title: Creating progress circle as WKInterfaceImage in Watch App
body: <p>I am trying to create a progress circle for the Apple Watch version of my app. I know that we aren't able to use UIViews (which would make things so much easier!) so I am looking for alternatives.</p>
  
  <p>Basically, I would like to create one of these prototypes:</p>
  
  <p><img src="https://i.stack.imgur.com/atMsh.png" alt="enter image description here"></p>
  
  <p>The way I was hoping to do things was to add the background layers as a normal WKInterfaceImage and then the progress arrow/line on top as a WKInterfaceImage that rotates around the circle based on the percentage calculated.</p>
  
  <p>I have the percentage calculated so basically, what I am looking for is some help with the math code for rotating the arrow.</p>
  
  <p>Does anyone know if this is possible, and could anyone help me out if so? I'm not trying to update the circle while the app is running; it just needs to update when the Watch App launches to correspond with the iOS version.</p>
  
  <p>Thanks!</p>
