I’d definitely recommend for rock enthusiasts

I have been rockhounding and collecting rocks lately, then I just discovered Gemius. It is really good for identifying rocks and getting more insights about them. Sometimes the results are not %100 accurate if the photo is not taken properly; however, shooting from different angles work well! I recommend it for anyone who is interested in rocks and crystals!!

I got this app to test it on my crystals to see if it even worked. And it shocked me!! I didn't think it’d work at all. I love this app sm it has helped me collect crystals!! definitely recommend it to anyone who loves to research about crystals or rocks in general.<3

Good Developers

I wanted to give this app a try regardless the negative reviews. Tho the results are not %100, I am satisfied enough with the performance. You gotta take the photos with good lighting and from a closer perspective 👍🏼
