Tricorder - an Android App

In Star Trek, when Spock landed on an unfamiliar planet he pulled out his trusty tricorder to scientifically analyze the world around him.

"Tricorder" is an Android app that, rather amazingly, allows you to do the same thing.

It's a lot of fun to see the data pouring out of the phone's amazing set of sensors (accelerometers, magnetic field, microphone, GPS, network speed, etc.). The GPS view also shows a nifty compass.

Radio stations on my Android phone

I have almost a thousand mp3's on my phone, but sometimes I'm in the mood for something new.

Pandora is not a bad idea.

Another is the I Heart Radio app. You only get the radio stations in their "network", but that's dozens or hundreds of stations. So far it's working well for me (but I do have a WiFi connection here).
