Been using Rock Identifier: Stone ID for a couple months now. It’s basically an app that lets you take a photo of a rock and it’ll tell you what kind it is. Pretty solid if you’re into geology and that kind of thing.
Here’s what you do – you just snap a pic of the rock and the app analyzes it. There’s also a database with info on different rocks, which is pretty cool. And you can save your rock photos and collection in the app, which is a nice feature.
Look, if you’re into learning about rocks and minerals, you’ll probably like this app. It’s not perfect – the ID accuracy can be hit or miss sometimes – but overall it does a good job. Worth checking out if you’re curious about the rocks around you.
