Very Useful for Gold Buyers

5 Stars easily if it wasnt for a mediocre user interface and spelling errors. This is after all a calculator so the interface needs user input to calculate the type of precious metal (Spot price is calculated instantly and is updated when you start the app and again anytime you push the price button again), also, the user must choose the weight type (Troy Ounce, Gram, Grains (spelled wrong in app "Grian", very annoying), etc.), then the purity in the metal, then percentage of spot (Percent is also spelled wrong in the app).

When clicking through these options, there is no [Done] button to return back to interface, for example, when you spin the purity wheel in Gold from 10K to 18K, you are stuck at the wheel, I could only figure out to click outside the wheel on the GUI to get back to it.

Aside from all of the other great ideas in previous reviews I still say it is a very useful app and I use a metal detector so I find gold jewelry all the time, this gives me a quick value right in the field. Because this is how "I" use it, I really liked the idea of having the future ability to save a calculation and to be able to take a picture along with that entry, and when its in the saved folder and named, all calculations are updated immediately to spot when you view the folder containing your saves. Also in gold . . . The ability to enter a numerical amount besides the preset standards on the wheel (10k, 14k, 18k, 22k, 24k, etc.). I want to have the ability to enter .825, etc. Maybe even have a button that launches a quick popup window with a conversion chart (.750 = 18k, etc.).
