Sound familiar?

“My popper roasts too fast”

Short-batch timing bands and heat-management tips built for unmodified poppers — and profiles that understand a dimmer mod when you add one.

“Is this even worth logging?”

The roasters who improve fastest are the ones with notes. Two taps per roast is all it takes.

“What should I buy next?”

The Equipment Advisor matches your budget and style — and your popper history seeds your next machine's profiles.

One app, from green bean to brewed cup

Inventory, roasting, ratings, blends, brewing, and coffee education — offline, private, and yours.
