Interesting little app, although I wonder if the people who would actually need it, would actually use it.
The question I have is about it's accuracy and repeatability. It doesn't look like it actually reports a number just one of 3 ranges. This is probably a good thing so we don't have people splitting hairs. But if the limits aren't quite calibrated correctly I can see a liablity issue (even if its free) if someone is busted for DUI and this thing didn't tell them. Yes, I know that that is not the purpose of it or how it is SUPPOSED to be used, but I also know that those who might be needing this on a regular basis won't care.
