# UV Index vs Sunwise

The clearest difference is in-app purchases: Sunwise at none against UV Index's 24. Sunwise also leads on ads (none vs shown) and rating (5.0 vs 4.6). UV Index's advantage is update cadence (every 5 days vs every 2 months) and ratings volume (1.1K vs 1). On price, device support and iOS requirement there is nothing between them.

Both are free to download. UV Index sells 24 in-app purchases, starting at $0.99 per 7 days. Sunwise asks for nothing beyond the download.

Sunwise holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: UV Index has 1.1K ratings behind it against 1, so its average is the more settled of the two.

UV Index ships an update every 5 days, Sunwise every 2 months. The most recent releases landed on September 22, 2026 and July 26, 2026 respectively.
