I am trying to track the frame rate when performaing certain actions on my mobile device.

Scenario: I open my game via the device browser and run through specific actions. Preferably would like the frame rate stored somewhere, like a text file. Would settle for visual display if that is not possible.

Since you apparently don't want this for the end user, I'd suggest just running with the performance monitor.

With your device connected try running:

Run -> Run With Performance Tool -> OpenGL ES.

That'll give you Core Animation FPS, but also loads of other stats about your application, which is probably more helpful to you if you're trying to assess performance issues.
