First of all, the app it's very interesting, I really like what how you play with the colors and make something that seems serious and not too fun in real life makes it fun here.
And regarding my bid: how you describe the video (fun and upbeat) I think it's better to go with a little animation explaing the steps will go better with the kind of design and feel you already have, thus the time and price of my bid.
The website, as you say, it would be really simple and would like to include most (if not all) of the assets used on the app so SVG or AI files would be really appreciated to make the job a lot faster.
I would really like to work with you and hope that you pick it!
