VReg Temp app for iPhone and iPad

The app comes loaded with some reasonable default values. Adjust the sliders to set the input voltage, the output voltage, and the expected current draw. If the heat generated exceeds the manufacturers specs, the JUNCTION TEMPERATURE will turn red to let you know. That setting and other are found by pressing the hamburger menu. The slider ranges are configurable for easier tweaking in you desired range. If the slider wont easily stop on your desired setting, you can make fine adjustments with the steppers next to them.
