This is the worst app I've ever tried to use. I paid for a premium membership but the app states I don't have premium access and should pay the subscription fee again (I paid for a full year last week). When I try to contact the company through the app's "contact us" form, the message won't send. When I get the "free" info on a rock, half the screen is covered by a white box. So yeah, utterly useless.

We're sorry for the difficulties you've experienced, Heather. Try logging into the same Google Play Store account on your device, then download the app and tap the Restore button in the upper left corner of the subscription page. This should activate your paid features. If you're still having trouble, contact us at support@rockidentifier.com.

This is definitely one of the better rock/crystal identification apps. Other ones I've used don't even come close. I have a few crystals that I'd been having a difficult time identifying and thanks to this app I finally know exactly what I have. It's not perfect, though, it won't accurately identify my multi-stone bracelets. I already know what they are but I wanted to find out if it could get it right, it didn't. If you added that feature, that would be amazing and extremely helpful!

super annoying! when you launch the app it plays music and forces you to watch a very long ad about a free trial for the app. Then it displays a flash page wanting you to accept the free trial, the x to get out of the page has a clickable surface of one pixel, followed by a "are you sure" page with another x with a clickable x of one pixel. The pushiest most annoying one I have ever seen. Might have gotten the app... no way in hell will I give you money now! and you deserve negative stars!
