What it will do

• Likely matches from a photo. Ranked candidates for rocks, minerals, crystals and fossils, each with the properties that fit and the ones that do not.
• The next test, not a guess. When the top matches look alike, the app tells you which simple test separates them: a scratch, a streak, a magnet or a drop of vinegar.
• Meteorite reality checks. Possible meteorites get the same honest checklist as the free meteorite checker, plus advice on who can confirm one.
• A field journal. Each find saved with the place and date, and a reminder of the collecting rules for that kind of land.

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.
