Duo Coffee

Duo Coffee is an espresso machine you can fold and put in your pocket — and the loveliest way to keep count of your coffee.

Tap a button, watch the shot pour, tap the full cup to drink it — and every cup and every milligram of caffeine is counted. On iPhone Duo, fold the phone and it becomes the machine.

BUILT FOR iPHONE DUO Fold your iPhone Duo and the front of the machine stands up while the cup sits on the table — the stream crosses the hinge into it.

Stand it in a tent on the counter and it turns into a big pour-over timer, your month as stacks of cups, or your coffee selfie.

A COFFEE COUNTER • Every cup you drink counted, along with its caffeine • Today against a daily limit — 400 mg by default, and yours to change • Stats by day, week, month and year • A shelf of the very cups you drank, stacked by day — shake the phone and they tumble • Optional: save caffeine to Apple Health

POUR-OVER TIMER V60, Chemex, French press and AeroPress, step by step around one big dial: bloom, pour to 150 g, drawdown. A chime at every step and a tick before it, so you can pour without looking.

COFFEE SELFIE Take a selfie or pick a photo. Your face is cut out and set among every cup you drank this month, with the count and milligrams in big type. Made to share.

BASE: 7 machines and 6 cups, the counter, the timer and the selfie.
