Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. UV Index sells 10 in-app purchases, starting at $1.99 per 7 days and SunkissTimer sells 3 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
