Super simple, bare bones, but surprisingly packed with options. This app is perfect for someone who is dialing in a pour over recipe, trying out new roasters, cupping, or any kind of dialing in. It gives you free range to create basically any kind of variable you want, and then gives you a comprehensive section to record what you noticed about the brew. Makes it really easy to adjust slight things in your recipe the next morning to try to tease out the notes you see on the bag. There is a simple timer if you need it and it works great. Thanks!
