Update broke key feature

Update 5/21/2025: another update is even worse... now none of the saved images shows!!! 😡 Please fix it ASAP!

Latest update from May 2025 2.0.43 doesn't shows old images for individual shots. Please fix it asap!

Crashes, no way to edit water and update profile picture does not work

The app constantly crashes and no way to edit water. Which makes it useless. The idea is amazing but implementation so bad.

Frustrating App

I can’t get this to work properly, sometimes I can add a photo from my library other times I can’t. Don’t even get me started on trying to edit a picture. Please fix the issues with Brewmaster. iPhone 12 Pro, latest iOS18.

Crashes very often

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.

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.
