Verdict

The call

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 (#58 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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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