This is a really nice app for tracking alcohol consumption. It allows you to create your own drinks and then track them. I would suggest trying the app before heading out for a night of partying. It was easier to set up my own drinks while I had access to the internet on another computer. Learning to add each drink was also a learning curve. I may just be slow!
