## What is DOSE?

DOSE analyzes your coffee grind size from a single photo. Even a kitchen towel or napkin works perfectly. Measure your grind at home or at the café in seconds.

■ Measuring is simple

• Spread the grounds
Scatter your ground coffee evenly over a sheet of paper, a napkin, or a kitchen towel.

• Find good light
Natural light or bright indoor lighting is all you need. Just avoid harsh shadows.

• Set distance and angle
Follow the on-screen guide: hold the camera about 18–24 cm away and parallel to the surface.

• Capture
Center the grounds in the frame and take one shot. That's it.

■ What you'll learn

• Particle distribution
See D10 (small) · D50 (median) · D90 (large), mean, fines ratio, uniformity, and more — alongside a distribution histogram.

• Brew-method guidance
Get advice on grinding finer or coarser for espresso, pour-over, French press, and other methods.

• AI Barista insights (on supported devices, iOS 26+)
Reads your results and suggests how to dial in your next cup.

• Save and share
Save your analysis card as an image and share it.
