WHY GEOLOGY TOOLKIT?
✨ Customizable: Pin your favorite features to the dashboard for quick access.
✨ Offline Capable: Most databases and tools work without an internet connection (perfect for the field).
✨ Monthly Updates: New content and features added regularly.
Note: This application is intended as a virtual manual and guide for disciplines like Mineralogy, Crystallography, and Petrology. It is a powerful companion but does not replace university classes or dedicated professional books.
What's New

Awesome app! Plenty of material to keep you busy and learn from! The 'handy rock identification' keeps it super simple and perfect for what I would need it for out in the field! In the microscope section, I would like to see cleavages and other features highlighted on the pictures at some point in the future (I suck at microscope work 😆) Keep up the good work!
Speak Truth
I noticed the further you zoom in the data changes significantly. I am also wondering if this was a one time purchase or will I continued to be billed? I can't find any info on that. Thanks, Too many crashes. I un-installed the app and re-installed, works alot better now. I really like this app, very informative. Would be super cool to have a microscope & UV light opinion. Yes, about the zooming in/out. It says something different if you make the square smaller. Thank you for the app!

Great app idea! Needs a lot of work though. The prediction part is 90% of the time. Anything with white on it is a opal. The a pic with the flash and its 1 thing. Take a pic of the same specimin without flash and it's something else. Other parts of the app are cool and educational. However this app is not worth the 10 bucks I paid for it. It really should be free.b

No zoom, no screenshot, no print. Without these features many of these public domain charts and figures are not usable or legible. Why lock up this functionality? You don't own the copyright to any of them. Most are available on Wiki Commons. I don't mind you charging for your labor as an aggregator of content. I think it is very arrogant of you to restrict these useful functions. You defeat the purpose of the app by restricting this functionality.
