In the meantime keep funding fledgling companies and we'll choose from the abundance of HN apps already available. :)

Do you have a favorite? The one I liked and paid for hasn't been updated in a long time and is essentially broken.

I switched to news:yc recently and am very happy with it.

Ahhh, thanks. That is just what I was looking for.

The other problem I've encountered on mobile devices (and even occasionally on a PC with a mouse) is that the voting arrows are small and quite close together, making it rather easy to hit the wrong one.

One possible solution would be to have only the arrow you click disappear, so you could always hit the other one and at least cancel out your own vote if you made a mistake.

HN already is a mobile-optimized version (except possibly the up/down arrows). No need to waste your time.

EDIT: Well, the community has spoken.

You think? On my iPhone, the page width is about twice as wide as would be comfortable to read, so either you read tiny print or zoom and scroll constantly.

Shoot, I'll do it for you for free.
