SCALE TIMER AND BUTTONS On scales with a built-in timer, START, PAUSE and RESET in the app start, stop and reset the timer on the scale, so both count the same seconds. On Acaia, Decent and Varia scales the timer button on the scale itself controls the brew in the app.

WHAT YOU SEE WHILE BREWING

• beverage weight
• coffee dose weight
• brewing timer
• brew ratio
• flowrate, in grams per second
• charts for total weight and flowrate

MADE FOR Espresso, pour-over and drip. Save the dose with one tap and watch the brew ratio while you pour.

DESIGNED FOR ONE HAND Every control sits at the bottom of the screen, in the reach of your thumb - no need to shift the phone in your hand in the middle of a pour.

AUTOSTART The timer can start by itself on the first drops, so you never miss the beginning of the brew.

ACCESSIBILITY Dark mode, Dynamic Type and full VoiceOver support.

PRIVACY No account is needed to use the app with most scales, and no data is collected. The Xiaomi HOTO scale is the one exception: it transmits weight only inside an encrypted Bluetooth session whose key is issued by the Xiaomi cloud, so the app asks you to sign in with your own Xiaomi account. Those credentials go straight to Xiaomi over HTTPS - we run no server of our own and never see them.
