## What is Geology Kit?

Point your camera at a rock and Geology Toolkit tells you what it is, how it formed and what it is made of, then draws you a labelled pencil sketch of it. One photo, the full story.

Powered by a frontier class AI model, it identifies rocks, minerals, crystals, gems and pebbles, explains the formation history behind each one and gives you the geological detail to go with it: Mohs hardness, lustre, chemical formula, companion minerals and more.

Whether you're a curious walker who picked up something interesting, a rockhound building a collection, a student preparing for fieldwork or a professional out in the field, Geology Toolkit is a considered field guide in your pocket.

What you can do
• Identify rocks, minerals, crystals, gems and pebbles from a photo
• Read the full formation story: how each specimen formed, over what timescale and in what conditions
• Discover the companion minerals commonly found alongside your finds
• Turn any find into a labelled pencil field sketch in seconds
• Save specimens to your personal field guide with sketches, notes and locations
• Get confidence scores and alternative identifications for tricky specimens
• Meet a new Rock of the Day every morning, with a daily quiz to test what you've learned
• Explore What's Beneath: rock columns for places like the Grand Canyon, layer by layer through deep time

Built for serious curiosity
• Rockhounds and collectors building a field guide of finds
• Geology and earth science students studying mineralogy, petrology and classification
• Field professionals needing quick, reliable identification and reference
• Educators and parents exploring geology with curious learners
• Anyone who's ever picked up a stone and wondered what it was

Why Geology Toolkit
Most rock identifier apps stop at a name. Geology Toolkit goes further, explaining why a rock is what it is, how it formed and what to look for in the field. Every identification adds to your personal field guide, building a reference you'll return to.

Available in English, Spanish, German, French, Portuguese and Japanese.

Try it free for 7 days, then subscribe for unlimited identifications, full formation histories, companion mineral data, sketches and an exportable field record.

From photo to real geological understanding, one specimen at a time.

### 2/5 — Missed opportunity

*2026-01-24*

I downloaded this app hoping that it would offer a more data driven approach to rock identification, instead this just seems like a worse implementation of other AI apps. What I really want is to be able to feed the app information like hardness, SG and acid test results so that the AI can use all of that data along with the image to give me the best possible result. If this was implemented I do believe it could quickly become the best identification app for informed hobbyists.

**Developer response:** Thank you so much for the thoughtful feedback - this is a really valuable suggestion.

You’re absolutely right that incorporating additional field data such as hardness, specific gravity, and acid reaction would allow for a more constraint-driven identification process. Combining those inputs with image analysis would move the app closer to a structured diagnostic workflow rather than relying primarily on visual interpretation.

At the moment, Geology Toolkit is focused on making rock identification and learning accessible for students and enthusiasts using image-based analysis. However, expanding toward more data-informed identification for advanced users is something I’m very interested in exploring as the app evolves.

I appreciate you taking the time to share such detailed input - it helps shape where the app can go next!

### 1/5 — Long loading screen

*2025-12-05*

App takes a long time to analyze rock/ mineral

**Developer response:** Thanks for letting us know, and sorry about the slow analysis. We know waiting can be frustrating. Analysis time can vary based on photo details and connection speed, and we’re continuously optimizing performance. Your feedback helps us improve, and we hope you’ll give the app another try.

### 4/5 — purchase

*2025-10-31*

Good app

**Developer response:** Thanks for your feedback! We’re glad you’re enjoying the app. We’re always working on improvements and hope future updates make your experience even better.

Sketches that keep your photo
If a sketch fails, your photo stays where it is and one tap tries again. Momentary errors now retry on their own.

First time here? You'll now get a hands-on introduction: identify a sample specimen, scroll through the Grand Canyon's rock record layer by layer, and meet today's Rock of the Day before you've even set up an account.

Today's rock, on day one
The welcome tour now shows the actual Rock of the Day, with its daily quiz playable right there. Answer it and your result is already waiting on the Discover tab.

### 2.2.0 — 2026-08-25

NEW: What's Beneath

Ever wondered what exactly is under your feet? Now you can find out. The new "What's beneath" section in Discover shows the rock record for your area – every layer, stacked on a timeline spanning millions (sometimes billions) of years.

• See the surface geology where you're standing, with just your approximate location – or look up any place by name
• Scroll a time-scaled column of the rock layers recorded for your region, from yesterday's sediments down to ancient basement rock
• Spot the gaps – missing chapters of deep time, marked right where the record skips. Some regions are missing hundreds of millions of years
• Just identified a rock? Tap "See the rock record beneath this find" on the result to explore the geology where you found it
• Browse hand-checked famous columns – start with the Grand Canyon – no location needed, works offline
