Kaffedex converging an espresso in two pulls, start to dial-in
From pull to decision
Calibrates from your pulls. Not a crowd average.
Kaffedex watches two pulls on your gear and derives a per-burr sensitivity from your actual shots — no guesswork, no crowd data, no internet required. The same engine now works for espresso and pour-over on the same bean.
Get the move
Explicit finer/coarser direction in your grinder's native clicks or marks — not just a vague "go finer."
Brew again. Dialed.
Make the suggested move, log the result — converge in 1–2 brews instead of a dozen wasted shots.
Two brew methods. One engine.
Espresso and pour-over — both fully dialed in.
The latest update ships filter and pour-over as a full second pillar. The same offline calibration engine that dials in espresso now guides your V60, Switch, flat-bed, and any hand grinder you prefer for filter work.

Shot dial-in
Log dose, yield, and time. Get the next grind + dose move in your grinder's native clicks. Calibration lives on your burr — swap to SSP, Mizen, or any aftermarket set and the math follows. Converge in 1–2 shots.

Questions
The useful answers, up front.
Does Kaffedex require an account?
No. Kaffedex does not require an account or login. Your data stays on your device and syncs via iCloud if you choose.
Where is my coffee data stored?
Your beans, pulls, recipes, and notes are stored on your device with optional iCloud sync. You can export a backup from the app at any time.
Does it work with my grinder?
Kaffedex includes presets for a wide range of espresso and filter grinders — including multi-mechanism hand grinders like the 1Zpresso ZP6 and Kinu — and native adjustment units for each. If your grinder isn't listed, you can enter your own steps. After two pulls with a meaningful grind change, the app derives a per-burr sensitivity from your own data and uses that instead of the preset.
Does it support pour-over and filter coffee?
Yes. The latest update ships filter and pour-over as a full second pillar: per-model dripper icons, ratio wheel, per-pour journal, paper cross-compatibility guidance, and a guided brew player with vessel simulation and teleprompter pour cues.
Can I import a recipe from a card or QR code?
Yes. Tap the QR scan option in the recipe importer and point your camera at a Kaffedex recipe card — the app reads the code automatically. (Importing a QR from a saved photo in your library is coming in a future update.)
Does it connect to coffee hardware?
The core dial-in engine works entirely offline without any hardware. Supported Bluetooth scales can send weight and time readings directly into a pull log if you want them.
How do the optional AI features handle data?
Only the relevant request content is sent for processing when you choose an AI feature. Kaffedex has no advertising and no third-party analytics.
What's free and what's Pro?
Free: unlimited bean and pull logging, full rule-based dial-in suggestions, all filter and pour-over features, iCloud sync, and manual Agtron entry. Pro: varietal-density library, taste-note AI coaching, and the fully guided filter bundle.
