Log every shot. Get one clear next-shot idea.
Dial-In logs espresso and runs its deterministic Coach offline on your device, without an account. Track dose, yield, grind, time, taste, TDS and extraction yield (EY%) through Prep, Pull, Measure, Refine and Taste.
Free Core
- Unlimited local shot and bean logging with notes, favorites, TDS, and EY%
- Free offline Coach for one controlled next-shot experiment
- Brew-ratio, TDS, and extraction-yield tracking
- Charts and multi-bean comparison
- Equipment profile, CSV export/import, and Light/Dark modes
Optional Dial-In Lab
Dial-In Lab is a one-time permanent local toolkit, not a subscription. It adds a named Recipe Vault with revisions and prefill, controlled consecutive-pull Sessions with immutable recaps, optional advanced shot fields, a descriptive local Consistency Lab, freshness context, multiple gear profiles, and maintenance reminders.
Lab data and calculations stay on the device and can be read or exported after a refund or revocation; creating or changing Lab artifacts and generating new Lab analytics require active ownership. Every Free Core feature remains free.
Your data stays on your device
Core logging, Lab artifacts and calculations, and the deterministic Coach stay on your device. The free Coach and every Free Core feature work without an account or a remote service. Dial-In does not display ads or use cross-app behavioral tracking.
Delete All Data clears shots, beans, equipment, Lab artifacts, and Coach data offline. CSV export/import covers Free Core shot and bean data; a separate local JSON export covers Lab artifacts and advanced fields.
Optional support
