What's New in YanMore Grind

3.0.0

November 4, 2026

Version 3.0 is a major update for dialing in, brewing and recording your coffee. GRIND RECOMMENDATIONS Recommendations consider your coffee, grinder, brew method, target recipe and eligible measured history. Measured references, interpolation and trial starting points are distinguished, with adjustment direction and supporting evidence. A CONNECTED BREWING WORKBENCH Move from recipe and equipment selection to adjusting targets, grind suggestions and timers. Supported recipes scale quantities and stages; pour-over plans connect to stage timing and notes for the same cup. RECIPES AND GUIDES Brew with publicly shared champion recipes, including Tetsu Kasuya’s 4:6 and Martin Wölfl’s OREA. Supported recipes automatically scale water and stages to your dose, then guide the same brew with stage timers. Explore AeroPress competition recipes and sources too. New dripper and espresso-style guides explain equipment and reference ratios. Basic recipes and timers are free; selected professional features require Pro. BEANS AND EQUIPMENT Record an unfamiliar bag as a temporary bean and link it later. Keep bean histories, portions and storage, explore origins on your map, and manage equipment and preparation tools. FROM ESPRESSO TO DRINKS Continue from a saved espresso into a drink without recording the extraction twice. Explore more illustrated drink recipes, record actual ingredients and photos, and optionally manage milk inventory and reminders. COFFEE CALENDAR AND COMPOSITION Review consumption in the coffee calendar and explore approximate caffeine and cafestol information for supported recipes, with assumptions and ranges. Caffeine comparisons provide additional context. Estimates are not measurements or medical advice. MORE WAYS TO USE YOUR RECORDS Keep photos, flavor notes and brew history, explore aromas with the flavor wheel, compare cups and repeat a recipe as a new draft. Core functions work locally without an app account; optional iCloud sync requires an available account and storage. Some advanced features require Pro. Suggestions are starting points to validate with your next brew. Sparse or conflicting data can require more measurements; results are not guaranteed. APPLE WATCH View the paired iPhone’s current brew, timer and stages on your wrist, and start, pause, resume or stop the timer.

太赞啦!

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

A little direction goes a long way

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.

On-device calculations are a nice touch

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.
