The app developers at Robocat created a tiny phone temperature sensor called the Thermodo that fits right into the phone jack, giving exact measurements of the temperature in the room.
Previously, Robocat created a temperature-telling app called Thermo, which allowed smartphone users to tell the temperature outside to the exact degree, but not the temperature within their immediate surroundings. Thermodo is an actual thermometer that links to this app so users can determine the exact temperature within each room. It comes fitted with a key ring that can be hooked onto a key chain, keeping the device ready for action.
The Thermodo phone temperature sensor comes in white and black so that users can match it to the color of their iPhone.
