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.
★★★★★ drybonez2987 · Jan 13, 2024
L really like it that’s why you got five stars but ldid run in to an issue but can't read all the gemstones in less you pay l though this was a free gem app it said contain Ads it looks like you want money to look at the rest of the gems
★☆☆☆☆ 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.
★☆☆☆☆ Nikita Preece · Aug 12, 2024
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.
