That's great feedback! We're a couple of engineers, so the marketing stuff isn't exactly our area of expertise. The current design is just an off the shelf jQuery mobile template to make prototyping easy while we focus on functionality.
I'm a dev too, but have some photoshop skills and have to learn this stuff myself. I can really recommend that one of you gets to know Photoshop/Pixelmator/Sketch and browses a lot of other product pages and apps (so you can "borrow" there.. stealing shamelessly is often a good idea ;)). A product needs someone who cares about that stuff.
