Good Espresso for Decent

Good Espresso is a complete espresso engineering platform — full Bluetooth machine control, real-time extraction monitoring, automatic shot recording, ML-powered quality scoring, programmable brewing profiles, multi-brand scale integration, and a GPU-accelerated computational fluid dynamics puck simulator — all in one native Apple app.

BLUETOOTH MACHINE CONTROL

Connect to any Decent DE1, DE1+, DE1PRO, or DE1XL over Bluetooth LE. Start and stop espresso, steam, flush, hot water, and descale. Adjust brew and steam temperatures in real time. Upload custom pressure and flow profiles directly to the machine. Sleep, wake, and monitor state from anywhere in range. Run calibration, cleaning, and descaling routines.

REAL-TIME EXTRACTION MONITORING

Live pressure, flow, and temperature gauges update during every shot. A dual-axis extraction chart plots pressure and flow against time so you can watch channeling and pressure ramps as they happen. Three-point temperature tracking: group head, mix circuit, and steam boiler. Automatic shot recording captures full telemetry the moment brewing starts.

17 BREWING PROFILES + FULL EDITOR

11 espresso profiles (E61 Classic, E61 High Temperature, Lever Blooming, Turbo, Advanced Pressure, Ristretto, Slayer Style, Allonge, Dark Roast, Light Roast, Flow Adaptive) and 6 pulse-brew tea profiles (Green, Black, White, Oolong, Pu-erh, Herbal Tisane) with gongfu-style steep/pulse cycles. Build your own: up to 20 steps per profile with pressure, flow, or steep mode, per-step temperature, transition type, and exit conditions (time, weight, pressure, flow). Search, filter, favorite, duplicate.

SHOT HISTORY & ANALYTICS

Every extraction is saved with full data points (pressure, flow, temperature, weight), duration, dose, yield, ratio, star rating, and tasting notes. An on-device ML pipeline built on Apple's Accelerate framework (vDSP) scores each shot 0–100 across four components: pressure stability, flow consistency, temperature control, and extraction efficiency — then generates grind adjustment suggestions and channeling probability. 12 customizable analytics cards including score timeline, shot comparison, trend charts, and weekly progress.

BLE SCALE INTEGRATION

Auto-detects Acaia, Bookoo, Felicita, Decent, Hiroia, Timemore, Skale, and generic BLE scales. Real-time weight display with flow-rate calculation, auto-tare on shot start, and auto-stop at target weight.

PUCK SIMULATION — GPU-ACCELERATED CFD (PREMIUM)

A real computational fluid dynamics engine solving Darcy's law with Kozeny-Carman permeability on a 76,800-cell grid via Metal compute shaders. Full transient extraction: 80 time-steps modeling wetting fronts, puck swelling, channel formation, fines migration, and viscosity feedback. 12+ interactive parameters, 5 visualization modes, and a 3D volumetric renderer. The same porous-media physics used in hydrology and reservoir simulation — on your phone.

$2.99/month with a free 7-day trial.

NATIVE ON iPHONE, iPAD, AND MAC

Tab bar on iPhone, sidebar on iPad and Mac. Adaptive dashboard. Drag-to-reorder tabs. Dark mode. VoiceOver accessible. Apple Watch companion.
