User reviews

Simple and useful

Really handy little app if you use more than one grinder. I mostly just wanted a grind setting converter without a bunch of extra stuff, and this is exactly that. Works well for my c40 and 1Z ultra; dining experiments on my niche and timemore. Very simple but useful tool.

Perfect

It’s very professional for coffee grinder can help us control grind size, and get better flavor and aroma from beans.

Super handy tool for dialing in recipes

As someone who brews coffee at home pretty often, this little app has actually been really helpful.

I’m always experimenting with different beans and recipes — V60, AeroPress, sometimes espresso — and each method needs a slightly different grind size. On top of that, I have more than one grinder at home, so when I see recipes online it’s often hard to translate someone else’s grind setting to my own grinder.

That’s where this app really shines. Being able to convert grind settings between different grinders makes dialing in a lot easier. It gives me a solid reference point so I can get close to the right grind size without wasting too many shots or brews.

The interface is also super simple. No unnecessary features — just pick your grinder, convert the setting, and you’re done. It’s quick and straightforward to use.

I’ve tested it a few times while adjusting my recipes and the suggested grind ranges have been pretty accurate compared to what I normally end up using.

Also, the price is very reasonable. If you like experimenting with different recipes or use more than one grinder, this is actually a really handy little tool.

Simple, accurate, and easy to use. Definitely a nice utility for coffee nerds.
