Green crab molt timing

Find peelers before they molt.

MoltMeter estimates how close a green crab is to molting from a photo or camera view, helping crews learn the visual signs and choose crabs for soft-shell harvest.

Simple Field Check

Use a clear top or underside image. The app estimates days until molt and labels whether the crab is in the peeler window.

Training Aid

Watch the MoltMeter detections to learn how to find peelers yourself!
