## What is YanMore Grind?

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 includes one editable grinder, selected from the catalog or created manually, two bean profiles, the latest 20 records, espresso and pour-over, the standard double espresso basket, basic text sharing and basic export. Pro adds the full supported methods and grinder catalog, advanced baskets and parameters, full history, advanced sharing, and complete import, export and backup restoration. Existing data is retained 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.

### 5/5 — 太赞啦！

*2026-09-17*

非常特别实用的app 界面简洁便于操作 但是参数记录可以非常细致 感觉像把研磨咖啡当作科研一样有仪式感的过程

### 5/5 — A little direction goes a long way

*2026-09-17*

As someone still learning about coffee, I don’t always know where to begin with grind adjustments. Having a recommendation to work from makes the process feel less intimidating. I’m not expecting an app to make every decision for me, but a little guidance helps. This is the kind of tool I appreciate: something that supports learning rather than making coffee seem even more complicated.

### 5/5 — On-device calculations are a nice touch

*2026-09-15*

The fact that the recommendation calculations run on the phone is something I genuinely appreciate. For a focused utility like this, that feels like a sensible design choice. My main interest is getting help with grind settings, not adding unnecessary complexity to making coffee. It's nice to see an app built around a concrete task with a straightforward purpose.
