Identify, analyse and understand rocks in seconds.
A powerful companion for geology study, exploration and learning - both in the field and lab.
Identify rocks accurately and understand what they’re made of.
Geology Toolkit helps students and enthusiasts move beyond labels and build real geological understanding.
Take a photo of a hand specimen and get clear, structured insights into rock type and mineral composition.
Designed for geology students and serious enthusiasts, Geology Toolkit combines AI-powered rock identification with clear explanations that support learning, study, and confident identification.
Instead of surface-level facts, the app focuses on why a rock is classified the way it is - helping you understand composition, texture, and formation rather than just memorizing names.
Whether you’re studying geology, preparing for fieldwork, or exploring rocks as a hobby, Geology Toolkit is built to support learning over time.
Key Features

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!

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.
Preview before you identify
See your photo before sending it for analysis. Take your time, retake if needed, and tap Identify when you're ready.
Add what you already know
Entering a rock's hardness, luster, colour, or crystal system before identifying helps the AI give you a more accurate result.
Not the right rock? Try again
If the identification doesn't look right, tap "Not this rock?" to get a fresh result - no need to start over.
Labels on sketches
Toggle "Add labels" before generating a sketch to get geologically accurate annotations pointing to key features.
More free uses
Free users now get 5 identifications per week to get the most out of using the app.
