Ok, I repent. I just rechecked Brew Guru. It has a more up to date map of breweries than does Untappd. I’ll keep it on my phone.
I was going to say that it has improved markedly. I find that its very useful for finding deals at breweries and tap rooms. Sometimes those deals are for food, beverage, or merchandise.
The other thing that is very useful is that there are listings of good recipes on the app. So you'll always have something handy to guide you when you find yourself at the homebrew shop and decide that you want to brew something.
