Needs much more descriptive tutorial

The explanation of the graph is poorly presented in the brewmaster section. It would be simple to just label each part of the graph and wrote a brief description of what it means/how to use it, but we don’t get that. This would be helpful for those using flow control devices

Lousy user experience

Whoever designed the app may have some basic experience with graphic design, but definitely not with user interface design. Frankly all I wanted was to see what my pour rates were on a graph to practice pouring at 6-8 g/s. It was such a p.i.t.a. to do this. (((and that text soooo tiny)))

Really not even a diagnostic or basic screen just showing scale data like that BIG somewhere?

Has programming API been made available or documented? I’ll write my own.

App crashes so frequently its almost useless. Please reach out to me if you would like a professional app thats as nice as the lunar scale.
