Rated 3 out of 5 by AndroidUser Works with Android
I just want to write a counterpoint to the previous review. This sensor does work with Android, but only with the newer phones. Your phone needs to support Bluetooth 4.0, aka BLE, Bluetooth LE, or Bluetooth Low Energy. Even then your fitness app may not support this sensor so do some research before you buy. Hopefully Polar will release their app for Android at some point.
NOTE: Star rating not based on performance, I just wanted to get the info out there.

Rated 3 out of 5 by Joe Great until you leave it in the summer heat with your wet towel
I don't recommend leaving this in your car with a wet towel in the summer. The device died on me and I had to buy a replacement due to moisture. That and I couldn't pry the device open with a quarter to replace the battery and damaged it.
Other than that it's a great device to link up with your iPhone. It's not available for Android which is sad. You're stuck with using an iPhone on this device.
