About

Espresso Mirror

Features
Read full description

Espresso Mirror is a hands-free camera, shot timer, and pull log for dialing in espresso. RECORD THE PULL Start the video before you touch the machine. Start the extraction timer exactly when the pump or lever engages. Separate recording and timer controls keep pre-infusion and the full workflow on camera without distorting shot time. WORK HANDS-FREE Say “Start recording,” “Start timer,” “Stop timer,” or “Stop recording.” Repeated commands are safely ignored. If “start” or “stop” could mean two things, the app asks you to choose. READ THE EXTRACTION Review time, dose, yield, ratio, pressure, roast, grinder setting, and notes. Shot history syncs through iCloud so you can compare pulls and dial in with evidence. EXPORT CLEANLY Save the finished video to Photos and share it in five restrained layouts designed around extraction data. Espresso Mirror has no account and no ads. A one-time Pro purchase unlocks clean exports and full shot history. COMPLETE DIAL-IN TOOLKIT • Tap the preview to focus. • Save and reuse beans, grinders, and espresso machines. • Record dose, yield, ratio, pressure, temperature, roast, grind setting, dates, and notes. • Rate pulls from one to five stars and filter history by bean name. • Preview five export styles, rotate video by 0°, 90°, 180°, or 270°, and see percentage progress while large videos render.
