Dial in espresso beyond vague advice. Grindstep learns how your grinder responds, recommends specific next settings when ready, and shows the math. No account. Dial in espresso with a clear next step—not another vague “grind finer.” Grindstep is an espresso shot log and grind calculator for home baristas. Record what happened, learn how your grinder changes shot time, and get a specific setting adjustment once there is enough history. Every quantitative recommendation includes the math and confidence behind it. LOG EACH SHOT, THEN KNOW WHAT TO CHANGE • Record grind setting, dose, yield, brew ratio, time, temperature, TDS, and taste • Use the built-in shot timer and repeat your last setup • Get free directional guidance from taste and timing • Unlock quantitative recommendations based on your own grinder data START EACH BAG CLOSER First Shot Forecast uses your previously dialed-in bags to suggest a starting grind setting. The source is always shown, so you can judge the suggestion before using it. SEE YOUR DIAL-IN PATH • Follow every bag from first pull to locked recipe • View a Brew Control Chart with measured TDS points or clearly marked estimated regions • Track roast age and see how your dialed setting moves over time • Freeze a bag without letting its roast-age clock keep running BUILT FOR THE MORNING RUSH Save bags, grinders, machines, recipes, costs, and tasting notes without turning each shot into paperwork. With Pro, widgets and Repeat Last Shot make your usual workflow faster. PRIVATE AND PORTABLE No account is required. Your coffee data stays on your iPhone. Import compatible coffee logs and export your full archive as JSON or your shots as CSV.
