Comments on RocKnow: Rock ID & Collection for Android

★★★★★ Michael Jahr · Jun 17, 2026

Amazing. A must for rock and gem enthusiasts. Accurate and extremely informative 10 stars.

★★★★☆ Gary Bate · Aug 20, 2026

Hmmm well uses AI for identification. So you will likely get same results using AI to search on Google. It's free to do that BTW. There is a pay wall here, but you can use the app for free if you just ignore that screen. However, if you're a newbie to rock hounding or even rock and mineral collecting it might be worth $39.99 a year for full access to the app. I literally just downloaded it, and it has correctly ID the rocks (2) from my collection...... we'll see?

★★★★★ Melissa Jones · Jul 28, 2026

So far seems great with identifying bought stones....ready to go look for rocks

★★★★★ Alicia Hilton · Jun 12, 2026

So far I find this app very interesting and contains loads of information about any rock/Jem you can thank of. I haven't even paid for the premium yet, differently worth your time to check the app out

★★★★★ Jillian Collins · Jul 8, 2026

This app is a game-changer for rock hounding! It’s incredibly easy to use out in the field—I just snap a quick photo, and it instantly gives me all the details I need. The estimated stone value feature is the ultimate bonus. Highly recommend!

★★☆☆☆ Jeannie Seibert · Feb 9, 2026

I got a bunch of rocks, and I wanted to identify them, so I subscribed to the app for the year thinking I can use this to identify all the rocks that my kids and I get. But after about 10 rocks I get this message,"sending requests to quickly" if I'm going to pay for the app I want to be able to identify all the rocks that I have.

★☆☆☆☆ Jessica Nanik · Jul 3, 2026

Incorrect Identification. Misidentified three crystals. Larvakite it identified as elaborate, nuummite was identified as onyx and my elaborate was identified as fake.

★☆☆☆☆ ben wollschlager · Mar 18, 2026

Couldn't get it to identify a single rock of any type. Kept saying insufficient data. Try again. ZERO Stars

★☆☆☆☆ El Captain Hefe · Mar 3, 2026

After downloading the app I decided to test it I started easy with some petrified wood I have it said it was Jasper then I tried banded agate it again said Jasper, so I tried Jasper, and it said Quartz everything I tried was either Jasper or quartz it hasn't correctly identified a single rock so this app is utterly useless if I could give it a negative rating I would
