Verdict
The clearest difference is price: Json Genie at Free against CodeDiff +'s $3.99. Json Genie also leads on rating (4.6 vs 2.0) and update cadence (every 10 days vs every 7 months). CodeDiff +'s advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
