Hey myfitnesspal. The entire planet uses metric. I went to chef school in France, Canada and Morocco, it's all metric. I have no idea what an ounce is, or a cup, or whatever folk measurements you are using. Every home has a scale and every container in the world (except the USA?) has the amount of food measured in metric by weight or volume. If I am trying to measure the yoghurt I'm eating in the morning, I can look and see that i've eaten 1/3 of the 750 ml container, so 250 ml. Or I can throw it on the scale and measure that I ate 270 g. Now when I go to enter the food, I am presented with a million confusing serving types in an array of measurements that make no sense outside of the USA, and metric is often not an option. The serving sizes are not helpful when there is metric, it just adds extra math. I often have to make a bizarro choice like 0.8 servings of 300 ml of yoghurt, or 250 servings of 1 g of yoghurt. Just let me enter 250 g and be done with it. 250 servings of 1 gram is REALLY bad UX. On top of that, for unlisted foods there is a nutritional info box for carbs, protein, vitamin a etc, and it's all in metric as well. No way I am doing the math to enter this in. This app is unusable to me.
