*2026-07-22, version 1.0.26*

Hard to work when I press something it does not work other than taking a picture!

### 1/5 — not worth a try

*2026-06-21, version 1.0.26*

### 1/5 — Junk

*2026-04-09, version 1.0.26*

This app does not work at all, and I mean it just does absolutely nothing

### 1/5 — Doesn’t function

*2026-04-04, version 1.0.26*

You take a photo and nothing happens, none of the menus are able to be pressed. Wish it worked cause it seems like it would be awesome

### 1/5 — Won’t work

*2026-03-21, version 1.0.26*

Tried with 2 different rocks/ crystals and after the photo was taken nothing happened. It went back to the main screen and did nothing.

### 1/5 — Not working

*2026-03-15, version 1.0.26*

app completely non responsive to input

### 1/5 — How does the app work???

*2026-03-08, version 1.0.26*

I swipe, click, refresh but I can’t go to any place but the photo when I took the picture it took me back to my dashboard and it was my first day

### 5/5 — review

*2026-01-23, version 1.0.26*

Great app i think that this is a reliable app it works really well.

### 5/5 — Amateur Miner Pro Reviewer

*2025-07-20, version 1.0.26*

So far, without the ability to confirm the readings and the accuracy of any of these results, the ability for the app to maintain consistent numbers as I go about extracting minerals, and cleaning some things up, it seems to all fall perfectly in line, and once I get some results that can confirm the accuracy of these numbers from this app I will. But until then, this has been so far an awesome app!

### 2/5 — too good to be true.

*2025-07-20, version 1.0.26*

I was so intrigued to get this app with all the great qualities it portrayed. But when I decided to download it, it wasn’t as favorable as I had expected.
It kept giving me like 50+ results for the pictures I took so I had no idea which rock it actually was. So then I started taking pictures of rocks that I had already figured out the name of, and the results were so far off.
All the answers that this app gave me were invalid.

#Incorrectly identified just about all of my rocks.
