New updates are available for Spoke Tensioner.  I changed from a simple moving average to an exponential moving average.  What this means is that the most recent sample is weighted more heavily than then previous samples. It helps eliminate the "pluck" being registered as the frequency.  Instead the ringing of the spoke is more clear.

Also, I updated for iOS 7 interface.  There was a little bit of moving things around to make them agree with older versions such as iOS 6.  As a result, some of the colors are not ideal, but I hope this is a worthwhile compromise for the improved functionality of the app.

Updated for iOS 7 UI
