I am about to launch an Android app called Korea Metal Price.
This app displays the Korean selling prices of major raw materials such as aluminum, tin, copper, nickel, zinc, and lead, as well as their prices in USD when converted from the Korean selling prices.
To launch this app, I need more than 20 testers. I kindly request your participation in testing. Please send your email address to hos050@gmail.com to be registered as a tester.
The app can be accessed at the following link:
