I move around the office all day and there are a lot of wifi networks, most of them flaky. I keep ending up stuck on a bad one for wherever I'm sitting and having to guess which to switch to. So I built roamr: it tells you which of your saved networks is actually best where you are, and why. You still switch yourself.
