A couple of other things:
Our app is compatible with all Android 4 devices - this should include most phones and tablets released in 2012 and later. You can find your device's version by going to Settings -> About phone (or tablet.)
Dash for Android is currently available for download in several regions worldwide, including the US and EU, but Dash for iPhone is currently available only in the US.
One last note - the iOS and Android versions work with different hardware, so please have a look at the current hardware recommendations.
