Verdict
The clearest difference is price: Thermometer at Free against Water Temperature's $2.99. Thermometer also leads on rating (4.4 vs 3.5) and update cadence (every 2 months vs every 16 months). Water Temperature's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
