Mineral Database

This is no fault of the app or developers, but some of the reviews made it seem like it might be a fit for identifying minerals while rockhounding, and it is not, so do not lose your $10 like I did! For example, trying to learn about jasper showed me the entry for quartz. Completely understand why, but totally not at all what I needed. My knowledge is pretty basic so maybe more seasoned folks could get more use out of it; the app functions very well as far as I can tell!

Good for looking up minerals easy to use good price nice pictures

This review is specifically to highlight that this app lacks the option to display its contents in both portrait and landscape mode. Developer, please feel free to let me know if/when you upgrade the app accordingly and I will be happy to amend (and flesh out my review). Meanwhile, I feel like I wasted my money — this is an accessibility issue for me and the lack of landscape mode means I will be far less comfortable viewing its contents on my iPad. Thanks in advance if you upgrade the app...

I use this app to look up minerals that I own or want to add to my collection. The search function is easy and the results are very detailed and helpful. Highly recommended!

I love the 3D structure renderings that can rotated. But the interface is modal, so you must back out of a listing just to see the photos! There should be but a single screen for each mineral that I can just scroll. I would also appreciate a wiggle mode for the 3D structures.

Would have given a 5 star rating if it had more pictures!!

Finally! Professional and advanced armatures rejoice - this is the app for which you have waited. Brilliant. A must.

Should have expected this to come from Tasa. Every serious geologist should have a copy, the only thing I would like to add is the capacity to create a custom library. Again - awesome app! Well done guys!

Great app for helping identify minerals. Some of the optical properties are missing and the organization is lacking. For example if you look up chlorite there is no general formula or properties for a crucial mineral. They have end members with some properties. Overall great app, maybe worth 5. Not 10.

This is an easy reference to identify minerals with stunning photographs. Although the photomicrographs are not the best examples for id under the scope. I am a geology undergrad student who used the mineralogy textbook written by the same authors who make this app. If you are familiar with the book you will find this to be similar to the database on the cd, only with a very nice iPad interface. Searches are made easier with results that do not take you away from the search page. I wish there were more photomicrographs for the big ten minerals at least. The only example for albite shows zoning with an arrow but does not make this clear anywhere, there should be a few examples to help with identifying these minerals under the scope. For the rock hound this app is five stars.
