Verdict
The clearest difference is price: 1Daylight at Free against UV Index Tracker's $0.99. 1Daylight also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). UV Index Tracker's advantage is ads (none vs shown) and update cadence (every 2 months vs every 6 months). On in-app purchases there is nothing between them.
