Finally you can use your smartphone as a thermometer. No need to rely on apps that only show a rough estimate of temperature in that area.
Thermodo is sensitive, portable, lightweight, durable, and attached to its (included) keyring.
Simply plug Thermodo into your Android or iOS device’s audio jack to immediately record the ambient temperature right on the spot. Read the temperature on the free app.
It also shows if the temperature is and if the temperature is rising or falling.
Thermodo comes in two versions: a basic model in black, red, or silver ($29.99) and a premium version ($44.99) in a brushed aluminum finish with engraved logos.
