For when I can't go outside walking, or I want to change things up, I got a Wii Fit U with the pedometer. This allows me to get "points" and virtual rewards for working out. While it's kind of silly, these things really do encourage me to keep going.
The Wii Fit U software does graphing and tracking of goals, but I find it's not as detailed or featureful as the Fitbit versions, so I tend not to use it.
