I forgot to update my card info on my Apple Pay so I had to enter in my security code and expiration for my card. So I did and then it brought me back to the app. Was about to hit continue to sign up for the free trial when I noticed the total per week had now changed to $12.99 per week instead of the $9.99 like it was literally 2 minutes earlier. I can’t stand that last min sleight of hand trying to pull a fast one on you. I wouldn’t trust this app if I were you. ### 1/5 — Doesn’t work *2025-05-09* Tested with some stones I know are real and it said they weren’t so waste of time **Developer response:** Hello! Sorry to hear about your experience! We understand the importance of accuracy and are already planning updates to enhance the recognition quality. ### 1/5 — Joke *2025-04-07* Try to cancel this app…it’s impossible… ### 1/5 — Worst App Ever *2025-04-05* Posted a crystal clear picture of a confirmed real diamond and it said it was sodalite. Tried again with a confirmed blue topaz and it said it was agate. This thing is awful and not worth the money or time. **Developer response:** Hello! Thank you for your input! We are constantly expanding our stone database and refining the AI models. Your feedback motivates us! ### 1/5 — Paid and immediately regretted *2025-03-31* Didn’t even work I used multiple different items and it didn’t read not 1 correct! **Developer response:** Hi there! Thank you for sharing your thoughts! We are continuously improving our stone database and recognition algorithms to meet users’ needs. ### 1/5 — Hasn’t gotten a single stone matched correct *2025-03-30* Want my refund of 13$ back **Developer response:** Hello!
