Makes my brew day much smoother!

I love using this app to run my brew day on The Grainfather. I’m able to monitor my brew day from anywhere in my house, and I can control my mash temperature with a touch of a button. It’s awesome!

Issues with recipe management!

Primarily the biggest problem with this app is how poorly it handles the simple task of starting a brew session and accurately logging brew sessions! The app is a kludge of really great looking tools which I am able to use and like individually. But the app falls short in the area of recipe selection when starting a new brew session. It is difficult to select your recipe! It is difficult start the actual brew session! Brew session versions get mysteriously generated and stored out! In general the app has been put together piecemeal and has lost obvious intuitive control of sessions causing you to restart the session. Then you end up with stored versions of the same recipe saved without a clue as to why!
You need to really clean up the session control aspect of the app! This is killing your product!

No recent reviews?

Shenanigans! No way I will update this app until actual reviews come out. Got burned the last time a major update came out. They took a perfectly working app and destroyed it with social nonsense and broke key functionality. This is a test to see if this review gets posted. Your move Apple / Grainfather.
