Grindstep vs Watermelon Maestro

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.

Knock, listen, choose. Watermelon Maestro uses your iPhone's microphone to analyse the sound of your knock, measuring its pitch and how long it rings, then shows you a sweetness dial and a plain verdict from Skip It to Buy This Melon. Deep and resonant means ripe; high and short usually means unripe. Grounded in published acoustic research, with a five-step illustrated picking guide and seven languages built in. One-time purchase, works offline, no account required.
