Privacy Policy: https://grindconverter.pages.dev/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Notes: Results are reference ranges.

Record one or several whole bottles at once in the milk library. For larger cartons, log partial use, finish the remaining milk, and undo the current action. Inventory, costs and reminders remain free. Pro enables editing protein, fat, lactose and lactose-hydrolysis details; saved details remain readable after a downgrade. New milk inventory: track products, cartons, individual bottles, opening times, use, losses and stock corrections. Optional local reminders distinguish packaging guidance, personal deadlines and conservative defaults; they do not certify food safety. Mark beans finished, keep their history and reactivate them. Pro's bean workbench adds method grouping, favorites filtering, two-cup comparison and quick repeat as a new draft. Free retains manual logging and ordinary history within existing limits. Free espresso prediction uses standard 1:2; other styles and ratios require Pro. Existing recipes and records are preserved when Pro ends. Saving a new brew now adds a rough composition estimate to the coffee calendar. Undo or delete personal intake without deleting the brew. Selecting a historical brew in the Pro calculator does not add intake unless you save it. The Pro calculator now gives rough caffeine and cafestol values for valid supported recipes, with explicit assumptions and ranges. These are model estimates, not measurements or medical advice; actual values may differ substantially. YanMore Grind brings adaptive grind calibration and a coffee notebook into one practical tool. BAYESIAN CALIBRATION The recommendation workflow combines a Bayesian learning model with equipment, bean and recipe context. Eligible brew observations help inform the next adjustment. See a suggested setting, the direction and size of the change, its reasoning and the strength of the available evidence. Stepped, stepless and dual-mode settings retain their own adjustment semantics. MORE THAN ESPRESSO Supported methods include espresso, pour-over, moka pot, French press, AeroPress, drip, cold brew and siphon. Espresso basket profiles describe resistance and geometry without being applied to other brew methods. YOUR COFFEE NOTEBOOK Use the app simply to keep brew notes, or build a calibration history. Save beans and equipment, dose, beverage weight, time, temperature, tasting scores, free-text notes and flavor tags with intensity. Review past brews and recent adjustments; share records or reference recipes and keep local backups. Imported recipes remain references, not measured results. FREE AND PRO Free lets you use one grinder, chosen from the catalog or created manually, two bean profiles, and your latest 20 visible records. It includes espresso and pour-over, the standard double espresso basket, basic text sharing, and export of all your data. Pro adds more grinders, all supported brew methods, advanced baskets and parameters, full history, advanced sharing, and complete backup import and restoration. Existing records remain stored and exportable when Pro access ends. The core recommendation logic is the same for identical available inputs. Core recording and recommendations work locally without an app account. Apple handles Pro purchases and subscriptions; current prices appear in the app. Suggestions need validation in your next brew. Sparse or conflicting history can require more observations; there is no promised accuracy or fixed number of cups.
