The Nokia Thermo allows you to measure your body temperature or that of a family member with a single movement. Move the thermometer from your forehead to your temple and know if you're having a fever within a few seconds. The green, orange or red color on the display indicate how high your fever is. The body thermometer can be linked to your iOS or Android device. Use the Nokia app to store your data in an easy way. This is useful if the thermometer lights up red and you'd like to be reminded to take another measurement later or if you want to take your information to the doctor.
