United States & United Kingdom
Built for people who pick up stones — weekend rockhounding in the US, beachcombing and mineral-shop visits in the UK. Same science names. Same three free IDs a day.
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. Lore stays optional.
Built from their 1-star reviews
01
Competitors flip names when you rotate the specimen. RockID asks for two or three angles and ranks lookalikes instead of pretending certainty.
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
No card for the free tier. Paid plans start only when you choose them. Cancel on Account — we show the date, not hide it.
04
Three identifications a day on the house. The core loop stays usable without a subscription.
Method
Step 1
Front face, side angle, and a close texture shot. 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
The RockID app is the same account as the web. Photograph a few angles, read the shortlist, and file the piece in your cabinet — even when you are away from a desk.

Hardness 7. Fluorite is softer — a steel point still scratches it.
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
Yes. Photograph two or three angles of the specimen — a creek rock, garden stone, beach pebble, or shop crystal — and RockID returns a shortlist with confidence. It is a visual first pass, not a lab certificate. Confirm with hardness, streak, or heft when lookalikes remain.
Yes. Rockhounds in the United States and collectors in the United Kingdom use the same app. Creek and stream finds, beach pebbles, garden stones, and crystal-shop pieces are all in scope. Science names stay the same on both sides of the Atlantic.
Yes. Photograph a tumbled stone, point, cluster, or shelf piece the same way you would a field find. We return the geological name. Healing copy stays optional and is never mixed into the ID.
Yes. Download RockID from the App Store or Google Play. Three identifications every day, no card. Sign in with the same account you use on arockid.com. Plans bought in the app go through the App Store or Google Play. Plans bought here go through Stripe.
No. Create an account and use three identifications every day. On Field, Season, or a Trail pack, choose how many IDs you need from the dropdown. Field starts at 40 IDs a month. Season starts at 80. Trail pack starts at 20 extra IDs. Nothing is unlimited.
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. Use the same account in both places. 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 — including lookalikes such as quartz versus calcite.
