Visual and audio feedback is great for your brain.
For me, I often need to make a 200mL bottle for my child, and each scoop of powder makes only 20mL - meaning that I need to put 10 scoops in. Especially when I have a crying baby it's easy to lose track when you count in your head. But no worries if I vocalize my count.
