AlcoWidget BAC Tracker

"Alco Widget” is the only widget available to measure blood alcohol content (BAC). On the phone's screen in real time you can see the current level of blood alcohol concentration and the time at which the concentration falls below a certain limit.
When you run the application, there will be permissible blood alcohol concentration limits automatically set in accordance with the laws of the country you are located in.
On the screen of your phone you can open several widgets at once to run measurements individually for your friends.
