Tensor Coffee

Take total control of your espresso. Pair with the Tensor One, build brew-by-weight and brew-by-time profiles, customize your display, and dial in repeatable shots.

Tensor Coffee — the companion app for your Tensor One + La Marzocco Linea Micra espresso machine.

Tensor Coffee is the official app for the Tensor One precision controller, the engineering-first performance upgrade for the La Marzocco Linea Micra. Where the controller gives you one dial and total control at the machine, this app is where you set everything up: pair your device, build and fine-tune extraction profiles, personalize your display, and keep your favorite shots a tap away.

Connect over Bluetooth and turn guesswork into data-driven espresso that's repeatable to the gram.

PAIR AND CONNECT Find your Tensor One over Bluetooth, connect in seconds, and remember your devices for instant reconnection.

BUILD BREW PROFILES Create and edit the recipes that run on your machine. Design brew-by-time profiles to run a precise extraction on a timer, or brew-by-weight profiles that stop on a target mass when paired with a compatible Bluetooth scale. Set your dose, yield, and ratio, image, and name each profile.

CUSTOMIZE YOUR DISPLAY Upload your own images to the controller's integrated display and assign them to profiles. Crop and frame photos right in the app, manage what's stored on your device, and make every recipe instantly recognizable on the dial.

DEVICE SETTINGS Tune your controller to taste. Adjust display brightness, set how many profiles appear on the dial, choose your system accent color, toggle flow control, and load calibration data — all from your phone.

GUIDED INSTALLATION Step-by-step, illustrated installation instructions walk you through fitting the Tensor One to your Linea Micra, with a clear progress tracker so you always know what's next.

DESIGNED IN ZÜRICH Tensor Coffee products, including the Tensor Coffee iOS app and the Tensor One physical device are designed and built in Switzerland for people who treat espresso as a craft — replacing manual guesswork with precise, repeatable extraction, shot after shot.

Requires a Tensor One controller installed on a La Marzocco Linea Micra. Brew-by-weight requires a compatible Bluetooth coffee scale. Bluetooth must be enabled to connect.
