Stop wasting your first six shots. Snap the bag, get your starting numbers, be dialed in by shot two. And when the bag runs out, find the roaster again. SnapDial reads any coffee bag label (roaster, origin, process, roast) and turns it into a concrete grind, dose, and yield recipe for your exact machine and grinder. No generic 1:2 advice: real numbers in your grinder's own units. NEW IN 2.0 • Roaster finder: hundreds of independent roasters in Germany, Austria and Switzerland. Search by city, postcode or roaster name and see how far away each one is. Nothing nearby? SnapDial shows the nearest roaster and who ships to you. • Buy it again: once a coffee is dialed in, the recipe shows where to get it again, one tap to the roaster's shop. • Household: everyone who shares the machine gets their own corrections and taste. Free, no limit. • Share card: send your dial-in as a picture. • Near me and map view of all roasters (Pro). Your location stays on your iPhone. WHAT YOU GET • Photograph a bag, get a starting recipe in seconds • One-question feedback loop: taste + flow → exactly one change • Grinder calibration that narrows in on your setup over time (Pro) • Add bags manually without a photo (Pro) • Multiple equipment setups: home and office (Pro) • Community starting points from other owners of your grinder (Pro) • Shot history: last 3 free; full timeline and dial-in stats (Pro) • Coffee school: process and roast basics free; flavour deepening (Pro) • Works in German and English SnapDial is free to use: limited bag scans per month, one equipment setup, last-3 shot history, roaster finder with search and distances, household profiles, basics education, full recipe engine and feedback loop. SnapDial Pro removes the limits and adds calibration, taste profile, manual add, community starts, multi-setup, full history and stats, near me and map in the finder, and the full education library.
