Coffee-Sensor

The Coffee Sensor App is a free mobile app for espresso enthusiasts who want real-time visibility into every pull. It connects simultaneously to multiple Bluetooth devices — including popular scales (Acaia, Decent) and pressure sensors (Bookoo, Esprofile, Phoenix, Transdir) — and displays live weight, pressure, and temperature readings through beautiful analog and digital gauges. Shot programs let you dial in your recipe with target dose, flow rate, pressure ramp, and brew time, while live plots capture each extraction for review. Whether you're chasing a perfect 1:2 ratio or debugging a channeling problem, Coffee Sensor gives you the data you need, right on your phone.
