Find the shot once.
Pull it forever.
iopa is a precision dialing-in studio for home baristas. Track every variable, learn from every shot, and stop re-discovering the same recipe with every new bag.
```Pull again.
Built for the way you actually dial.
Most apps ask you to fill in a form after every shot. iopa watches the shot happen, captures the variables that matter, and tells you which knob to turn next.
Every shot, on the curve. In real time.
Connect your Bluetooth scale and iopa starts recording the moment the basket starts dripping. Yield, flow rate, time, pre-infusion duration, ramp-up — captured at 10Hz, plotted live, archived forever.
- Acaia Lunar, Pearl S, Pyxis · DiFluid · Decent · Felicita
- Pressure inferred from flow profile when no sensor present
- First-drip auto-detect; manual start as fallback
- Compare any two shots side-by-side, frame for frame
Every variable. Every bag. Every time.
A recipe in iopa is not a screenshot of a spreadsheet. It is a living object that knows its bean, its grinder, its puck prep, its temperature curve, and its tasting verdict — so the next pull on the next bag picks up exactly where you left off.
- Dose, yield, time, ratio, temp, grind setting, basket
- Tasting wheel with 134 SCA-aligned descriptors
- Pressure profile import & channel detection
- Pinned recipes carry across new bags of the same coffee

Tell it the taste. It tells you the next move.
Every shot ends with a question: was it sour, balanced, or bitter? Did it taste hollow, or did the finish drop off? iopa's adjustment engine learns from your verdicts and the verdicts of 4,200+ baristas before you — then proposes the next single-variable change.
- Single-variable suggestions, never compound changes
- Confidence score from your prior bags & the global cohort
- Adapts to your machine, your grinder, your water
- Optional: refractometer feedback closes the loop
Your shelf, finally on file.
Scan the bag. iopa pulls origin, process, varietal, altitude and roast date from 200+ partner roasters. The library tracks days off-roast, dose remaining, and which bag is peaking right now — so you stop opening that fourth bag of Geisha by accident.
- 200+ specialty roasters with QR/NFC bag support
- Days-off-roast curve flags peak window per bean
- Auto-decrements dose remaining after each shot
- Retired bags archive with full shot history attached

The details that make it yours.
iopa is built on the assumption you have opinions about water, equipment, and which scales actually transmit reliably. So do we.
Bluetooth scales that don't drop.
Every supported scale is tested weekly on iOS, iPadOS, and macOS for connection stability, weight delta accuracy, and timing offset. We publish the results.
Water profiles, tracked.
Save your TWW recipe, your tap, your bottled blend. iopa adjusts extraction targets per profile.
How often you nail it.
Daily & weekly summaries; trends per bag, per grinder, per water profile.
Scan the bag. Skip the form.
QR & NFC on 200+ specialty roasters. Origin, process, roast date — auto-filled.
Machines & grinders, profiled.
Every shot inherits temperature offsets, basket size, and grind step from the equipment that pulled it.
Your morning, visualised.
A quiet heatmap of your routine — color graded by avg shot quality. Spot the days you peak, the days you drift, and the bags responsible for both.
TDS & extraction yield, imported.
Drop a reading from your VST or DiFluid Omni and iopa closes the loop — every shot scored against actual extraction yield, not just taste. The engine learns faster when you give it the math, but works perfectly without it.
The people who already got their morning back.
iopa is in private beta with home baristas and working professionals. A few of them said yes to being quoted.
