Can’t actually read the description of the alcohol you are entering. Can’t actually count the number of beers you drink. Supposed to know the fraction of litres you drink when you have no idea because it doesn’t say on a glass. You enter the volume of alcohol you drink by fractions of litre which is dumb, so after a night out you are supposed to remember the number of beers and size of each glass or bottle or can. Would be so much better designed if there were presets of a pint, half pint, can (tall and small), glass of wine, shot or double shot. Not intuitive at all.
