Bloom keeps your coffee shelf, brew timer, and journal in one iPhone app. Add a bag’s roast date to see an estimated flavor window, follow a timed recipe, then rate the cup. Brew Coach turns sour, bitter, weak, or strong into one grind, dose, or water change to try next. Each brew subtracts grams from the bag. Bag scanning runs on-device (iOS 26+). No account; optional iCloud sync. Free for 3 coffees and 5 recipes; Pro removes the limits.
