Build Your Own Photo App to Identify Any Rock or Mineral
You found a strange rock on a hike and want to know what it is. Instead of hunting for the best apps to identify anything using your phone’s camera, you can build your own identifier that works exactly the way you want — in minutes.
Why build your own instead of downloading one
Search “identify anything app by picture” and you’ll get a pile of generic apps stuffed with ads, paywalls, and features you’ll never touch. They’re fine. But none of them are yours. They don’t know that you mostly collect river stones, or that you want plain-language answers instead of a wall of mineralogy jargon.
Auto is a camera-first app: you describe what you want, snap a photo, and Auto builds you a personal mini-app — a “Frame” — around it. So the “identify anything lens camera app” you’ve been searching for is one you can just… make. Tailored to your rocks, your collection, your taste.
Build it in Auto
- Open Auto and describe the app you want in plain words — something like “an app that identifies rocks, gems, and minerals from a photo.”
- Tell it what you care about: geological features, rock type, likely origin, hardness — whatever matters to you.
- Snap or upload a photo of a rock. Auto generates a working Frame you can try right away.
- Not quite right? Keep talking to it. Ask for less text, bigger images, or a “collection” view. Each message reshapes the app.
That’s the whole point: you’re not settling for a one-size-fits-all tool. You’re steering.
How someone built theirs
A real Auto user built a rock identifier this way, and their prompts are a nice map of the process.
They started broad: build a rock and gem identification app, similar to a plant-ID app but focused on geological features and rock type. That first prompt alone produced a working Frame.
Then came the polish. The result had too much text, which caused awkward sideways scrolling, so they asked Auto to cut the text in each box down and hide the overflow. Small, specific, the kind of tweak you’d never get from a downloaded app.
They also hit a few build errors along the way — merge-conflict markers in the generated code. They pasted the errors straight back into Auto and asked it to fix them, a couple of times, until it compiled cleanly. Worth knowing: when something breaks, you don’t debug it yourself. You hand the error message back and keep going.
The finished Frame — “Rock ID” — is one of several photo-identifier Frames people have already built in Auto. Proof that this idea works, not something to install.
FAQ
Do I need to know how to code? No. You describe what you want in everyday language and fix problems by pasting errors back to Auto.
How accurate is photo identification? It gives strong, plain-language guesses based on the image. For high-value gems or safety-critical minerals, confirm with an expert.
Can I build something other than a rock identifier? Yes. The same approach works for plants, coins, mushrooms, bugs — any “identify anything from a photo” app idea you have.
How long does it take? The first working version takes minutes. Refining it to fit exactly what you want takes a little longer, and it’s the fun part.
