Third party software to combine fitness tracking data

Does anyone have any recommendations for third party software where I could combine data from things like Garmin Connect and MyFitnessPal? I'm looking for something that will give me better/more configurable ways to view data and maybe even something that offers some data analysis.

An example that isn't quite what I'm looking for is Runalyze. Runalyze lets you import Garmin or Polar (etc) data and offers a lot of extra analysis, e.g. TRIMP and fatigue. The problem is, as the name suggests, it is heavily focused on running and doesn't support other activities as well. It also doesn't have anything for calorie tracking.
