No cost, works great – View Source Review

Adding “view source” in the share menu makes this thing great. If you aren’t seeing that on yours go to share in safari (or other browser), slide all the way to the last item “More” and find it in the list. You can re-order it as one of the first items from there. A “pretty print” feature would be nice, but even without this is what I was looking for.
