United States & United Kingdom
Built for people who pick up stones — weekend rockhounding in the US, beachcombing and mineral-shop visits in the UK. Science names stay the same on both sides of the Atlantic.
Identify a rock from a photo after a walk along a US creek or a UK stream. Quartz, basalt, sandstone, and jasper show up more often than rare gems.
What stone is this on the shingle, or in a landscaping pile? Photograph a beach pebble or garden stone and get a shortlist instead of a guess.
Identify crystals from a picture — points, clusters, and tumbled stones on a shelf. Geological names first.
Built from their 1-star reviews
01
Competitors flip names when you rotate the specimen. RockID snaps to a closed collector catalog, ranks lookalikes, and hydrates the same facts every time.
02
Phone photos cannot prove a rare gem. Our AI is trained for rocks, stones, and shop crystals, prefers common finds, and almost never returns diamond from a casual snap.
03
The free tier needs no card. Paid plans start only when you choose them. Cancel on Account — we show the date, not hide it.
Method
Step 1
A clear front face is enough. Extra side or texture shots are optional evidence. Works on field rocks and shop crystals. Bad photos get honest low confidence — not a lucky name.
Step 2
Top three candidates, confidence, lookalikes, and why. If the model is unsure, we say so and ask for a hardness or streak test.
Step 3
Save the specimen, add notes, and keep it private. If you want to be found, list it on the Field board with your contact — and take it down anytime.

In the app



Honest limits
Hardness, streak, acid, and heft still matter. RockID writes those next steps on every result so beginners learn the method, not just a name.
iOS & Android
On the App Store the listing is RockSnap. Same RockID account as this site — cabinet and Field board stay in sync when you are away from a desk.

Field board
A specimen stays private until the owner lists it from the app — with a name and a way to reach them. They can mark Smart sell if they want to sell, and take either flag down anytime.
List a piece from the RockID cabinet. Field board
Smart sell is a flag only. RockID is not a marketplace, does not broker sales, does not take payment for specimens, and does not guarantee a sale, identity, or legitimate value. Buyers and sellers deal with each other.

Questions
Billing, the App Store name, and what a photo ID can and cannot do.
Apple lists the RockID iOS app as RockSnap. Search that name in the App Store. Android is RockID on Google Play. Sign in with the same account you use on arockid.com.
On arockid.com you pay with Stripe (card, Apple Pay, or Google Pay). In the iOS or Android app you pay through the App Store or Google Play. An active store plan cannot be changed on the website, and an active website plan cannot be replaced in the store until you cancel it.
Good enough to shortlist common rocks, stones, and shop crystals. Not a lab certificate or jewelry appraisal. When confidence is low we say so and list hardness, streak, acid, and heft tests.
No. Place names on a find are optional and typed by you. We do not request device location.
Website plans: open Account and tap Cancel plan. App plans: manage or cancel in App Store or Google Play subscription settings. Field and Season do not renew if you cancel before the period ends. Trail pack is one-time.
No. Smart sell is a flag the owner can turn on or off. We do not take payment for specimens, broker the deal, or guarantee a sale, identity, or value. You contact the collector directly.
