Verdict
The clearest difference is rating: UV Index at 4.6 against Know Snow's 2.5. UV Index also leads on review sentiment (76% vs 36%) and update cadence (every 5 days vs every 4 weeks). Know Snow's advantage is in-app purchases (none vs 24) and ads (none vs shown). On price and device support there is nothing between them.
