The Smart Espresso Profiler is an easy-to-use tool to record and improve your espresso extractions. It gives all compatible espresso machines capabilities, which were only seen in the most advanced, state-of-the-art devices. Imagine perfectly repeatable pressure- and flow profiling with a modified vintage lever machine, or a modern pump machine, with instant feedback. Now you can log even your Decent Espresso shots on machines equipped with the Group Head Control. Decide whether you go with pressure, or with flow profiling - with the Smart Espresso Profiler, everything is possible. The Smart Espresso Profiler displays and records in real-time the pressure and flow of the coffee extraction, translating this information into pressure and flow graphs. It even informs you about the key indicators (brew ratio, flow rate, etc.) during the brewing process. Record all your experiences with the tasting notes feature, included in the app. Save and share profiles and notes of your favorite extractions. Set an earlier profile as a reference to follow. IMPORTANT: The Smart Espresso Profiler needs a pressure sensor to work, available at https://www.naked-portafilter.com/smart-espresso-profiler/ For flow profiling, and brew weight data, an Acaia Pearl, Lunar, Cinco, Pyxis, a Skale Bluetooth, a Eureka Precisa or a Decent smart coffee scale is needed.
