ROAST TO CUP · OLLA PRO

A roastery workbench for professionals.

For small coffee teams and independent roasters: from a bag of green to a cup, every move lands in one ledger.

INVENTORY

Inventory, one ledger

Green and roasted on their own layers, every bag with a code, cost and valuation always in view.

Intake · counts · splits. Sales and write-offs on one row.

PRE-ROAST DESIGN

Pre-roast design and curves

Settle the roast before you charge: turn the dials, and the windows and weight loss are worked out on the spot.

  • Live logging and curve import

ASSESSMENT

Assessment and experiments

Multi-sample blind assessments bound into a report; roast experiments chain several roasts into traceable evidence.

Blind assessments. Roast experiments: question · roasts · conclusion.

WEB / APP BOUNDARY

Where the Web stops and the app begins.

On the Web you try the design flow on OLLA demonstration curves and read a precomputed projection on the spot, always from the generic prior; designing with your own curves and machine is for the app. The results on the Web come from the same algorithm the app runs. Binding a machine, calibration, saving and the ledger itself live in the app.

Available since OLLA 1.3.0

FAQ

Three things worth settling first.

Will the roast and inventory records I already have be locked?

No. Records kept before 1.3.0 can still be viewed, compared, edited, deleted and exported in a JSON backup; only adding and delivering are closed.

I have no roasts of my own yet — can I still look around?

Yes. The first visit to the roasting tab fills this device with a demo ledger from an invented roastery. Demo data stays on the device, never reaches iCloud, and is cleared the moment you become a member or erase your data.

How is the subscription managed?

Monthly, annual (with a 7-day free trial) or a one-time buyout, priced by your App Store region. Payment is handled by Apple, and a subscription can be managed or cancelled at any time in iOS Settings.
