# SPF vs Sunglow

The clearest difference is review sentiment: Sunglow at 100% against SPF's 32%. Sunglow also leads on rating (4.9 vs 4.6) and update cadence (every 2 days vs weekly). SPF's advantage is ratings volume (5K vs 27) and chart position (#57 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SPF sells 7 in-app purchases, starting at $0.99 per 7 days and Sunglow sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sunglow holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: SPF has 5K ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 32% of SPF's written reviews are positive against 100% of Sunglow's.

SPF ships an update weekly, Sunglow every 2 days. Both last shipped on September 23, 2026.
