Is it a meteorite, or a meteor-wrong? Most unusual rocks people find are terrestrial. Meteorite Check helps you find out which you have, using a structured screening process built by people who handle real specimens every day. BEYOND GENERAL ROCK IDENTIFICATION This is not a generic rock identifier. It is a focused screening tool for one question: could this be a meteorite? It walks you through the same checks a specialist would run first, in plain language, and tells you honestly where you stand. HOW IT WORKS Answer a short set of physical checks: streak color, magnetism, density, surface features, interior metal, and more. The app rules out the common look-alikes first, then weighs what is left. Each check includes reference photos of real specimens and real meteor-wrongs, so you know exactly what you are looking at. HONEST BY DESIGN Your result is only as good as your answers, and the screening reflects exactly what you report, nothing more. No photo or kitchen-table test can classify a meteorite. Only a hands-on examination, and where needed laboratory analysis, can confirm one. A strong result here means your rock is worth a proper look. We tell you that plainly, and we tell you when a result is weak. OPTIONAL PHOTO ANALYSIS For a closer read, optional photo analysis examines the surface and any cut face of your specimen for the subtle signatures that point toward a meteorite and the disqualifiers that rule one out, then sharpens your result based on what it finds. A STRONG CANDIDATE? HERE IS THE NEXT STEP When a specimen screens as a strong candidate, the app produces a one page screening summary you can save and take to a laboratory. It records what was checked, what was ruled out, and the reasoning behind the result, so a lab can assess the specimen quickly. Screening is not confirmation. Only a hands-on examination and, where needed, laboratory analysis can identify a meteorite.

Most rock identification apps stop at a name. GemTrail: Rock Identifier turns every stone photo into a specimen-style record with visible evidence, confidence indicators, recheck guidance, and a polished card you can save or share. Take a photo of a rock, mineral, crystal, or gemstone with your camera, or choose an existing image from your photo library. The app analyzes visible characteristics, suggests the closest possible match, and explains why the result may fit—including color, texture, structure, lighting, visible details, similar materials, and recommended next checks. Build a More Organized Collection * Identify rocks, minerals, crystals, and gemstones from photos * Review confidence and photo-quality indicators before relying on a result * Save each specimen with its image, suggested match, source, date, notes, and status * Mark favorites and quickly find samples that need further review * Retake photos when lighting, focus, or visible details are insufficient * Browse a built-in reference library featuring 140 common rocks, minerals, crystals, and gems * Compare similar materials using practical clues such as luster, hardness, streak, texture, and formation * Create a polished Stone Specimen Card to save or share Designed for Curious Collectors Whether you are a collector, student, hobby geologist, lapidary learner, crystal seller, outdoor explorer, or simply curious about a stone you found, the app provides more than a quick label. Each identification keeps the supporting information attached to the specimen, helping you review uncertain results, explain your findings, and organize your growing collection. User-Controlled Photo Access Camera and photo-library actions are initiated by you. Choose or capture a specimen, review the result, and decide what you want to save or share. Important Identification Notice Photo-based identification provides an educational starting point and should not be treated as a certified geological, gemological, safety, or monetary appraisal. Results may be affected by lighting, image quality, surface condition, camera angle, and similarities between materials. For valuable, rare, hazardous, or safety-sensitive specimens, confirm the result through physical testing or consultation with a qualified professional. Subscription Information Payment will be charged to your Apple Account upon confirmation of purchase. The subscription automatically renews unless canceled at least 24 hours before the end of the current billing period.
