Verdict
The clearest difference is update cadence: Cup Buddy at every 4 days against Caffeine App's monthly. Cup Buddy also leads on review sentiment (100% vs 74%) and iOS requirement (16.0 vs 18.0). Caffeine App's advantage is device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
