Needs more minerals! This is a fantastic app. I downloaded it as a mineral guide for a geology midterm and it's a great reference for mineral ID/characteristics. One thing that I would like to see is a large expansion on supported mineral types because the current 50 are a bit lacking.
Great app, Developer responds to complaints I emailed the developer about the inability to move the app to the SD card. The next day an update was up that gave the ability to go between SD and phone, freeing up the tiny space I still have left on my phone. Fantastic work.
Perfect for caving I frequent the caves in my area as a hobby and was surpised to see how well this app works. The perfect companion!
Can't read The first two questions I am unable to read the options. Will re rate if problem is fixed
So many minerals left out Disappointed how many basic minerals are not included in this app. Also the testing thing is a joke.
50 minerals Thought the developers would have updated the database since 2013. Didn't mind paying a buck but kind of expected more from a non free app.
The app can be moved to the SD card!
The app requires less memory!
Improved app icon and high resolution icon
Ability to turn off background images through options page
