I find this app to be very accurate, useful, and simple to use. I use it all the time to make sure I dont get over a certain BAC by tracking every drink. I especially use it if Im out with the car so as to never be close to a DWAI. With todays stronger beers its easy to be "over the limit" surprisingly quickly and this app helps prevent that. Highly recommended!!
