The seemingly only purpose of this app is to avoid the checkpoints could be dangerous to those of us who don't drink and drive. They should pull any app.
Perhaps this was said someplace in the 11 pages so far, but since I didn't see it in the first 2, I'm posting it.
People are assuming that this app has no benefit, but to help drunks drive without getting caught. Let me paint some scenerios.
1. You note that you can't get home without passing a DUI check point, so you don't drink at all.
2. You drink a bunch, and figure out you can't get home without crossing a checkpoint, so you stay where you are until you're sober.
3. You drink a bunch, figure out that there are checkpoints, and find an alternate way home that involves less trafficked roads.
4. You are sober, but worried about the number of drunks on the road. You find a route that crosses a DUI check to decrease the number of drunk drivers you are likely to meat.
What do you think?
#1 prevents the problem to begin with.
#2 also prevents the problem
#3 admittedly assumes that the check point is set up in the busiest areas. But I think it's safe to assume the checkpoints are not set up on quiet side streets that no one frequents.
#4 works out quite well. It works out even BETTER if the drunks have the DUI app as well, because they won't be on the road up until the checkpoint either, not just after it.
In any case, I can't help but think that this app actually improves the safety of more people than it hurts, both for drunks and sober people.
And FYI, I'm 26 and been drunk once in my life. I didn't like it. I like being in full control of my body and mind

However, I LOVE good beer
