Quick Calc

This app gives you only a black screen. It is useless for normal android devices.It works as a burn-in protector for plasma and Amoled Screens.On some TV Sticks (mk808) you cannot dim the TV screen and the screen time out is also not working.And if you only want to play only music (Spotify) then it could be possible that the screen will burn-in. Long tap anywhere on the screen to exit the app.

Coupler Directivity Calculator is used to calculate the minimum and maximum values of Reflection Coefficient, VSWR, Return Loss and Mismatch Loss.The Directivity Error Calculator shows the accuracy of a reflection measurement of unknown impedance. It bases its readings on the directivity of the coupler used for the measurement. It is also a convenient way to convert a reflection coefficient to an equivalent standing wave ratio (SWR), return loss, or mismatch loss.LIKE and Share us: Google+: http://gplus.to/androiddesignnl
