Coffee Tools

Brew by numbers,
not by luck.

Grind targets in microns, translated to your grinder's own clicks and adjusted by the brews you rate. Your dial-in stays when you close the app, so the next cup starts from it.

mikron running on iPhone. The Grind screen recommends 32 clicks — 969 microns, a coarse grind like flaky sea salt — for a Moccamaster, a Comandante C40 MK4 and a bag of Huila Pink Bourbon, and marks that recommendation ‘tentative’. Below it the app recalls ‘you brewed 30 at ~1000 ml last time and preferred 1 click finer — that’s 29 here’ beside a Use 29 button, and the Adjust brew row notes a medium roast, volume-aware 1000 ml and personal calibration.

Why mikron

It learns from the brews you rate.

In mikron every brew you log sharpens your grind target, remembers what worked, and tracks where your beans are in their life.

Tunes to your grind

The more you log, the closer the target moves to the setting that works for you.

Remembers your last brew

Your most recent result surfaces right where you grind, so each cup starts from the last one.

Tracks each bag’s peak

Roast-date aware to the day. It shows every bag’s peak window, so you brew it when it tastes its best.
