You were probably using a difficult-to-operate function calculator. Your friend was probably using the seemingly-convenient "Calculator Hide App" and "Calculator Vault." But, wait a minute. This Pure Gold Calculator definitely doesn't seem to be compatible with those. However, the unique UI and user-friendliness will leave you unable to ignore it. It certainly lacks features like the loan calculator and the car calculator. However, with a little creativity those calculations can be performed as well. Since it has the convenient Calculation History available, getting used to the app's functionality allows you to perform very complicated calculations with ease.
