It is unlikely two different devices will produce the same results. Use the microphone gain slider to increase or decrease sensitivity. Cell phones are not calibrated for accurate dB SPL measurement. Difference phones will produce different values. We normalize the dB SPL levels produced by your cell phone to a range of 0-99 to make it easy to compare results obtained from the same device.
