Identify minerals, crystals, and rocks
Rock Identifier by Photo is a free educational app. It allows users—from geologists and students to hobbyists—to identify rocks, minerals, crystals, gems, and stones just by taking or uploading a photo. Instantly, it provides a list of possible matches, letting users choose the one that best resembles their specimen.
Identify and save specimens
Developed by Negroni, Rock Identifier by Photo lets you identify rocks, gemstones, minerals, and crystals simply by taking a photo or uploading an image from your gallery. Whether you are a geologist, hobbyist, student, or curious learner, you can use this app to instantly discover the name of a particular rock, gem, crystal, or stone.
It also includes a built-in collection area to save favorite identifications, functioning as a personal rock journal. However, multiple users report wildly varying identifications—even from the same photo—undermining reliability. Additionally, this platform contains frequent and intrusive ads, which can disrupt the user experience.
Fun and educational, but inconsistent
Rock Identifier by Photo offers a convenient, photo-based way to identify rocks, minerals, crystals, gems, and stones, making it appealing to students, hobbyists, and curious learners. While its collection feature is useful, inconsistent identifications and frequent intrusive ads limit reliability, making it better suited for casual exploration rather than serious study.
