# SunkissTimer vs SPF

The clearest difference is ads: SPF at none against SunkissTimer's shown. SPF also leads on ratings volume (5K vs 75) and rating (4.6 vs 4.3). SunkissTimer's advantage is review sentiment (52% vs 32%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. SunkissTimer sells 3 in-app purchases, starting at $5.99 per 7 days and SPF sells 7 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SPF holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: SPF has 5K ratings behind it against 75, so its average is the more settled of the two. Written reviews complicate that: 52% of SunkissTimer's written reviews are positive against 32% of SPF's, so the app with the better star average is not the one people write more warmly about.

SunkissTimer ships an update every 10 days, SPF weekly. Both last shipped on September 26, 2026.
