Espresso Timer listens to your machines and times them for you.
Tap LISTEN, then make coffee. The clock starts the second your grinder or pump kicks in, stops when it goes quiet, and shows the real running time down to a hundredth of a second. Your hands stay on the machine.

I built this because my espresso kept drifting. Same beans, same setting, different cup. I'd been timing by feel. Once grind time and shot time are actually measured, every morning tastes like the good one.


WHAT IT DOES

Two clocks
· One for grinding, one for the shot. Each with its own target time and its own sensitivity
· Classic watch-inspired analog dial, plus a digital readout to 1/100 of a second
· Opens on last used clock

Detection that holds up
· The clock winds back to where the noise really began and trims the tail. You see your machine's time, not the app's reaction time
· Clatter doesn't count: portafilter down, cups, spoons. Only sustained noise starts the clock, Reset anytime
· Short pauses while dosing don't end anything. The clock just waits
· Tip: Works best with the iPhone sitting close to your machines

Target time
· Your target sits on the ring as a colored segment
· Tap the target button, then turn the outer ring like a click wheel. The hand jumps to your target and follows your finger. It locks again after two seconds or tap so nothing shifts by accident
· Or save a good run as your new target
· When you hit the desired target time the whole dial flashes and a tone sounds. The clock keeps running in case you realize that you need more

Calibration
· Run your grinder and your machine once. The app measures your room and both devices, then sets the trigger levels for your kitchen
· Repeat it whenever you like. You can also set both sensitivities by hand, with a live level meter

Small things that matter
· Tap the dial to start or stop by hand
· Autostart and autostop listening options
· The display stays awake while the app is open. Nothing goes dark mid-shot
· Haptics on every control, modern iOS 26 look, English and German – more to come

APPLE WATCH
· A real app on your wrist. It runs without the iPhone
· Same dial, same detection. Grind and shot are two pages you swipe between, with the bean and portafilter as small marks on the face
· Tap the window at three o'clock, then turn the crown. It locks again after two seconds or tap
· A firm double tap on your wrist when the time is up
· Target times stay synced on both devices, Device to device, no account, no internet. Switch it off in Settings if you'd rather not
· Tip: set the watch's Wake Duration (Watch settings > Display & Brightness) to 70 seconds and the display stays on for the whole shot
