Features
Guided timer
From the bloom to the last pour, the cumulative target fills the screen. Two strong taps tell you when to pour, so you don't have to watch. Also on the Lock Screen and in the Dynamic Island.
Bean cellar
See when each bag is at its peak from the roast date, and the remaining grams go down every time you brew.
The next move
Tap the taste map after brewing, and get one change such as "grind one step finer", with the reason, based on extraction and strength theory.
Classic and custom recipes
Three pours, bloom plus one, a five-pour split recipe, immersion, and flash-chilled iced coffee. Change the dose, and the water is recalculated.
Journal and trends
Rating trends and a scatter of tastes on the map. Add brews made with another timer, and export CSV.
