Sunlight Tracking by Riseroo also leads on review sentiment (50% vs 29%) and update cadence (every 6 days vs every 4 weeks). Vitamin D™ · UV Index's advantage is rating (5.0 vs 4.7).

Written reviews complicate that: 50% of Sunlight Tracking by Riseroo's written reviews are positive against 29% of Vitamin D™ · UV Index's, so the app with the better star average is not the one people write more warmly about.
