TrueStone: Rock Identifier1.0.3 - App Store

Discover the rocks, stones, crystals, minerals and gemstones around you with TrueStone.

Take a photo or choose up to three pictures, and TrueStone will analyze the specimen and suggest its most likely identification. Review possible matches, compare visible characteristics and learn more through clear geological information.

IDENTIFY FROM A PHOTO

Photograph a rock, crystal, mineral, stone or gemstone and receive:

. The most likely identification
. Up to three possible matches
. Clear confidence labels
. Common and scientific names
. An easy-to-understand identification summary
. Similar specimens and distinguishing features

ADD MULTIPLE ANGLES

Some specimens can look similar from a single photograph. Add up to three photos from different angles to help TrueStone examine more visible details.

EXPLORE GEOLOGICAL FACTS

Learn about chemical composition, Mohs hardness, color variations, luster, transparency, streak, cleavage, fracture, crystal system, geological formation, common locations, uses, care and relevant safety information.

REFINE WITH GUIDED STONE TESTS

Improve uncertain results by recording optional observations such as color, luster, transparency, streak, relative hardness, cleavage, fracture, texture, size, weight and where the specimen was found.

ASK TRUESTONE

Ask follow-up questions about an identified specimen. Learn how to distinguish it from similar stones, where it commonly occurs, whether special handling may be needed and how to clean or store it.

BUILD YOUR COLLECTION

Save specimen photos, identification results, favorites, tags, dates, location notes, size, weight, personal notes, guided observations and follow-up questions in your private digital collection.

EXPORT YOUR COLLECTION

Create a printable PDF of selected specimens or export your collection as a CSV file. Save or share exports using the standard iOS share options.

DISCOVER CRYSTAL LORE

Explore birthstones, zodiac associations, symbolism and traditionally claimed crystal meanings in a clearly separated section. Traditional or spiritual beliefs are not scientifically proven and are not medical advice.

TrueStone does not provide professional geological identification, laboratory testing, gemstone certification, guaranteed authenticity or monetary appraisal. Valuable, hazardous or uncertain specimens should be examined by a qualified geologist or gemologist.
