ReceptionRating · Positive reviews · Number of ratings

Vitamin D™ · UV Index holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sunlight Tracking by Riseroo has 25 ratings behind it against 1, so its average is the more settled of the two. 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.

UpkeepUpdate frequency

Sunlight Tracking by Riseroo ships an update every 6 days, Vitamin D™ · UV Index every 4 weeks. The most recent releases landed on June 4, 2026 and September 3, 2026 respectively.
