I just want to make my V60 coffee I found out that my electronic scale ran out of battery and there is no charger in my work location and I also work on a remote area nearest city about 100 km so, I grab my iPhone to find out is there any app can scale my coffee grams and water mills by putting coffee bin above the iPhone for measuring it’s weight. The answer is no, there are no apps for measuring weight of coffee bens and water droplets to make V60 coffee. Still I have made my coffee perfectly from my experience. I am writing this post just to have scale app at my iPhone and also if I can get some money it is good because no one can say no for the money
