Hello, the correct coin needs to be selected before performing the test in order to have a meaningful result. (Otherwise, you can use a musical instrument to get any result you want :D) You can find some best practices here: https://preciouscointester.com/en/best_practices.html
Disappointed
After paying $30 for the device, I expected more options.

Hello, we don't sell any device in our company. Maybe you mean the "pocket pinger". It belongs to a different company. The subscription fee helps us to maintain the app and improve it continuously. We are very sorry for your misunderstanding. If you could point out which pieces of information have misled you, it will be very helpful for us, and will the make it clearer.
Subscription plan likely limiting sales revenue
Subscriptions are generally reviled, so, perhaps you could increase your revenue by figuring a way to segment your prospective customer base.
Maybe a one-time fee for just the *custom* tester (i.e., no access to the coin library).
Or maybe:
One-time fee—say, $9.99—for access to the current database but some additional fee for the annual update (heck, and even a $1.99 annual “maintenance fee” for a “Basic” plan).
For example, I don’t buy rounds; I buy old silver. I’d pay 10 bucks for the current library, but I have no need for annual updates. Let those who need them have the option to buy them.
More money is made via a “Volume, volume, volume!” strategy than by exclusionary pricing. How many new “casual users” could you entice with a lower-priced “Basic” plan?

Hello, Thanks for your suggestions! Our updates are not limited to adding new coins, it also improves precision of existing ones, and fix false positive or false negative results if we found any. These updates help to better protect our users against fake coins. We also need to keep comply with the latest requirements from AppStore, which ensure the sustainability of the service. The subscription model fits the type of our expense for the moment. We will think about your suggestions and it may be more suitable later in the future. Thanks again for your suggestion and understanding!
