RockhoundID

Early access

The RockhoundID app is on its way

Snap a rock, see the likely candidates, and confirm the answer with one quick test. iPhone first, then Android.

What it will do

What it will not do

It will not promise a certain identification or put a price on your rock. A photo cannot show hardness, streak or weight, so the app will ask for a quick test when it matters, and it will point you to a museum, a rock club or your state geological survey when a find deserves an expert.

You do not have to wait for the app. The rock identifier works from a few quick answers, the Mohs hardness scale shows what scratches what, and the meteorite checker gives honest odds on a possible space rock.

Fun fact

Hardness is the clue a photo can never see. A glassy white chunk could be quartz, calcite or glass, and a copper coin and a piece of window glass tell them apart in seconds.
