My team is just me. And I'm a lousy, but improving designer. I essentially find a site I like, and then "borrow" design elements from it. I don't scrape or steal - just take some direction. Without it, I'd never be able to get started.

I'm slightly ashamed to publicly admit this, but my design is a poor imitation of what I think is a rather good design here:

I took some cues from them, simplified it so that I could actually do it myself, and then stopped improving it when it was no longer absolutely embarrassing.

The logo is just Arial. Go figure.

I have since redone it almost completely, and I think the new one is much better, but like I said, you won't be able to see it until sometime later this week/next week.

The new design is much more focused and less scattered. Each page has a clear point to get across. Aesthetically, it's nicer as well, although I've confirmed that with precisely zero people.

As far as the app itself, I just made that up from scratch.
