ColonyCam: Colony Counter

ColonyCam turns your iPhone into a fast, repeatable colony counter for petri-dish plates. Photograph a plate, get a count in seconds, and fine-tune until it matches what you see. Built on an ImageJ-grade image-processing pipeline (auto-thresholding, distance-map watershed, particle analysis), ColonyCam aims for counts you can trust — and gives you the controls to get there. One simple purchase. Every feature included. No subscription, no in-app purchases, no account.

Counts are estimates and should be reviewed by a qualified person for any decision that matters.
