Verdict

The call

The clearest difference is price: Code Editor at Free against CodeViewer's $0.29. Code Editor also leads on update cadence (every 5 weeks vs every 8 months) and chart position (#99 vs unranked). CodeViewer's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
