GrindLab vs Grind Finer App

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.

Grind Finer helps you get the best from your grind by turning your shot history into smart grinder suggestions. Log your shots, and the app learns your setup so you spend less time chasing the right setting and more time enjoying great coffee. How grinder predictions work Grind Finer uses your own shot data to suggest grinder settings. When you log shots with your beans, grinder, machine, and basket, the app learns what works for your equipment. When you start a new shot with the same setup, it predicts a grinder setting based on your past successful extractions. The prediction uses: Your equipment – Grinder, machine, and basket Your beans – Which coffee you’re using Your targets – Desired brew time and ratio (e.g. 1:2 espresso) The more shots you log, the better the suggestions. Using consistent names for your grinder, machine, and basket helps the app learn your setup and improve predictions over time.
