AngleMetric

Drop shape & contact angle analysis

Lab-grade contact angle measurement, right in your pocket.

Capture a droplet side-on or top-down and get a gravity-corrected contact angle from a Young–Laplace curve fit in seconds — with 21 CFR Part 11–ready records.

How it works

Figure 1 from the whitepaper: the two capture geometries, side-on for hydrophobic drops and top-down for hydrophilic drops
The two capture geometries — side-on for beading, hydrophobic drops; top-down for flatter, hydrophilic drops.
