If you are an expert in the field and have a colleague nearby to check the stones, it is a perfect app, I prefer the option of Arabic Syrian language.

2 ads within 5 minutes and then with my second click I was told to buy premium. Not enough time to explore the app to even decide if I would buy.

★☆☆☆☆ Joseph Sokolik · May 22, 2023

App used as advertising pro-app. Has pictures and names of rocks. Push the arrow or any place on the app and takes you to an add telling you hou much better the pro app is!! Don't waste your time.

★★☆☆☆ Sandra L. Webster · Dec 10, 2023

Deceiving promo I thought I finally found an app to turn to when I return from a day hicking and collecting a few rocks. Ha! Not so. If you want to look up and research anything, go get yourself a good set of encyclopedias my friends. You will not get anything from here.
