Good overall
This is a good app. I tested it on 3 2023 Canadian coins and it got 2 right. The issues I see is that the camera uses a fixed focus so you have to move your phone backwards and forward until the focus is right, and then after that resize the image you took. It’ll be much simpler if the camera handles the focus and the app has a predefined circle where the coin must fit. It’s hard to take a picture. The other issue is pricing, this is in no way a free app. You have to pay even for the first picture. Or activate a free trial.
