. I agree with the key insight (I'm a psychology graduate, I'm basing it on that knowledge). Here's some raw feedback from an n = 1. I'm being as critical as I can here, because your project can take it. Personally, I don't think this is the final answer to the problem your solving but a good step towards it. I see some UX issues. It feels like I'm looking at a Blackberry (in a pre-Blackberry era) and not an iPhone. So in conclusion: you found a key insight that everyone missed, executed well on it, but I'm missing a certain polish. I wouldn't know what this certain polish is, otherwise I'd have told you. It's simply a gut feeling (and gut feelings are terrible at picking things apart). I know it sounds a bit nitpicky, but view it this way: your one step away from world domination as far your product is concerned in my eyes. I'd say in a sense that's really positive feedback, isn't it? --- I'm going to riff on this idea in my free time: how can visual layout information help recall? I mean, one quick thought I have is: you can also make a VR app for this. Not sure if that would be the way to go (I think not), but I can imagine how it could help.
