Over the past week I've had the opportunity to play with some fun little devices that let you quantify your surroundings. First, there was the Blue Maestro Tempo, a Bluetooth-enabled temperature-sensing device provides your favorite iOS device with temperature info. As I note in my review, it's accurate, but not exactly portable. Next was the WeatherFlow Wind Meter, a smartly-designed app-enabled anemometer that gives you an idea of how fast the wind is blowing. Now I'm looking at Thermodo, a really small app-enabled thermometer that plugs into the headphone port of your iDevice and communicates with an iOS app to give you an idea of the temperature near your iPhone or iPad.
The basic black Thermodo is quite affordable for anyone who loves the outdoors, with a price tag of just US$29.99. An "anodized aluminium" version is available for $44.99, and is something that Jony Ive would probably be proud of.
Thermodo is tiny -- just 0.4 inches in diameter and 1.4 inches long, weighing 0.2 ounces. That's with the keychain attachment; the actual device only projects out of your headphone port by about .4 inches. If you read my review of Tempo, you probably remember me talking about Ron, a friend who wants a small thermometer that works with his iPhone. Thermodo is exactly the device he was dreaming of, something he can clip onto a keychain and use when he wants a fairly accurate reading of temperature -- anywhere.
To get the device working you just download the company's free accompanying universal iOS app and launch it. Your first indication that this might be a somewhat temperamental device comes with the series of startup screens that warn you that heat from your hand or iOS device may throw your temperature reading out of whack:
