Yes. High price for this app, I went through my semi large collection of rocks and jewelry pieces. There are wrong identifications, but you quickly see what throws off the accuracy. I was amused and chagrined to learn my specimens of asteroid were not. It was correct in my nice specimen of moldavite, while also identifying a little ring i had thought was moldavite as a more common specimen. Let me know my fun but inexpensive amber was plastic. Nice to re-identify specimens. Worth it!

Like one of the other reviewers I was really excited for the app and think the concept is perfect. I started the free trial, I experimented on a few crystals that I knew and unfortunately the app got the majority of them wrong. This included crystals such as garnet, purple adventurine, aqua aura quartz, emerald, however it did pick up on citrine, malachite and amazonite. Until the app is more accurate I would not recommend it for now.

This is EXTORTIONATELY priced! Once you download the app for free, you are led to a free trial screen which offers 7 days free trial and then £5 a month subscription cost. Its a rock identifier....plenty of free ones out there for trees, rocks, birds, plants etc. Dont pay for this! EDIT.Yes. I know many apps are free and many are paid for. Yes. I understand the concept of a free app where you pay extra for the full app. This is extortionate and the free app is worthless.
