Call Radiation Indicator

When reception is good the phone reduces power and EMR (Electromagnetic Radiation). If reception is weak, the phone uses maximum power and emits maximum EMR. This app shows when it may be unsafe to put the phone to the ear. It helps reduce SAR (Specific Absorption Rate) - the rate at which radiation is absorbed by the human body.


Danger Radiation Level (Red Skull Icon):
This is when the phone may operate at maximum radiation in order to compensate for the weak cell tower signal. Advisable to avoid putting phone on ear. Use the phone's speaker instead.

Medium Radiation Level (Yellow Caution Icon):
Try to avoid long use when placed on ear (preferably less than 6 mins) to minimize SAR.

Normal Radiation Level (Green Apple Icon):
Phone operates at lower power.

Purple graph is approximation of phone radiation. Higher means max radiation. Lower graph means low radiation.
