### 1/5 — Don’t bother

*2023-09-14, version 1.0.1*

Terrible the actual crystals don’t even come up as an option

### 1/5 — Can’t scan rock

*2023-08-07, version 1.0.1*

Keeps saying it can’t scan the rock. Have tried different ways and different rocks. It doesn’t give any feedback on why it can’t scan..

### 1/5 — This app has too much bugs

*2023-06-09*

So when I scan the crystals like lapiz, rose quarts, Smokey quarts and it says Smokey quarts is JADE? Also it says lapiz is GOLD? Plz fix it

### 2/5 — Not fully

*2023-01-23*

It got some right but some of the easiest ones it got wrong

### 1/5 — Don’t waste your money

*2023-01-09*

This is the worst app. It scans and then comes up with the same three choices for every Crystal I scan

### 1/5 — Terrible App

*2022-09-15*

Why does it keep asking me if what it guesses is correct? If I knew what the stones were I wouldn’t need the app. Useless.

### 1/5 — Not accurate definitely don’t pay

*2022-09-11, version 1.0.1*

It gave me 4 choices for each gem and some wildly out. Eg showing g a black tourmaline for a pale blue gem. It identified 50% of my collection only because I already knew what they were. It didn’t recognise my Jade, garnet, lapis lazuli any clear ones, blue correctly or any brown correctly. If I didn’t know what it was then no hope. The sodalite is white but on the app shows as a blue gem. No option to search for correct one. I did like it saving the photo in a collection but deleted the app as it is sadly useless.

### 1/5 — The worst!

*2022-08-22, version 1.0.1*

Seriously so far off. This has got to be the worst app for trying to identify anything.

### 1/5 — Crystal ID

*2022-07-24, version 1.0.1*

Didn’t identify the crystals correctly . It had lots of adverts

### 3/5 — not great

*2022-06-18, version 1.0.1*

when l get to the premium part I just can’t get into the actual app!! l mean it’s good it was free! so if you get this app don’t get your hopes up.
