User reviews

Missed opportunity

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.

Response from developer

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!

Long loading screen

App takes a long time to analyze rock/ mineral

Response from developer

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.
