I’ve been using BrewFather, I get good results now that I’ve dialled in my usual efficiencies, though I dont really care if my final numbers are slightly off the target, if it tastes alright i’m happy.

I really only started using it to do water chemistry calculations, but now it’s my main recipe builder/checker.

I mainly use it to get my brew sheet that I have on my boox tablet for brew day, the only time I’ve skipped having that brew sheet I forgot to add a major ingredient and screwed up a batch.
