Comments on Rock Identifier - Rockium for Android

★★★★★ MK Ultra · Dec 18, 2025
I like rocks so much that I've been known to smoke em.
★★★★★ Ileen McDowell · Jun 9, 2026
It has identified all of my rocks and gems correctly. Had alot of information about them, and I like that it keeps my collection in the way I want.
★★☆☆☆ Josiah Perisho · Nov 8, 2025
Trapware. You HAVE to sign up to use it, and you HAVE to cancel it to not pay the annual fees.
★☆☆☆☆ curt ehlers · Dec 12, 2025
Horrible. Used 1 time, it provided a basic identification then removed the app. The charges kept coming - weekly! Not worth the charge - look elsewhere for a better app. This is NOT the one.
