5 Stars - Killer App From Good Guys
"Works like a charm"

Pennyweight simplifies the way you determine the value of gold, silver, platinum, and palladium based on weight, market price, fineness, and buy/sell percentages. Instead of recalling the formula and going through all of the steps and calculations, all you need to do is enter a few simple details into the app to streamline the whole procedure and get your customers processed quickly. Just select the purity, unit of measure (troy ounces, pennyweight, or grams), and enter the weight. Pennyweight will automatically show you the value based on the current market price.

Some of the features of Pennyweight include:
* Quickly calculates values for gold, silver, platinum, and palladium.
* Live market feeds and 24 hour charts from
* Instant access to New York Spot and London Fix market prices.
* Calculate value based on the current market price, yesterday's close, or a custom price.
* Historical charts from in 30 day, 60 day, 6 month, 1 year, 5 year, and 10 year increments.
* Ability to set margin percentages for buying and selling (e.g. buying at 60% and selling at 120% of market price).
* Privacy options include the ability to show or hide market prices on the main screen and set margin percentages on a separate screen so they are not visible to customers.
* Feedback on the transaction and calculated value on a per unit basis (e.g. “Buying at $22.87 per dwt”).
* Separate configuration settings and values for each alloy.
* Cached memory that stores all settings and values between sessions. Safely exit the application to answer a call or use another app and resume where you left off.
* Support for currencies of more than 125 countries.

Pennyweight lets you personalize your results to give you the exact information you want. Just choose margins for buying, selling, or both; or set a different margin percentage for each fineness.

I use to use this app daily. It worked fine until the beginning of August 2016 when the Kitco spot information stopped updating on the app rendering it totally useless. I wrote the developer two times, have not heard any response, and it still is not updating. I deleted the app and reinstalled it to no avail. I now uploaded the free Kitco app which basically does what this app used to do and I am very pleased using their app instead of Pennyweight. UPDATE: finally working again thanks to recent update from the developer that only took a few months to fix. I still like using this app when it works. Thanks.

Used to be 5 Stars...Now 0 Stars...Crashes

This app used to be awesome! In fact, it used to be the best for precious metal dealers. I'm not sure what happened with the last update, but now all it does is crashes when you open it. It's really unfortunate.

Calculations are always off

Seems the spot prices are always off when calculating my holdings. I love the ease of the interface, but it just doesn't work.
