Verdict
The clearest difference is update cadence: spf.today at every 5 days against Caffeine App's monthly. spf.today also leads on review sentiment (89% vs 74%). Caffeine App's advantage is ratings volume (340 vs 35) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
