An app to dial in your coffee grinder

Over quarantine, I got really into coffee. A key to good coffee is a good grinder. Good grinders need to create very uniformly sized coffee grounds, but so far it's been difficult to benchmark your grounds.

I came up with an app idea that would help you estimate the size and distribution of the coffee grounds your grinder produces. The hope is that it would help dial in your new grinder or act as a benchmark between grinders.

Any other coffee nerds out there who want to give my MVP a try?
