# UV Index vs Sky and Sol UV Tracker

The clearest difference is review sentiment: UV Index at 75% against Sky and Sol UV Tracker's 11%. UV Index also leads on rating (4.6 vs 2.6) and update cadence (every 5 days vs every 2 months). Sky and Sol UV Tracker's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. UV Index sells 24 in-app purchases, starting at $0.99 per 7 days and Sky and Sol UV Tracker sells 2 in-app purchases, starting at $49.99 per year. Whichever you choose, the download price is not the number that matters.

UV Index holds the better App Store score, 4.6 against 2.6. That said, the two scores are not equally well evidenced: UV Index has 1.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 75% of UV Index's written reviews are positive against 11% of Sky and Sol UV Tracker's.

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