Hi. Great app. But might i give a suggestion. When you add drink, the bac should rise within the next 30minutes or so, and the start to go down. I think this would make it more accurate as it takes some time for alcohol to get into the bloodstream. An example would be if one takes 2 shots at once. In this app you will get a huge spike the second its entered and it will count down to a 0% bac much sooner than in real life. So to add delayed uptake will just improve the app. It could be an bac now and estimated max bac. Also it would be good to have 4-5 favorites on the main page. As one often drink the same beer drink over and over. Then one do not need go back and forth between different screens. Saves many clicks, will improve ux. History can be moved bellow favorites. My 2 cents.
