Love the way this app shows relative scales, but it is hard to read. If you dont use reading glasses you will be fine. For those who are a bit older: thin font, small point size, and low contrast font color all add up to frustration. Sad to see so much wasted space, even when zoomed.
I find it odd that zero or lower numbers are at the top. It would be more intuitive with lower numbers at the bottom.
