1. I want to take advantage of all the great features!I am actually pretty suprised at how much the free version is! I am excited now and looking at all the photos and comparing them to my specimens.
2. If the free version proved to be better, I will most likely get the pay for the version you can pay for! It's pretty great to me!Looks awesome but it crashes every time I try to open it.
3. It just needs a rock detector based on a picture you take for beginners like me.Really good for helping to identify minerals under transmitted light microscopy.
4. Labeling it as an "identification guide" or a guide to help you recognize rocks and minerals you find is very ambitious.
5. I would pay for pro version if i could change storage! PS: Is this app also available on my iPhone? What is it called? I had it on my 10" Android tablet, but will have iPhone7 in field, hence that is where it would be most useful.
6. I took one star off because there is no "favorite" list that would allow me to look at my favourite rocks.Too many 'features' are premium.
7. This app sounded great, it might help me, but it just gives you an idea of what could be found in earth's layers...no help to me at all.
8. Am I sitting on a 2500 gem or a precious metal? Still have no idea.Great work! You can tell Dr.
9. His passion for teaching is palpable with such a free (even non expensive premium version) app.
10. I grew up on a property in northern ca foothills and have always loved picking up different shaped and colored rocks.
11. Ads don't always close when you hit skip.Change coding to allow program to install in SD external storage.
