I like this app. Useful fast info and I'm looking forward to the addition of more tools! Installed easy with no spying junk. This replaces 4 windows I keep open on my phone for the same info.

UPDATED REVIEW: I misunderstood the UI in my original review. Thanks to the dev for following up and clarifying. The app works great and does what it's supposed to do! ORIGINAL REVIEW: The weights/prices for some of the 90% are way off. It priced silver dimes and quarters both at $48+ each. If I recall it said they each contain 0.7+ oz of silver. I like the app design and ease, but if the math ain't mathing, it's pointless.

I think you're mis-understanding the UI. It's asking for total face value, not total number of coins. So to caluclate a dime you would enter 0.10 and a quarter 0.25, not 1.00. I hope this helps and if so, I'd love an updated review. Thanks so much for trying the app regardless! Edit: I'm updating the tool-tips to be a bit more clear also. :)
