SciCalc82 is a simple scientific calculator designed to evoke the style of the early 1980s. This iPhone app is easy to use and will feel familiar to those of us who grew up during that era.

The calculator adds a touch of realism with its retro look and feel, including the layout, key click sounds, LCD display digits, and response. The functions and operations are just as you remember them, but SciCalc82 also includes a few more features that you may have wished you had back then, making it a modern-day usable device.

For quick help, you can find the green [INV] button in the upper left corner, which serves as the "shift" or "2nd" function button. Additionally, if you press and hold the blue [MODE] (HELP) button, you can access web-based help for further assistance.
