### 5/5 — Please 64Bit

*2017-03-29, version 2.0.2*

10.3 update flags this oh so useful database app as 32bit.  PLEASE UPDATE, please!

### 1/5 — Not good

*2012-12-28, version 1.1*

Not at all happy with this.  Not much information.  Wouldn't be worth the price if it was free!

### 2/5 — Not user friendly

*2012-06-29, version 1.1*

Not easy to use. You have to know the classification of a stone ( what it might be a sub type of) to find it. We tried to use it to identify gemstone/ rocks and it was impossible.

### 3/5 — Good start

*2012-01-27, version 1.1*

First thing I noticed is that it does not have amethyst. Really? Also, picture zoom does not zoom. Image is the same size. Only the rest of the app background whites out. Needs to support pinch gestures to zoom pictures.

### 4/5 — Very Good

*2011-10-25, version 1.1*

I like the information provided. The pictures are good quality.  I'd like to see more pictures of what these rocks and gems look like ' in the wild ', as i am a rock hound and appreciate all the help i can get. Thx!
