I have published this app here http://www.mypebblefaces.com/apps/22001/10354/ due to some issues with the pebble app store. Here a description:
Automated Repetition counter for weight lifting. The app allows the user to automatically track weight training activities without the need to enter data into the phone. It also displays heartrate and exercise duration. The app allows the user to control an iPhone app to start/stop activities. This app needs the PowerIT iPhone App and Pebble app to work. In order to display heartrate user needs to connect a bluetooth smart enables heartrate monitor such as the Polar H7 to the iPhone PowerIT app.
