GrindLab vs RoastNote

GrindLab turns your iPhone camera into a precision coffee grind analyzer. Snap a photo of your grounds and get instant, micron-level particle size measurements — no extra hardware needed. ANALYZE YOUR GRIND Use computer vision to detect individual particles and measure their size distribution. GrindLab calculates median size, uniformity score, fines percentage, and boulders percentage so you know exactly how consistent your grinder is performing. Calibrate with a coin or ruler for real-world micron accuracy.
