Whether you’re a student studying geology or you’re simply just a passionate rockhound like me, being able to quickly and accurately identify rocks and minerals is very important. It can mean the difference between keeping a sought after specimen or throwing it back into the trailings pile.
We live in amazing times. We have the ability to quickly and easily access information that can help us identify rocks and minerals quite accurately. And all of this information is sitting at the tips of our fingers, just waiting for us to access it.
In this article, I’m going to share with you what I’ve found to be the best rock and mineral app. I’m always downloading different geology related apps onto my phone and testing them out. So I felt it was time to share with you what I’ve found after playing around with these apps.
This list of the best rock and mineral identification apps includes apps, which at the time of this writing, are free. So that gives you the option to download them at no cost to test them out for yourself.

1. Smart Geology- Mineral Guide
The Smart Geology- Mineral Guide is going to be your best option when it comes to looking for high quality, free rockhounding apps. It’s incredibly easy to use and has an excellent user interface. As far as free apps goes, this is definitely one of the best for helping you identify minerals you have in your collection.
The “Detect Hand Specimen” feature is probably my favorite part of this app. With it, you are asked a series of questions regarding your unknown specimen, including color, form habit, hardness, basic streak, set of cleavage, type of fracture, luster and specific gravity. After you provide the app with as many answers as possible, it gives you a list of the top 5 minerals it believes you have with an estimated matching percentage of accuracy.
- Features a “Detect Hand-Specimen” option
- A wealth if accurate and in depth information for many different minerals
- Loaded with high quality images and descriptions.
- In-app purchases are inexpensive (but not necessary)
- In the version I tested, when you used the back button it would start you back at the beginning. This was frustrating especially when I only wanted to go back one screen. This is an easy fix and may already have been fixed by the time you read this.
2. Minerals guide: Rocks, Crystals & Gemstones
According to the official app description:
“Minerals guide: Rocks, Crystals & Gemstone is a comprehensive application that allows geologists and hobbyists to examine and explore minerals, rocks, gemstones and crystals features. Geology Toolkit helps you to identify many types of fossils that you will find.

3. Geology Rocks – Handbook of Rocks
This is a good app to use to research your minerals and learn more about them once you already know what they are. So it’s not the best app for identifying rocks and minerals. But, with that said, it’s still worth checking out because the descriptions and information that’s available on the app is worth while.
Features of this app:
- More than 4000 rock types;
- 22 diagrams useful for the identification of Igneous, Sedimentary and Metamorphic rocks;
- Minimalist design;
- Very fast and fully searchable;
- Basic details for each rock type.
4. Geology Toolkit Premium
Ok, I know I said that the geology apps I mention in this article are all free. Well, I thought they would be too. But this list would not be anywhere close to being complete if I didn’t talk about the Premium version of Geology Toolkit.
Even though this app will cost somewhere around $7 to download, it’s worth every penny. This is much more than a rock and mineral identification app. This is a massive resource of information
According to the apps description on Google Play:
“Geology Toolkit is a thoroughly practical, lively and comprehensive application that allows geologists and hobbyists or even kids to examine and explore minerals and rocks features under the petrographic microscope or as hand-specimen.
Whether you are preparing for an essay, studying for an exam or simply want to enrich your hobby or expand your knowledge, Geology Toolkit is your essential guide.
This app is an identification guide to many types of rocks, minerals, and even fossils. Geology Toolkit will guide you on how to recognize some of the rocks and minerals that you will find.”
Stone – Crystal Identification App
Stone is the only app on our list that provide a clean, uncluttered interface. Possibly a little too minimalist: the list of crystals shows beautiful images, but no names; you must examine each gem to learn its identity. It’s a great app to learn or practice crystal identification by picture.
This crystal identification app has a limited database of just 69 crystals. The crystal gallery displays 12 crystals on the screen at once, making it simple to scan through. One disadvantage is that you can’t read the names of crystals until you click on each one. However, you may search for crystals by name or by therapeutic powers, which is pretty handy.
